Sumble
Which team at the account uses the tool, who runs that team, and what it started hiring for last month
Sumble is an account intelligence and hiring signal platform that reads job posts and public people profiles, extracts the technologies, projects, teams, and reporting lines inside each company, and turns changes in them, such as a first mention of a technology, a migration project, a hiring surge, or a new leader, into signals delivered in the web app, Slack, email, an API, or an MCP server; it has a free plan with 500 credits a month and a Pro plan at $99 per user per month.
Overview
Most technographic data answers a company-level question: does this account use Kafka? Sumble tries to answer the team-level one. Its pitch, stated on its own homepage, is the move from "maybe this bank uses Grafana" to "the platform engineering team at this bank uses Grafana, has this many people, is led by this person, and posted a job mentioning it three weeks ago." That is achieved by reading job posts and public professional profiles, extracting entities with custom models, and linking them into a graph of organizations, teams, technologies, projects, and people.
The company was founded in 2022 by Anthony Goldbloom and Ben Hamner, the founders of Kaggle, and is based in San Francisco. It launched its product publicly in April 2024 and came out of stealth in October 2025 with $38.5 million: an $8.5 million seed led by Coatue and a $30 million Series A led by Canaan Partners. At that announcement it told TechCrunch it had 19 enterprise customers, including Snowflake, Figma, Wiz, Vercel, and Elastic, and tens of thousands of users. That is an unusual profile for this category: well funded and enterprise-proven, yet with a genuine free plan and a card-purchasable Pro tier.
For a small team the relevant plans are Free and Pro. Free includes 500 credits a month, technology, job function, and firmographic search filters, a handful of signals a week, and Slack delivery. Pro is $99 per user per month with 9,900 credits, up to 20 signals a day, project filters, people matching and reporting hierarchies, full-text search, outreach drafts built from a company's own job posts, the Ask Sumble agent, and the MCP server. Signing up with a work email grants 30 days of Pro. Browsing is free; credits are spent only when data leaves the platform through exports, API calls, or email reveals.
The constraint is the source. Like TheirStack, Sumble infers technology use from what companies write in job posts, so coverage is deepest for technology companies and companies that hire actively, which its own documentation says plainly. A ten-person services firm that never posts a role is close to invisible. And on the self-serve tiers you do not choose which signals you receive: Free and Pro learn from your browsing and searches, while explicitly configured signals, champion job-change tracking, and CRM and warehouse integrations sit on the sales-led Enterprise plan.
Best for
Small and mid-sized B2B teams selling developer, data, infrastructure, or security products into technical organizations, where knowing which team uses which tool and who leads it is the difference between a relevant email and a generic one, and where one or two people will live in the tool daily.
Not the right fit for
- Anyone selling to companies that rarely post job ads. Local businesses, small services firms, and most very small companies leave little trace in hiring data.
- Teams that want to specify exactly which signals fire, route them to account owners, and sync them to a CRM without a sales conversation. That configuration is Enterprise-only.
- Ecommerce app vendors who need to know what a storefront has installed. Store Leads or BuiltWith read the storefront directly.
- Buyers who need a large contact database for volume outbound. Email reveals cost 10 credits each, so Pro's 9,900 monthly credits cover under a thousand reveals if you spend on nothing else.
- Anyone who needs a certainty that a tool is installed. The source is text in job posts, classified by a model, and should be checked against the linked post before it is quoted to a prospect.
How it works
- 1
Sumble ingests job posts from aggregators and careers pages several times a day and refreshes public professional profiles daily. Custom named entity recognition models pull technologies, teams, projects, and other entities from job descriptions; a second model classifies whether a technology is actually used or only mentioned; entity linking collapses variants such as "k8s" and "Kubernetes" into one record; and posts and organizations are deduplicated across sources before teams, job functions, and parent-subsidiary relationships are assembled into hierarchies.
- 2
You search that graph in the web app by technology, job function, project, industry, location, and size, or in plain English. An organization page shows the account's technology footprint by team, hiring trends over time, team structure, relevant people with their reporting lines, and the underlying job post or profile behind each claim, which appears in a slideover so a rep can check the source.
- 3
Signals are generated daily after each pipeline run: first mentions of a technology by a company or by a specific team, key technology projects such as cloud or data infrastructure migrations, statistically significant accelerations in hiring for a technology or function, new hires with specific skills or in leadership roles, headcount growth, competitor churn, churn of your own product, and keyword tracking. On Free and Pro, Sumble infers which ones you care about from your activity; they arrive in the Signals page, Slack, or email, and you mark them relevant or not to tune future ones.
