TheirStack Alternative for Job Posting Data
TheirStack and JobDataLake overlap on the data but diverge on the product. TheirStack turns job postings into technology and hiring signals for B2B prospecting — the answer is a company. JobDataLake serves the postings themselves as structured records — the answer is a job. Pick by which one your product displays to its user.
What TheirStack is
TheirStack is a technology-hiring-signal product: it parses postings to infer what a company uses and who it is hiring, aimed at sales prospecting and market intelligence.
TheirStack vs JobDataLake
| TheirStack | JobDataLake | |
|---|---|---|
| What you get back | Companies, filtered by the technologies and roles they are hiring for. | Job postings, filtered by title, skills, salary, seniority, location, remote type, and date. |
| Best-in-class at | Tech-stack extraction and buying-signal detection from posting text. | Normalized job fields — salary in USD, skills, seniority — across the whole corpus. |
| Freshness | Postings indexed within hours for major sources. | Scraped directly from 25,000+ company career pages and 40+ ATS platforms, updated hourly. New postings are typically searchable within 3 hours. |
| Coverage shape | Deep on technology companies, which is what the use case needs. | Broad across industries and geographies: 1.8M+ listings from 25,000+ companies. |
| API | Clean REST, filters oriented around technology and company. | One REST endpoint with 15+ filters, X-API-Key auth, flat JSON. Skills filter in AND mode. Also available as an MCP server for AI tools. |
| Pricing model | Usage-based tiered plans. | Credit-based and public: 1,000 free credits at signup, then $50 / 100k, $200 / 1M, $400 / 4M credits. One credit = one request. Credits never expire and no fields are gated behind a higher tier. |
When to pick TheirStack instead
- You are building GTM tooling and the output is a list of accounts to go sell to.
- Technology detection — "who is hiring Rust engineers" — is the core feature, not a byproduct.
- You care about the signal a posting represents more than about the posting itself.
When to pick JobDataLake
- You display, store, or search individual job listings — a job board, a career tool, an AI assistant.
- You need broad industry coverage, not just technology employers.
- You want salary normalized to USD and skills queryable in AND mode across every posting.
Frequently asked questions
Can JobDataLake be used for hiring signals and GTM prospecting?
Yes — postings are queryable by company, role, skills, and date, which is enough to build hiring-signal workflows. What JobDataLake does not do is pre-package technology inference the way a purpose-built signals product does.
Which has better coverage?
It depends on the segment. TheirStack is deliberately deep on technology employers. JobDataLake indexes 1.8M+ listings from 25,000+ companies across industries and geographies, which is broader but not specialized toward tech-stack detection.
Can I try it before paying?
Yes. A free API key includes 1,000 credits with no credit card, and the MCP server is free for 500 searches a day with no signup at all.
