The short answer
Both sides assessedSumble compared with TheirStack
Both 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.
TheirStack compared with Sumble
Sumble also infers technology from job posts, but maps it to the team that uses it, the people who lead that team, and project signals such as migrations, with a free plan and Pro at $99 per user per month. TheirStack remains the better buy for wide, cheap company lists shared across a team, with unlimited seats and one-time credit packs; Sumble is the better buy when a rep needs team-level context on a specific account.
Choose Sumble if
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.
Choose TheirStack if
Vendors selling back-office, infrastructure, or developer software whose product never appears on a customer's website, recruiters and staffing firms who need hiring signal at scale, and technical GTM operators who would rather hit an API or an MCP server than click through a dashboard.

| 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. | Twenty minutes to a first list. Sign up, spend free credits on a query against your best-guess ICP, and read the source postings to see whether the extraction is catching what you expected. API integration is another afternoon. |
| 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. | Low for the app, moderate for the judgement. The filters are straightforward; the skill is learning which technology mentions actually indicate ownership rather than aspiration, and building filters that exclude recruitment agency postings. |

Strengths and limitations
Sumble
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.
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.
TheirStack
Strengths
- The job posting source sees software that no website crawler ever will, which makes TheirStack the only practical technographic option for back-office, data, and infrastructure vendors.
- Every extracted signal links back to the source posting, so claims are verifiable rather than a black box, and a rep can quote the actual requirement on a call.
- Ingestion of roughly 300,000 postings a day means the freshness ceiling is about a day, far better than the weekly or opportunistic crawls elsewhere in this category.
- The API is included in the same credit balance as the app rather than priced separately, and MCP servers are available, which is a genuinely developer-friendly posture at this price.
Limitations
- Everything is inference. A technology mentioned in a posting is strong evidence, not proof, and companies routinely list tools they are migrating away from, tools a single team uses, and tools copied from a stale template.
- Companies that do not advertise roles publicly are effectively absent, which skews coverage toward larger and faster-growing organisations and away from small established businesses.
- Recruitment agency postings are a persistent noise source: the hiring company in the record may be the agency rather than the end employer, and filtering that out takes deliberate work.
- No storefront or consumer-web technographics, so ecommerce app vendors get nothing useful here.
Pricing compared
Sumble
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.
- Free$0
- Pro$99
- EnterpriseCustom
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.
TheirStack
Credit-based, sold either as a monthly subscription or as one-time packs with no subscription; unlimited team members and no per-seat charge.
- Free$0
- Monthly API subscription, entry$49
- Monthly API subscription, mid$169
- Monthly API subscription, high volume$400
- One-time credit packs$109
Model it at two volumes. A founder validating a market buys the $109 one-time pack, pulls 1,000 company records with their inferred stacks, and never pays again; at roughly 11 cents a record that is cheap for data nobody else has. A vendor running continuous outbound sits on the $169 monthly plan for 10,000 credits, or around 1.7 cents a credit, and pulls a few thousand qualified companies a month with the API doing the work. At $400 for 50,000 the unit cost falls under a cent. The pricing is the most honest in the category: no seats, no separate API bill, no annual lock-in, and a free tier that actually lets you check whether your buyers appear in job ads before you spend anything.
Editorial verdict on each
Sumble
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.
Read the full Sumble profileTheirStack
TheirStack is the best-priced serious signal tool in this category and the only sensible option if the software you sell lives somewhere a crawler cannot reach. Reading job ads rather than websites is not a clever workaround, it is a structurally better view of a company's internal stack, and 300,000 new postings a day gives it a freshness advantage that weekly-crawl vendors cannot close. Buy the $109 one-time pack first and check whether your buyers actually post job ads, because if they do not, nothing else about the product matters. If they do, the $169 monthly plan with unlimited seats and the API included is a genuinely cheap foundation for an account-selection motion. Just build the verification habit early: this is inference, every record links to the posting it came from, and the teams that read the source before dialling get very different results from the ones that trust the label.
