Y Combinator
(https://ycombinator.com) 📸 Data Snapshot: June 20, 2026Inspect the JSON-LD. Is there an Organization or Person schema, and does it carry sameAs links to real external profiles (LinkedIn, socials)? Missing schema or no identity declaration signals an anonymous entity.
The only minor gap is a technical one; the homepage lacks schema_json (JSON-LD) despite claiming industry-leading status. However, the expert footprint is massive, with every partner listed with a verifiable history, such as Garry Tan (Posterous, Initialized Capital) and Tom Blomfield (Monzo). These authorities are household names in the tech industry, though connecting them via Person schema would further reduce the gap.
There is no disconnect between marketing claims and demonstrated performance. The site lists a combined valuation of $1.3 Trillion and backs it with a massive directory of named companies including Stripe ($107B), OpenAI ($500B), and DoorDash ($39B). These are not vague assertions of success but publicly documented financial outcomes.
Identity & Authority is read from the structured data first: whether the site declares who it is in machine-readable schema, with verifiable identity links. Below is the schema captured per page, then the external proof links that support (or fail to support) that identity.
