[KG] Y Combinator — momentum
Y Combinator is doubling down on AI startups that directly challenge incumbents. Recent portfolio moves include Onyx—an open-source enterprise search tool taking on Glean's $7.2B valuation—and Aviary's autonomous AI sales agent. Ava raised $36M for a fully AI sales rep, while Composio launched a secure credential platform. These bets signal YC's strategy of funding direct competition against established players. Yet the accelerator also faced a credibility hit: it removed AI startup Delve from its website after allegations of open-source license stripping. Partner Cumulus Labs joined recently, but the Delve incident raises questions about YC's due diligence. With Garry Tan at the helm, YC is shipping fast—but can it sustain quality control while backing so many aggressive AI plays?
