How this service works
Returns the Portfolio Companies found on the portfolio pages of thousands of VCs, accelerators, and incubators, as a list of Connections categorized as `investor`, ordered by the `first_seen_at`, descending.
Output
Returns a paginated JSON object containing a list of Connection objects categorized as 'investor', each with a UUID, context describing the investor-startup relationship, source URL, first_seen_at and last_seen_at timestamps, and related company details (name, domain, ticker) for both the investor and the portfolio company. Meta includes record state and schema version; if page parameter is provided, also includes total count.
Example use cases
Track newly funded startups this quarter
“Show me all portfolio companies that were first seen on VC or accelerator portfolio pages since October 1, 2024 — give me up to 100 results on page 1.”
Monitor recent investor-startup relationships
“Get all investor connections that were last seen after September 1, 2024 and first seen before December 31, 2024, paginate to page 2 with 30 results per page.”
Build a startup discovery feed
“Fetch the newest portfolio companies added to VC and incubator pages — first seen from 2024-06-01 through 2024-12-31, limit to 200 results.”
Technical details
Endpoint
GEThttps://agents.predictleads.com/api/v3/discover/portfolio_companies/connections?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need broad, cross-VC discovery of portfolio companies across thousands of investor pages rather than targeting a specific company's connections. It is ideal for building startup databases, tracking market activity, or monitoring which new startups have been added to VC portfolios within a given date range. Use the date filters to narrow to recent additions for freshness-sensitive use cases.

- Requesting a page beyond available results returns an empty data array
- Missing or invalid authentication returns a 401 or 402 error
- Limit exceeding 1000 returns a validation error
- Rate limiting may return a 429 error for excessive concurrent requests
