About
Gaus (now operating as Astor) is an AI investment advisor platform founded in 2025 by Bruno Koba (ex-Nubank, Stanford GSB) and Daniel Tulha Hochstetler. The platform connects to users' brokerage accounts via Plaid bank-level security, analyzes their actual holdings, and delivers personalized investment guidance through a conversational AI interface available via text or call 24/7. Astor is an SEC-registered investment advisor built with bank-grade encryption and compliance at its core. The company was part of Y Combinator's S25 batch and rebranded from Gaus to Astor in January 2026, targeting retail investors who want specific, data-driven advice based on what they actually own rather than generic financial content.
