Rogo Secures $75M in Series C Funding for AI Finance Platform

Three years ago, two Princeton seniors walked out of investment banking with a thesis, a chip on their shoulder, and a very specific irritation. Gabriel Stengel and John Willett had seen how much institutional finance still ran on human exhaustion, late nights, and manual work disguised as rigor. New York City became the proving ground. Rogo became the bet. Not a chatbot, not a toy, but an AI platform built to speak fluent finance and survive compliance rooms without flinching.

On January 28, 2026, that bet cleared another bar. Rogo raised a $75 million Series C led by Sequoia Capital, pushing the company to a $750 million valuation and more than $165 million raised total. Three years in, and the market is no longer squinting. Sequoia Partner Brian Halligan joined the board, the same Brian Halligan who helped turn HubSpot into a $20-plus billion public company. The signal here is not subtle.

Rogo’s platform is designed for people who bill by the hour and get judged by decimals. Investment banks, private equity firms, hedge funds. The work nobody outside the room ever sees. The models, the memos, the decks that decide whether capital moves or stays frozen. Today, more than 25,000 financial professionals use Rogo daily across over 80 institutions, saving roughly 400 hours per analyst each year. That is not convenience. That is leverage.

Leadership depth matters when money moves at scale. Gabriel Stengel runs the company as Chief Executive Officer, blending computer science with lived Lazard experience. John Willett, now based in London as Chief Operating Officer, is scaling Europe after opening Rogo’s first international office this month. Tumas Rackaitis built the technical core as Chief Technology Officer, grounding the system in a financial knowledge graph that understands what words mean when billions are on the line. Rahul Rekhi joined as President in October 2025, bringing $200 billion in deal experience and U.S. Treasury scars that do not come from theory.

The investor list reads like a closed-door meeting. Henry Kravis. Wells Fargo. J.P. Morgan. Thrive Capital. Khosla Ventures. Tiger Global. This is not curiosity capital. This is conviction capital. The kind that expects results, audits, and scale.

Rogo is not chasing hype. It is chasing accuracy, speed, and trust inside one of the most unforgiving industries on earth. Wall Street does not reward noise. It rewards tools that work when the clock is red and the stakes are real. Watch what happens next, especially now that Rogo has crossed the Atlantic and the expectations just got heavier.
