How this service works
TheirStack — Search companies by firmographics (industry, country, employee count, revenue, funding stage), tech stack (`company_technology_slug_or` — case-sensitive slugs from theirstack/tech-catalog), and hiring signals (`job_filters` + `min_num_jobs_found`: companies actively hiring for given roles/techs). REQUIRED: `limit` (1-5, vendor bills per company returned); `page` for more. Returns companies with the matching jobs/technologies attached — built for ABM, lookalike discovery, and compet…
Output
Returns a list of matching companies (up to the requested limit) with attached firmographic data (industry, country, employee count, revenue, funding stage), the specific technologies they use, and the job postings that triggered the hiring signal match — structured for ABM workflows and sales prospecting.
Example use cases
ABM target list for sales outreach
“Give me up to 5 Series B fintech companies in the United States with between 50 and 500 employees that are actively hiring sales roles — I want to build a target list for outbound.”
Lookalike company discovery for expansion
“I have a customer that's a mid-sized e-commerce company using Shopify in the UK — find me 5 similar companies with comparable size and tech stack on page 1 so I can identify new prospects.”
Competitive landscape research by tech stack
“Find me up to 5 companies that use both Snowflake and dbt in their stack, are in the data analytics industry, and have more than 200 employees — show me page 1.”
Technical details
Endpoint
POSThttps://vaaya.ai/api/run/theirstack/companiesWhen to prefer
Choose this endpoint when you need to discover or filter companies based on a combination of firmographics, technology adoption, and hiring activity — especially for ABM campaigns, sales prospecting, or competitive research. It is distinct from individual company tech lookup (which gives you technologies for a known company) because it works in the opposite direction: finding unknown companies that match your criteria. Prefer this over generic web search when you need structured, filterable B2B company data with hiring signals.
Side effects
- Invalid or non-lowercase technology slug (slugs are case-sensitive from theirstack/tech-catalog)
- limit exceeds maximum of 5, returning an error
- No companies match the combined filters, returning empty results
- Malformed job_filters object causing a 400 error
- Payment failure via x402 protocol preventing request execution
