The round was led by Lightspeed Venture Partners to tackle the fundamental limitation preventing AI agents from transforming enterprise workflows: they don't learn from experience.

Several industry leaders also participated in the round, including Guillermo Rauch (Vercel CEO), Dharmesh Shah (HubSpot CTO & Founder), Gokul Rajaram, and Soham Mazumdar (Rubrik Co-founder), alongside institutional investors SV Angel, Blitzscaling Ventures, Operator Partners, and Agent Fund by Yohei Nakajima. Existing investors Elevation Capital and Together Fund also participated, bringing the total funding to $29 million.
