Ciro is building AI agents for sales prospecting. Today, founders and sales reps spend 30%+ of their time manually searching, qualifying, and engaging leads. Ciro makes prospecting on platforms like LinkedIn 10x easier by automatically scanning profiles, qualifying them, and enriching them.

Ciro is a tight-knit team of engineers, sales execs, and product managers with experience from Meta, Stanford, Google and Bain & Co. Two of the founders served as VPs of Sales at high-growth SaaS startups and understand our domain deeply. We are cash flow positive and are backed by some of the best investors in the world, including Y Combinator, SV Angel, CRV, and the founders of Flexport, BuildZoom, and Tegus.