- 4
Data leaves through CSV exports of up to 10,000 rows, a REST API covering organizations, people, job posts, teams, signals, and AI intelligence briefs, a Slack agent, the Ask Sumble agent in the web app, and an MCP server listed in the Claude and ChatGPT directories. Each extraction draws credits at published rates.
Feature breakdown
24 features in 4 modulesAccount intelligence
What an organization page tells you, and where each fact came from.- Technology footprint by team
- Technologies are mapped to the team that uses them rather than to the company as a whole, with a model distinguishing active use from a passing mention.
- Teams and org structure
- Team trees and job-function hierarchies extracted for covered companies, showing where a function sits and how large it is.
- Reporting lines
- People are linked to managers and direct reports on Pro, which is how you find the budget owner rather than the loudest title.
- Hiring and headcount trends
- Historical trends for technologies, job functions, and headcount, recomputed daily from years of history, so a shift in priorities shows up as a curve rather than a single record.
- Source slideovers
- The job post or profile behind a claim opens alongside it, so a rep can read the actual sentence before using it on a call.
- Intelligence briefs
- AI-written account summaries available in the app, through the API, and through the MCP server, generated from Sumble's structured data.
Signals
The events Sumble watches for, generated daily.- Technology adoption
- Fires on the first mention of a technology by a company, the first mention by a specific team, or any new mention at a tracked organization.
- Key technology projects
- Job posts tied to initiatives such as cloud migration, cloud cost optimization, data infrastructure migration, generative AI projects, microservices migration, and security modernization.
- Hiring acceleration
- Statistically significant rises or falls in hiring for a technology or function over a 12-month window, including declines in a competitor's technology.
- New hires and leaders
- A person with target skills or in a target function starting at a tracked account, with leadership hires distinguished from individual contributors.
- Competitor and own-product churn
- Falling mentions of a competitor's technology combined with migration projects, and the inverse for your own product at existing customers.
- Keyword tracking
- Job posts watched for terms that standard filters miss, such as certifications or stated pain points like technical debt.
- Signal volume by plan
- 7 signals a week on Free and up to 20 a day on Pro, inferred from your activity; configured, unlimited signals and champion job-change alerts are Enterprise features.
Search and prospecting
Finding accounts and people worth contacting.- Organization search
- Filter by technology, job function, industry, location, size, and company tags such as B2B or B2C, venture backed, or recruitment agency, which helps strip agencies out of hiring data.
- Project filters
- On Pro, find companies staffing the specific migrations and initiatives you sell into rather than companies that merely use a technology.
- Natural language and full-text search
- Describe the account you want in plain English, or search the full text of job posts on Pro.
- People matching
- On Pro, tie roles and projects to the right contacts at an account, with email and phone reveals charged in credits.
- Outreach drafts
- Pro generates draft emails built from a company's own job posts, so the hook is something the prospect published rather than a guess.
Agents, API, and delivery
Where the data goes after you find it.- Ask Sumble agent
- A beta agent in the web app on Pro and Enterprise that combines Sumble data with web search, code execution, and file generation to research accounts, rank a book, and draft plays. It charges credits per answer and shows the cost when it finishes.
- Slack agent and alerts
- Pro and Enterprise users can query Sumble from a Slack thread; Free users receive signal alerts in Slack.
- MCP server
- Listed in the Claude and ChatGPT app directories, with custom connections for Cursor, Claude Code, and Gemini CLI. Included on Pro.
- REST API
- Endpoints for organizations, people, job posts, teams, technology and project lookups, signals, intelligence briefs, and saved lists, metered in the same credits as the app.
- CSV exports
- Organization, people, and job exports of up to 10,000 rows, with the credit cost shown before you confirm.
- CRM and warehouse integrations
- Salesforce, HubSpot, Snowflake, Databricks, BigQuery, and cloud storage destinations, listed on the pricing page as Enterprise RevOps and workflow integrations and kept outside the credit system.
Use cases
4 documentedFounder selling an observability tool
The ideal customer runs a particular monitoring stack inside a platform engineering team of a certain size, which no firmographic filter can express.
A Pro search by technology and team size returns the specific teams, their leaders, and the job posts naming the incumbent tool, and the outreach draft opens with a line the prospect's own company published.
Solo account executive with a named book
Sixty accounts, a few hours a week for research, and no way to tell which accounts are moving this month.
Pro's daily signals flag three accounts that started hiring for a migration project, the rep reads the underlying posts in the slideover, and research time goes to the accounts where something changed.
