Datost

Datost is a Y Combinator (Spring 2026 / P26) startup founded by Maceo Cardinale Kwik and Jason Wang. It launched as 'the proactive AI data analyst' - a Slack-native agent with a semantic layer that scored 75.2% on the BIRD-Interact text-to-SQL benchmark versus 33% for a frontier model alone - and has since become an applied research lab building ED1TH, a 25-gram pair of AI AR smart glasses with no cameras, an in-lens display, and a companion smart ring. Backed by Y Combinator and OpenAI.
