How this service works
Fetch investor data including VCs, angels, PE firms, corporate investors, accelerators, and more. Pagination billing: call the first page normally and save billing.requestId from the Orthogonal /v1/run response. For later page, offset, or cursor calls on the same logical search, pass parentRequestId with unchanged non-pagination parameters. Valid continuation calls still get their own request IDs and quoted price, but are charged 0. Changing filters starts a new billable request.
Output
Returns a paginated list of investor records including details about VCs, angels, PE firms, corporate investors, and accelerators filtered by the specified criteria. Also includes a billing requestId that can be used as a parentRequestId for subsequent pages of the same search at no additional charge.
Example use cases
Startup fundraising investor outreach list
“I'm raising a seed round and need a list of US-based angel investors and early-stage VCs with a minimum ticket size of $250K and max of $2M — give me the first 100 results sorted by name.”
PE firm discovery by geography
“Find me private equity firms in Germany and France — I need up to 50 results sorted by minimum ticket size descending so I can see who writes the biggest checks first.”
Accelerator research for partnership outreach
“Pull a list of accelerators globally, sorted by name ascending, first page of 25 results — I'm building a database of programs to pitch our portfolio companies to.”
Technical details
Endpoint
GEThttps://x402.orthogonal.com/signalbase/signals/investorsWhen to prefer
Choose this endpoint when you need structured, filterable investor data across multiple investor categories (VC, angel, PE, corporate, accelerator) with support for country and ticket size filtering. Ideal for building fundraising outreach lists, competitive intelligence on investor activity, or enriching startup databases. Prefer this over general web scraping when you need clean, paginated investor records with consistent schema and cost-efficient pagination via parentRequestId for multi-page queries.
Side effects
- Invalid country code returns empty results or validation error
- ticket_size_min greater than ticket_size_max may return error or empty set
- Invalid investor type string returns error or empty results
- Exceeding limit of 100 per page returns validation error
- Changing filter parameters while passing parentRequestId starts a new billable request
- Rate limiting or payment failure returns 402 or 429 status