Early-stage RevOps lead sizing a market
Leadership wants a total addressable market count by technology and team, and the available vendor numbers disagree with each other.
Filtered organization exports of a few thousand rows, priced up front in credits, give a checkable list where each company's inclusion traces to a job post.
Technical seller working inside Claude
Account prep happens in an AI assistant, and pasting context in by hand is slow and error-prone.
The Sumble connector from the Claude directory lets the assistant pull a team-level brief and recent signals for an account directly, with credits drawn from the same Pro balance.
Pricing
from $0 (Free, 500 credits a month), then $99 per user per month (Pro)Per-user subscription with a monthly credit allowance. Browsing is free; credits are consumed by exports, API calls, email reveals, and agent answers. Extra credits can be bought and expire after three months.
| Plan | Price | Includes |
|---|---|---|
| Free | $0 per month |
Good for checking whether your market shows up in hiring data at all. The pricing page says 7 signals a week; the documentation says up to 8. |
| Pro | $99 per user, per month |
Buyable by card and aimed at an individual who uses Sumble daily. Credits cannot be shared between users. |
| Enterprise | Custom quoted |
Sales-led, and where most of the team-wide automation lives. |
Billing notes
- Pro is published at $99 per user per month; no annual price or discount is published.
- Credit rates are published: organization exports and API rows cost 5 credits per row per filter term, people records 1 credit, job posts 3 credits, organization enrichment 5 credits per technology found, and email reveals 10 credits per contact.
- Technology categories count every technology in the category as a separate filter term, so a category of three tools costs 15 credits a row.
- Monthly credits do not roll over, purchased credits expire three months after purchase, and credits are non-refundable. Packages above 25,000 credits go through sales.
- Credits belong to each user and cannot be pooled across a team except through an Enterprise company credit pool.
- The API reference prices several endpoints differently from the credits page, per record plus per paid attribute, and lists phone reveals at 80 credits each, so check the endpoint page before budgeting an integration.
Value assessment: For one daily user, Pro at $99 a month buys a level of team and project detail that elsewhere in this category arrives only with an enterprise contract, plus an agent, the MCP server, and roughly 9,900 credits of exports or API calls. The credit maths need attention: an organization export filtered on two technologies costs 10 credits a row, so the monthly allowance is about 990 such rows, and email reveals at 10 credits each disappear quickly. Free is generous enough to confirm your market is visible before paying. The value drops for a team of five who each need Pro seats and still want signals routed and synced to a CRM, because that pushes the purchase into Enterprise pricing that is not published.

Strengths & limitations
Strengths
- Team-level technology mapping with reporting lines is more specific than company-level technographics, and it is what makes an opening line credible.
- Every claim links to the job post or profile it came from, and a relation model tries to separate real use from a passing mention.
- A real free plan and a 30-day Pro trial without a card let a small team test coverage of its market before spending anything.
- Signal types go beyond hiring volume to projects, new leaders, competitor churn, and keyword tracking, generated daily.
- The MCP server is in the Claude and ChatGPT directories and included on Pro, alongside a documented REST API.
- A well-funded company with named enterprise customers, which reduces the vendor risk common among small signal tools.
Limitations
- Coverage follows hiring. The documentation itself says data is deepest for technology companies and active hirers, so slow-hiring and small businesses are thinly covered.
- On Free and Pro you cannot configure which signals fire; they are inferred from your activity. Explicit signal definitions, routing, and champion tracking are Enterprise-only.
- CRM and warehouse integrations are listed as Enterprise features, so self-serve users move data through CSV, the API, or the MCP server.
- Per-user pricing and non-shareable credits make a team of several Pro users expensive relative to credit-pooled rivals such as TheirStack.
- Credit costs multiply with filter terms, which makes broad exports costlier than the headline allowance suggests.
- Public figures disagree on scale: the documentation describes hundreds of thousands of organizations, while TechCrunch reported a knowledge graph covering about 2.6 million companies.
Head-to-head comparisons
4 alternativesSumble vs TheirStack
from Free tier on signup, then $49 per month for 1,500 credits or $109 once for 1,000 creditsBoth read job posts to infer technology. TheirStack sells the broadest raw hiring corpus with unlimited seats, API access in the same credits, and one-time packs from $109, and stops at company-level records. Sumble goes further inside each account, mapping tools to teams, people, and reporting lines and generating project and leadership signals, but prices per user at $99 a month. Choose TheirStack for cheap, wide lists across a team; choose Sumble when a rep needs to know which team and which person before writing.
