The short answer
Editorial assessmentTheirStack compared with PredictLeads
PredictLeads covers job openings alongside funding, news, and technographics, with source-linked records and a free tier of 100 API calls a month. TheirStack goes far deeper on the hiring corpus specifically, with 225 million postings and 33,000 technologies extracted from them. Use PredictLeads when you want several signal types in one API contract; use TheirStack when hiring is the signal that matters and you want the deepest version of it.
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 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.
Side by side
13 attributes| Attribute | PredictLeads | TheirStack |
|---|---|---|
| Category | Signals | Signals |
| Starting price | $0 for the first 100 API calls per month, then a $40 monthly minimum (free plan available) | Free tier on signup, then $49 per month for 1,500 credits or $109 once for 1,000 credits (free plan available) |
| 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. | 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 plan | Up to 100 free API calls per month, self-serve, with no card required to start building against the API. | Free credits on signup with access to job search, company search, company lookup, enrichment, exports, and email alerts, at low volume. |
| Free trial | A free tier rather than a time-limited trial, available at sign-up | Not a time-limited trial; a free credit allowance is included on signup |
| 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. | 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 | 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. | 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 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 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. |
| Platforms | REST API, Real-time webhooks, Flat files via AWS S3, Google Cloud Storage, and SFTP, MCP endpoint for AI agents | Web application, REST APIs for jobs, companies, technographics, and buying intents, MCP servers, CSV export |
| Compliance | Data is sourced from public company web pages, news, and filings rather than personal data brokers, European operating base subject to GDPR | Job posting data is published business information rather than personal data, which keeps privacy exposure low, No publicly advertised SOC 2 attestation |

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.
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.

- 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.
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
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.

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.
