Sol, founded by Anish Karan, Prateek Srivastava and Ranjith Nair, has emerged from stealth with $4 million led by General Catalyst and Nexus Venture Partners. Its assistant reads Gmail for commitments and starts the work, adding to a small but growing set of Indian-founded agentic AI startups.
Sol, a startup building a proactive AI assistant for email-heavy professionals, emerged from stealth on 23 September 2026 with $4 million in funding. General Catalyst and Nexus Venture Partners led the round, with DeVC, Peercheque and CRED founder Kunal Shah also investing.
The company was founded in August 2025 by Anish Karan, Prateek Srivastava and Ranjith Nair. Karan is its CEO. The announcement was made through a Business Wire release from Sol Foundry Inc., datelined San Francisco.
What the money is for
Sol will spend the funds on research and development and on go-to-market work. The R&D budget covers LLM processing and tooling costs, hiring, and working with customers in different markets. The product is currently available through selective access while the company prepares a wider release.
How Sol works
Sol connects to a user's Gmail and looks for commitments, which it calls open loops, without the user having to tag, forward or file emails. When it finds one, it begins the work needed to fulfil it. A promise to send an analysis can trigger research and a draft document; agreeing to sync with someone can lead to a proposed meeting. It can also build presentations and draft replies.
The assistant runs in a dedicated computer environment and can use a browser to work across tools, drawing on a library of more than 100 skills. Nothing is sent, scheduled or shared until the user approves it. The company says customer data is not used to train AI models.
Karan told Indian Startup News that people should not have to become AI experts to benefit from the technology. Nexus partner Jishnu Bhattacharjee said Sol is building AI that “just knows when to act and proactively does the right things.”
Who it is for
Sol is aimed at people whose work runs through large volumes of email: founders, executives, and professionals in sales, marketing, consulting, recruiting and agencies.
It enters a growing agentic AI segment in India. Indian agentic AI startups raised about $60 million in the first four and a half months of 2026, against $144 million in all of 2025, according to Startup Story. Other funded players include Composio, which raised a $24 million Series A, and Kapture, which raised $10 million in a pre-Series B round.
