The cheapest TheirStack plan is Free, with 200 API credits a month. The cheapest paid API plan is $49 a month for 1,500 credits. At 1M job postings a month the price is $1,500 (TheirStack pricing, September 2026).
The page marks no "most popular" tier, so we name none. For companies and tech stacks, 1M records is 3M credits. TheirStack lists no 3M tier, only 2M at $2,300 and 5M at $5,500.
TheirStack sells job postings, company firmographics and technographics. We found no people or contact records, so pair it with a contact source.
Plans
TheirStack has three products with separate prices: API plans, app credit packs and datasets. Every plan can be cancelled any time. The pricing page shows monthly figures only, with no billed-yearly figure for the API plans.
| Plan | Price | Credits | Seats | API access | Limits |
|---|---|---|---|---|---|
| Free | $0 | 200 API credits and 50 company credits a month | 10 invitations | Yes, on the free tier | 4 a second, 10 a minute, 50 an hour, 400 a day. 25 results a page, 5 pages |

Source: TheirStack pricing and plans docs, checked September 2026. Every API plan includes the Job Search, Company Search, Technographics and Buying Intents endpoints, webhooks and an MCP server.
Per 1,000 credits the price falls from $32.67 at 1.5k to $1.50 at 1M and $1.10 at 5M. A paid account keeps the free 200 API credits and 50 company credits a month (TheirStack plans, September 2026).
App packs are one-off. Pack prices are $109 (1,000), $199 (5,000), $299 (10,000), $399 (20,000), $549 (50,000), $749 (100,000) and $999 (200,000). A monthly subscription is 10% cheaper (TheirStack pricing, September 2026).
Datasets are a third product. The jobs dataset ships as CSV or Parquet over S3 (TheirStack datasets docs, September 2026). The pricing page shows no dataset price, so ask TheirStack for one. Datasets suit batch loads.
What a credit buys
An API credit is spent per record returned, or per webhook event sent. A company costs three times a job. Credits are used only when data comes back.
| Action | API credits | Source |
|---|---|---|
| Job returned by Job Search | 1 per job | TheirStack credits docs |
| Job sent in a job.new or job.closed webhook | 1 per event | TheirStack credits docs |
| Company returned by Company Search | 3 per company | TheirStack credits docs |
| Company sent in a company.new webhook | 3 per event | TheirStack credits docs |
| Technographics lookup (all technologies of one company) | 3 per company | TheirStack credits docs |
| Count with include_total_results and limit 1 | 1 for a job, 3 for a company, 0 if nothing matches | TheirStack count docs |
| App reveal or export of a company | 1 company credit | TheirStack credits docs |
All sources checked September 2026. One credit is one job. One company or one tech stack is three credits, so 1,500 credits buys 1,500 jobs or 500 companies.
Hidden costs
- Companies and tech stacks cost 3 credits. A company workload needs three times the credits of a job workload at the same record count (TheirStack credits docs, September 2026).
- Repeat requests are billed again. Asking for the same data twice spends credits twice (TheirStack credits docs, September 2026).
- A count is not free. A count that matches anything returns one record and spends 1 credit for a job or 3 for a company. Zero matches cost nothing (TheirStack count docs, September 2026).
- Credits are prepaid. TheirStack does not meter usage and invoice it later at any volume. Auto recharge buys credits at the same plan prices as your balance runs down (TheirStack auto recharge docs, September 2026).
- Paid accounts run at 4 requests a second. Free accounts also get 10 a minute and 400 a day (TheirStack rate limit docs, September 2026).
- Credits expire 12 months after purchase. Unused credits roll over until then, and cancelling does not end that window (TheirStack refund docs, September 2026).
- Refunds are narrow. You get one only if no credit from the invoice was used and you ask within 90 days. Card fees of about 3% are deducted (TheirStack refund docs, September 2026).
- App exports cap at 200 jobs a company. A full job history needs the API, webhooks or MCP, billed in API credits (TheirStack credits docs, September 2026).
