Angel & Advisor with 20+ years of AI expertise, passionate about guiding early-stage startups. I thrive on AI research —from loss functions and optimizers to predictive modeling and recommendation systems. I'm not looking for startups primarily integrating APIs and marketing them as AI solutions.

Early-stage startups with bold ideas and exceptional teams.

Experienced in building, scaling, and exiting AI startups rooted in genuine R&D—no API resellers.
