Our verdict on TheirStack
TheirStack is a company intelligence platform for sales, marketing, and research teams that need account lists shaped by technology adoption, hiring activity, firmographics, and buying intent. Company profiles combine firmographic, financial, technographic, and hiring data, while search supports technology stacks, hiring signals, and firmographic criteria. Teams can enrich company lists through CSV upload, manual input, or API, then export results to CSV or Excel. Job search covers real-time and historical postings, giving the product a clear emphasis on company research and prospecting.
Pricing is split between one-time company-credit packages and a monthly API plan. The 1,000 Company Credits package costs $109, followed by 5,000 for $199, 10,000 for $299, 20,000 for $399, 50,000 for $549, 100,000 for $749, and 200,000 for $999. Each company-credit plan provides access to job postings, technologies, and firmographics, with unused credits rolling over for 12 months. The 1,500 API Credits plan costs $49 per month and includes Job Search, Company Search, Technographics, and Buying Intents endpoints, plus webhooks, an MCP server, and unlimited team members.
Its ecosystem supports Clay, LinkedIn Audiences, Make, n8n, and Zapier, alongside API, webhook, and workflow-based enrichment. Webhooks can notify teams about new jobs, closed jobs, and new companies, while the MCP server connects the product to AI assistants. Technographics include confidence scores and first- and last-seen dates, adding context to technology signals rather than presenting only a technology label. TheirStack suits teams building technology- or hiring-led account lists and automated research workflows. Buyers seeking a broader account-intelligence focus should compare how well this signal-centered approach matches their needs.
