Sol raised $4 million in a round led by General Catalyst and Nexus Venture Partners, with participation from DeVC, Peercheque and Kunal Shah. The financing accompanies its emergence from stealth.

The company had more than 100 pre-launch users and is opening access through a waitlist. Proceeds support research and development, go-to-market work, LLM processing and tooling, hiring and customer work across geographies.

Sol detects commitments in Gmail and prepares follow-up research, documents, replies and meeting proposals. Users approve prepared work before anything is sent, scheduled or shared.
