XAI Cofounder's Startup River AI Raises $1.1 Billion to Expand Custom AI Tools
The company says its agents now generate more than 50,000 research reports a month for 100+ institutional clients.
- Pinegap secured an $8M Series A round led by Stellaris Venture Partners, bringing total funding to $10.5M. Existing investors Inventus, Silicon Valley Quad, and DeVC participated.
- Institutional equity research analysts tracking 20 to 40 companies must synthesize earnings calls, SEC filings, and internal data largely by hand. CBO Ankit Varmani and Deepak Sharma created Pinegap to automate these workflows.
- Since launching commercially in 2025, the platform deployed more than 1,000 agents across 100+ institutional clients, generating upwards of 50,000 research reports monthly for hedge funds and RIAs.
- Funding will expand the company's GTM and sales capabilities while supporting engineering team growth. Leadership plans to hire former equity research analysts to refine the platform for evolving analyst needs.
- Market opportunity for institutional research represents more than a billion dollars before adjacent expansion. Pinegap expects counter-cyclical positioning during economic uncertainty, as investment firms prioritize products delivering measurable ROI.
