Agents will search the web more than humans this year. Soon it will be orders of magnitudes more. Nearly every meaningful AI workflow, from coding agents to research systems to enterprise copilots, depends on external information as a core input. For accurate and fast web search, leading AI companies and enterprises rely on @ExaAILabs. @WilliamBryk and @jeffzwang started building search from the ground up in their Harvard dorm. 5 years later they're becoming the default for developers (and agents) in the AI era. Thrilled to be leading Exa's Series C and to back Will and Jeff as they build perfect web search for the age of intelligent agents. More on why @JenniferHli @steph_zhang @JasonSCui and I invested in the comment link.

It’s been amazing watching this journey.

From metaphor systems to crashing on the company couch. Talking about A100s and rag talks.

Congrats team.