Full Sumble vs TheirStack comparisonSumble vs BuiltWith
from $0 for individual site lookups, then $295 per month for BasicBuiltWith observes technologies rendered on websites across close to 500 million domains, from $295 a month. Sumble infers internal tools from job posts and attaches them to teams and leaders, from free or $99 a month. Website-visible products such as analytics tags or ecommerce platforms are BuiltWith territory; back-end, data, and infrastructure tools that never appear in public HTML are where Sumble sees what BuiltWith cannot.
Full Sumble vs BuiltWith comparisonSumble vs PredictLeads
from $0 for the first 100 API calls per month, then a $40 monthly minimumPredictLeads sells dated, source-linked records across job openings, technology detections, funding, news, and customer relationships through an API, starting with 100 free calls a month. Sumble is narrower in signal types but far deeper on the organization itself, with teams, people, and a web app a seller can use without code. Developers building their own signal engine lean toward PredictLeads; sellers who want the analysis already done lean toward Sumble.
Full Sumble vs PredictLeads comparisonSumble vs Coresignal
from $49 per month (Mini, 2,500 credits)Coresignal sells raw company, employee, and job posting records by the credit from $49 a month, for teams loading data into their own systems. Sumble does the extraction, linking, and signal generation on similar kinds of public data and presents it as finished account intelligence. Buy Coresignal to build a data product; buy Sumble to prospect with one.
Full Sumble vs Coresignal comparisonPairs well with
7 categoriesSumble is a signals tool, and a team running it still has 7 neighbouring categories to staff. The pick in each is Lusha for B2B data providers, Smartlead for cold email outreach, Zoho CRM for sales CRM, Dripify for LinkedIn outreach, Make for GTM engineering, Leadberry for website visitor identification and Regie.ai for AI SDR agents, each the leading tool in that category on published criteria.
- LushaB2B Data Providers · Best Value
- Because
- Sumble sends buyers elsewhere for a large contact database for volume outbound. Lusha adds useful free tier.
- Benefit
- Lists get built in minutes from filters, rather than bought, scraped, or typed out by hand.
- SmartleadCold Email Outreach · Best Value
- Because
- Sumble lists per-user pricing and non-shareable credits make a team of several Pro among its limits. Smartlead adds aggressive volume pricing at Pro tier and above.
- Benefit
- Outreach goes out on a schedule and replies land in one place instead of a personal inbox.
- Because
- Sumble is built for signals, not CRM. Zoho CRM adds wider Zoho suite.
- Benefit
- Every conversation ends up on a record, so a rep leaving does not take the pipeline with them.
- DripifyLinkedIn Outreach · Best Value
- Because
- Sumble lists credit costs multiply with filter terms among its limits. Dripify adds effective annual pricing undercuts every serious rival.
- Benefit
- A second channel reaches the people who never open email, without a rep doing it by hand.
- MakeGTM Engineering · Best Value
- Because
- Sumble lists public figures disagree on scale among its limits. Make adds best power-per-dollar in mainstream automation.
- Benefit
- The workflow nobody wanted to buy a whole tool for gets built in an afternoon.
- LeadberryWebsite Visitor Identification · Best Value
- Because
- Sumble is built for signals, not visitor ID. Leadberry adds a permanent free plan at 25 leads a month.
- Benefit
- The companies already reading the site become a list, instead of anonymous traffic.
- Regie.aiAI SDR Agents · Best Value
- Because
- Sumble sends buyers elsewhere for a certainty that a tool is installed. Regie.ai adds why-now signal tracking and account ranking.
- Benefit
- Research, writing and sending happen without a headcount, and the meetings still get booked.
Pairings follow the methodology: the leading tool in each complementary category, chosen on published criteria. Placement cannot be purchased.
Full Sumble stackImplementation & onboarding
- Setup time
- Minutes to a first search: sign up with a work email and the 30-day Pro trial starts. Signals take a few days of normal use to calibrate, because Free and Pro infer them from the accounts and technologies you look at.
- Learning curve
- Low for search and account pages. The judgment to learn is reading the source post before trusting a technology or project claim, and modeling credit costs before running a multi-term export.
- Onboarding
- Self-serve on Free and Pro, with detailed documentation and a support route by email and through the API. Customized onboarding is an Enterprise feature.
- Migration notes
- Nothing to import on self-serve plans. Exports and past downloads remain available from the account's export history, so data you have paid for is easy to keep. Signal preferences learned from your activity do not transfer to another vendor.
