Transient.AI
Transient.AI is a New York-based fintech startup building what it calls a Trusted AI Operating System for capital markets - a compliant, explainable intelligence layer that unifies fragmented legacy systems for hedge funds, asset managers, RIAs, and sell-side trading desks. Founded by former traders and technologists from Goldman Sachs, Credit Suisse, UBS, and McKinsey, the company ships a suite of enterprise SaaS platforms (Caddie.AI, ClarityRIA, CapFlo.AI, Sales+) plus specialized AI agents for trade ideas, surveillance, AML, and term sheets. In May 2026 it raised its Series A led by NEXT Investors to scale deployment inside regulated financial institutions.
Gabriel Stengel
Gabriel Stengel is the co-founder and CEO of Rogo, a generative AI platform built for investment banks, private equity firms and hedge funds. A 2020 Princeton computer science graduate who did stints at J.P. Morgan and whose co-founder came from Lazard, Stengel turned a clunky senior-thesis econometrics chatbot into a company that, by April 2026, raised a $160 million Series D at a roughly $2 billion valuation. Rogo's AI agent Felix now serves more than 35,000 finance professionals across 250-plus institutions, automating the grunt work of benchmarking, earnings analysis and pitch decks that once kept junior bankers awake at night.
