Spiros Xanthos, Resolve AI: The Greek founder building the future of intelligent software

“Success isn’t about raising money — it’s about building something people actually want to use.”

In this episode of The Outliers Podcast, Spiros Xanthos, founder and CEO of Resolve AI, shares his journey from founding early-stage startups in Greece to leading cutting-edge AI ventures in the U.S.

Spiros began his entrepreneurial path driven by curiosity and a love for building products people actually want to use. Over the years, he’s launched and exited multiple companies, learning firsthand that risk is the ultimate teacher: “We owe it to ourselves to take more risks — and the earlier we do it, the better we learn how.”

Today, with Resolve AI, he’s applying that same mindset to artificial intelligence. The company is building AI agents that help software engineers automate repetitive work so they can focus on creativity and innovation. For Spiros, AI isn’t a threat — it’s a tool that will elevate human potential. “Historically, what improved human life wasn’t politics or luck. It was technological progress.”

Through failures, pivots, and breakthroughs, Spiros has stayed true to one principle: success isn’t about raising capital, it’s about creating real value. His story is a testament to taking ownership, pushing limits, and believing in technology’s power to make life better.