- Above 5M credits there is no public price. TheirStack prices that tier per deal (TheirStack pricing, September 2026).
Worked examples
One record is one job posting at 1 credit, or one company or tech stack at 3 credits. Prices are USD list. TheirStack buys one tier per month, so we use the smallest published tier that covers the credits.
10k records a month
- 10k jobs: 10,000 credits. The API 10k tier is $169 a month.
- 10k companies or tech stacks: 10,000 x 3 = 30,000 credits. The 20k tier is too small, so the API 50k tier at $400 a month applies. The other 20,000 credits roll over.
- App packs: 10,000 company credits is $299 one-off.
- LeadOcean Pro: $499 flat. At 10k, TheirStack is cheaper if you need job postings or tech stacks and no contacts.
1M records a month
- 1M jobs: 1,000,000 credits. The API 1M tier is $1,500 a month, or $1.50 per 1,000.
- 1M companies or tech stacks: 1,000,000 x 3 = 3,000,000 credits. No 3M tier exists, so the next published tier is API 5M at $5,500 a month. We do not multiply a per-credit rate to a price for 3M.
- Rate: 1,000,000 jobs at 500 a page is 2,000 requests, or 500 seconds at 4 a second.
- App packs: the largest pack is 200,000 company credits at $999. No app price exists for 1M.
- LeadOcean Pro: $499 flat. Exports run up to 50,000 rows per request and 500,000 rows a day, so 1M rows is 20 requests over two days.
25M records a month
- 25M jobs: 25,000,000 credits. That is above the 5M tier, so the price is per deal. There is no public 25M price.
- 25M companies or tech stacks: 75,000,000 credits. Also per deal.
- Rate: 25,000,000 jobs at 500 a page is 50,000 requests, or about 3.5 hours at 4 a second.
- TheirStack says a flat-rate dataset is often cheaper than credits at this volume (TheirStack pricing, September 2026).
- LeadOcean Pro: $499 flat. 25M is past the 10,000,000 export ceiling per period. A very large month is paced down to one request a minute past the fair-usage line, not cut off. One email to support gets more headroom.
TheirStack wins on price for job postings at 1M a month. LeadOcean wins on a flat bill for contact records, not job postings.
Is it worth it
TheirStack is worth it when job postings or hiring signals drive your list. It is a signal source, not a contact database.
- Founder or analyst testing a signal: Free. 200 API credits is 200 jobs or 66 companies a month.
- Sales team building lists from hiring data: App packs. 10,000 company credits is $299 one-off, with no monthly commitment.
- Developer feeding jobs to a pipeline or agent: API 10k at $169 or API 100k at $600. Webhooks and MCP are in every API plan.
- Data team at 1M jobs a month: API 1M at $1,500. Consider a dataset above that, and ask for the price.
- Buyer who needs verified emails or phones: Not TheirStack. Look at the contact tools in TheirStack alternatives.

Alternatives with a different price model
These three charge by plan tier or a flat fee, not by a per-record credit.
BlitzAPI: flat monthly fee. Core is $399 a month for everything except verified emails and phones. Plus is $499 and adds verified work emails. Full is $599 and adds US phone numbers. One result is one company, person, email, phone or job posting, and the data includes 100M+ job postings (BlitzAPI pricing, September 2026, BlitzAPI docs, September 2026). Accounts opened by September 30, 2026 kept 15M results a month under fair use. For newer accounts BlitzAPI publishes 5 requests a second and no monthly volume.
BuiltWith: subscription tiers. Basic is $295 a month, Pro $495 and Team $995. (BuiltWith plans, October 2026). It covers technology profiles, not job postings. It publishes no price at 1M.
LeadOcean: flat fee. Free is 1,000 records one-off with no card. Pro is $499 a month with unlimited searches, enrichments and lookups, 100 requests per second per key and 5 API keys. There are no credits and no overage invoice. It filters 105 technology categories across about 7.8M crawled sites, over 693M people and 63M companies, through REST and MCP. See pricing.