Platform, API & security
- Platforms
- Web applicationREST APIMCP serverSlack appCSV export
- API
- A REST API with composable endpoints for organizations, people, job posts, and teams, lookups for technologies, projects, and job titles, signals, AI intelligence briefs, and saved lists, authenticated by bearer tokens, metered in credits, and rate limited to 10 requests per second per user. An MCP server is listed in the Claude and ChatGPT directories and supports Cursor, Claude Code, and Gemini CLI through custom connections.

Frequently asked questions
13 questionsWhat is Sumble?
Sumble is an account intelligence platform built from job posts and public professional profiles. It maps which technologies each company uses, which teams use them, who leads those teams, and what projects they are hiring for, then generates signals when those things change and delivers them through the web app, Slack, email, an API, and an MCP server.
How much does Sumble cost?
Free costs nothing and includes 500 credits a month. Pro is $99 per user per month with 9,900 credits, up to 20 signals a day, project filters, people matching, the agent, and the MCP server. Enterprise is quoted. No annual price is published, and extra credits can be bought, expiring three months after purchase.
Is there a free trial?
Yes. Signing up with a work email gives 30 days of Pro, and no credit card is required. After that the account falls back to the free plan unless you upgrade.
Which signals does Sumble own?
Hiring-derived ones: first mentions of a technology by a company or a team, technology projects such as migrations, accelerations or declines in hiring for a skill or function, new hires and new leaders, headcount changes, competitor churn, and keyword mentions in job posts. It does not identify website visitors or monitor social conversations.
How fresh is the data?
The documentation says job posts are ingested several times a day, and profiles, organization data, technologies, teams, trends, and signals are recomputed daily. Old mentions persist in trend history, so filter for recent activity when timing matters.
How do credits work?
Browsing is free. Organization exports and API rows cost 5 credits per row per filter term, people records 1 credit, job posts 3 credits, organization enrichment 5 credits per technology found, and email reveals 10 credits. The agent charges per answer. Monthly credits reset and do not roll over.
Can I choose which signals I get?
Not on Free or Pro. Those plans infer your interests from the organizations you view and the filters you use, and you refine them by marking signals relevant or not. Configuring signal types, technologies, routing, and champion tracking explicitly requires Enterprise.
Does Sumble integrate with my CRM?
Salesforce and HubSpot integrations and warehouse destinations such as Snowflake and Databricks are listed on the pricing page as Enterprise features. On Free and Pro you move data by CSV export, the API, the MCP server, or Slack.
Who is behind Sumble?
Anthony Goldbloom and Ben Hamner, who founded Kaggle, started Sumble in 2022. It is based in San Francisco and announced $38.5 million in funding in October 2025, led by Coatue at seed and Canaan Partners at Series A.
How is Sumble different from TheirStack?
Both infer technology from job posts. TheirStack focuses on a very large posting corpus sold by the credit with unlimited seats and one-time packs. Sumble adds team structure, reporting lines, people, and project signals on top, priced per user. Wide lists favor TheirStack; account-level depth favors Sumble.
What should I pair Sumble with?
Sumble is a signals tool, and a team running it still has 7 neighbouring categories to staff. The pick in each is Lusha for B2B data providers, Smartlead for cold email outreach, Zoho CRM for sales CRM, Dripify for LinkedIn outreach, Make for GTM engineering, Leadberry for website visitor identification and Regie.ai for AI SDR agents, each the leading tool in that category on published criteria.
What do I pair with Sumble for B2B Data Providers?
Lusha. Sumble sends buyers elsewhere for a large contact database for volume outbound. Lusha adds useful free tier.
Is Sumble enough on its own?
For signals, yes. Sumble does not cover cold email outreach, sales CRM and LinkedIn outreach, and its own profile says so; Smartlead, Zoho CRM and Dripify are the tools that fill those gaps.
Editorial verdict
Sumble is the most detailed hiring-signal product a small team can buy with a card. Where other job-post tools tell you a company uses a technology, Sumble tells you which team uses it, who leads that team, and what project it just started staffing, and it links each claim to the post it came from. The free plan and 30-day Pro trial make it cheap to check whether your market is visible in hiring data, which is the question that decides everything, because slow-hiring and small companies barely register. For one daily seller or founder in a technical market, Pro at $99 a month is excellent value. It becomes less of a bargain as the team grows, because seats and credits are per user and the signal configuration, routing, and CRM sync that a team eventually wants sit on an unpublished Enterprise price.
