The short answer
Both sides assessedPredictLeads compared with Sumble
Sumble offers fewer signal types than PredictLeads but much deeper organization detail, with team structures, reporting lines, people, and a web app and agent a seller can use without code, from free or $99 per user per month. Developers assembling their own signal engine should still start with PredictLeads; sellers who want finished account intelligence should look at Sumble.
Sumble compared with PredictLeads
PredictLeads 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.
Choose PredictLeads if
Technical go-to-market teams and developers building their own signal engine, Clay users who want dated source-linked signals inside their tables, and product teams embedding company intelligence into their own application, all of whom want data rather than another dashboard.
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.
Side by side
13 attributes| Attribute | PredictLeads | Sumble |
|---|---|---|
| Category | Signals | Signals |
| Starting price | $0 for the first 100 API calls per month, then a $40 monthly minimum | $0 (Free, 500 credits a month), then $99 per user per month (Pro) |
| Pricing model | Self-serve pay as you go metered by API call, with volume-tiered per-credit rates and a monthly minimum, plus a quoted Enterprise flat-file plan. | 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 plan | Up to 100 free API calls per month, self-serve, with no card required to start building against the API. | 500 credits a month, technology, job function, and firmographic filters, first page of results, 7 signals a week, and Slack delivery. |
| Free trial | A free tier rather than a time-limited trial, available at sign-up | 30 days of Pro when you sign up with a work email, no credit card required |
| Best for | Technical go-to-market teams and developers building their own signal engine, Clay users who want dated source-linked signals inside their tables, and product teams embedding company intelligence into their own application, all of whom want data rather than another dashboard. | 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. |
| Setup time | An hour to a first API response, since the free tier requires no card and the endpoints are conventional REST. Getting to a production motion where signals create tasks is a genuine engineering project of one to three weeks, or an afternoon if you are consuming it inside Clay. | 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 a developer and high for everyone else. The API is straightforward and the documentation covers the datasets clearly, but the hard part is not technical: deciding which combinations of signals actually mean something for your business is judgement work that the product deliberately leaves to you. | 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. |
| Platforms | REST API, Real-time webhooks, Flat files via AWS S3, Google Cloud Storage, and SFTP, MCP endpoint for AI agents | Web application, REST API, MCP server, Slack app, CSV export |

Strengths and limitations
PredictLeads
Strengths
- Every record carries a primary source URL, which is the single most useful quality property in signal data and something most vendors cannot offer.
- Published crawl cadences rather than vague freshness claims: news as often as every eight minutes, job data at least every 36 hours, company sites daily on average.
- Coverage genuinely at scale, including 120 million companies, 270 million historical job records since 2016, and 1.4 billion technology detections.
- Data is crawled first-party rather than licensed from brokers, so errors are fixable at source and the provenance chain is short.
Limitations
- There is no application. No dashboard, no alerts, no inbox, and nothing that tells a salesperson what to do this morning without you building it.
- Company-level only. Nothing about individual people, so champion job changes and person-level intent are outside the product entirely.
- No first-party signals at all: PredictLeads cannot see your website traffic, your product usage, or your email engagement.
- No scoring or prioritisation. Deciding that a funding round plus five engineering hires means an account is in market is logic you write and maintain.
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.
Pricing compared
PredictLeads
Self-serve pay as you go metered by API call, with volume-tiered per-credit rates and a monthly minimum, plus a quoted Enterprise flat-file plan.
- Free$0
- Pay as you go, 101 to 5,000 calls$40 minimum plus $0.04 per credit

- Pay as you go, above 100,000 calls$0.004 falling to $0.002 per credit
- EnterpriseCustom
For a team that can write code or drive a Clay table, PredictLeads is the cheapest credible signal data on the market by a wide margin. A hundred free calls a month to prototype, a $40 floor to go live, and per-call rates that fall to fractions of a cent at scale, against a category where packaged platforms start at thousands of dollars a month for signals they source from providers like this one. The value collapses entirely if you cannot build: there is no interface, no alerting, and no scoring, so a non-technical buyer will spend $40 and get nothing. Judged as a data purchase rather than a software purchase, the coverage numbers, the published crawl cadences, and the source URL on every record make this unusually good value.
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.
Editorial verdict on each
PredictLeads
PredictLeads is what you buy when you have decided to build the signal engine yourself. The coverage is real, the crawl cadences are published rather than implied, and the primary source URL on every record is a quality property almost nobody else in this category offers. Pricing starts free, floors at $40 a month, and falls to fractions of a cent per call, which makes it dramatically cheaper than any packaged platform running on comparable data. The catch is unambiguous and you should not talk yourself past it: there is no dashboard, no alert, and no scoring, so the value only exists if you or your Clay table can turn API responses into something a person acts on. Technical go-to-market teams should treat this as a default component of their stack. Everyone else should buy a tool with an interface and let it worry about where the data came from.
Read the full PredictLeads profileSumble
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.
