TheirStackFinding companies by the technologies they use and the roles they hire. A fit for technical sellers and data teams.
TheirStack turns job postings into signals. It says it processes about 347,000 jobs a day from 370,000 sources, tracks 33,000 technologies across 13M companies, and infers technology use, hiring and buying intent from the postings.
Ranking companies by how closely they match your own customers, learned from your won and lost deals, with the reason on each account.
Ocean is contextual intelligence for go-to-market. It reads what every company actually does from its own website, learns what good looks like from your closed-won and closed-lost deals, and ranks your whole market against it, with the reason behind each score. The ranked accounts arrive in your CRM, your rep queue or your AI agents.
What buyers weigh, grouped by the job each part does. A light blue background marks the stronger side.
| Topic | Ocean | TheirStack |
|---|---|---|
| Finding the right accounts | ||
| Lookalikes | Ocean is stronger here. Core of the product. Segments and models learned from your won and lost CRM deals. | Finds companies by technology and hiring. Its Claude plugin has a skill for finding companies that look like your customers, built on those signals rather than a trained lookalike model. |
| Learns your ICP from won and lost deals | Ocean is stronger here. Learned automatically from your won and lost deals. | You define filters and buying-intent keywords. It doesn’t describe learning fit from your CRM’s won and lost deals. |
| The reason behind each account | Ocean is stronger here. Segment, score, tier and matched signals on every account and every export. | Shows the postings and technologies behind a match, so you can see why a company met your filter. That’s evidence of a technology or need, not of fit with your customers. |
| Coverage | Ocean is stronger here. Segments your whole market and shows win rate, deal size and cycle time for each segment. | About 13M companies, with technology inferred from job postings, so coverage follows who is hiring. |
| Contacts and data | ||
| Contacts | Verified emails and direct phones from a waterfall across 16+ data sources. Charged only when a contact is found, and exports are free. | Company firmographics, job postings and technologies. We found no contact database documented, so teams pair it with an enrichment tool. |
| Technographics from job postings | Answers custom questions about technology from each company’s own website, not from job postings. | Core strength: technology use inferred from millions of postings across 33,000 technologies, including backend tools a website crawl misses. |
| Buying signals | Up-to-date signals built in-house from each company’s own teams, leaders, hiring and website. | Hiring alerts, technology signals and buying-intent keywords across 251M postings, with webhooks for new jobs and companies. |
| Workflow and pricing | ||
| CRM sync | Two-way with HubSpot, Salesforce, Pipedrive and Attio. Reads your deals to learn, then writes scores, segments and signals back. | Exports to CSV and Excel and pushes into your stack, with webhooks, and Zapier, Make, n8n and Databar integrations. |
| AI agents and MCP | MCP server, public API and a chat agent on the same data and lookalike engine. | An MCP server for Claude, Cursor, ChatGPT and other clients over OAuth or an API key, included in every API plan, plus a Claude plugin. |
| Security and privacy | SOC 2 Type II and GDPR, per Ocean’s own site. | We couldn’t open a security page. Ask for its reports and data terms. |
| Pricing | Two ways to buy: a flat-rate plan with credits included, or a custom plan built around your deals and credit volume. | Published. Free credits, then one-time company packs from $109 and monthly API credits from $49, with unlimited seats. |
TheirStack publishes its prices and sells two credit types. Unlimited team members share the credits, and unused credits roll over for 12 months.
Reviewers note that repeat API fetches and webhook events are charged again, and that app exports cap at 200 jobs per company, with fuller history through the API. TheirStack’s FAQ lists a euro starting price that doesn’t match the cards, so use the pricing page. Plan tiers named Starter, Pro and Scale in some write-ups are slider steps, and the $49 step was quoted as $59 in one.

Expect a headline database size, because counts come from its own records and not your market; ask for coverage on your list.
Expect a quote that grows with seats, credits and add-ons, because the entry price is the smallest line; price your real volume.
