How this service works
Search for investors with flexible filtering capabilities 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
A list of investor profiles matching the specified filters, including verified contact details such as email addresses and phone numbers, LinkedIn profile URLs, investment stage preferences, sectors of interest, fund information, and geographic focus areas.
Example use cases
Angel investors for pre-seed fintech round
“Search for angel investors actively funding fintech startups in pre-seed and seed stages. I need ones based in major US tech hubs like San Francisco and New York with verified contact info so I can start my outreach campaign.”
Climate tech VCs with European presence
“Find venture capital firms investing in climate technology and clean energy companies across Europe. Filter for investors who lead Series A and B rounds, and get me their contact details and fund information.”
Healthcare innovation investors by geography
“Show me investors focused on healthcare innovation and biotech across the US and Canada. I'm looking for early-stage backers, and I need their email addresses and LinkedIn profiles to start building relationships.”

Endpoint
POSThttps://mpp.orthogonal.com/fiber/v1/investor-search?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to search and filter a large database of investors by multiple criteria (location, stage, sector, fund size) and require verified contact information. Prefer this over person or company search when the specific use case is fundraising outreach or investor prospecting, as it is tuned to investment-specific attributes and filters.
