# Gabriel Stengel

A 2020 Princeton computer science graduate who did stints at J.P.

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.
