Afthonea

We’re building the first autonomous insurance group, starting with Morrow, our AI-native commercial insurance brokerage. We help businesses find, compare, and buy insurance across 100+ carriers. Every placement deepens our understanding of businesses, risk, and underwriting. We’re turning that knowledge into an insurance ontology that gives our AI agents the context to reason, apply judgment, and execute insurance workflows autonomously across calls, emails, and carrier portals. Our ambition is to build the most comprehensive intelligence layer in the industry. Over time, we’ll use this foundation to develop and underwrite our own insurance products. Insurance spending represents 12% of U.S. GDP, and we want to go after all of it. We’re backed by C-suite executives at some of the world’s largest insurers, first-check investors in Rippling and Twilio, and a Cloudflare board member.
