Beatdapp Went Looking for Missing Royalties - and Found a Fraud Economy Hiding in the Stream
The founders thought music services had an accounting problem. The data pointed to something stranger: bots, click farms and stolen accounts competing with real listeners for a finite royalty pool. Beatdapp built the referee - then widened the field.
Multifactor
Multifactor is a San Francisco cybersecurity startup, part of Y Combinator's Fall 2025 batch, that lets people and AI agents access online accounts without ever exposing the underlying passwords. Using patented post-quantum cryptography, it turns any account - a bank, an inbox, an internal tool - into a shareable, revocable 'read-only' link, the way Google Docs shares a document. Founded by former CIA cyber officer Vivek Nair and ex-NASA cryptographer Colin Roberts, the company raised a $15M seed round in December 2025 led by Nexus Venture Partners.
