Sam Ross is the Co-Founder and CEO of Numeral, an AI-native sales tax compliance platform built for ecommerce and SaaS businesses. He discovered the pain of multi-state tax complexity while running his own eight-figure DTC brands after leaving Airbnb, where he worked in growth under Gustaf Alstromer. That firsthand frustration became Numeral's founding insight. Backed by Y Combinator (W23), Benchmark, and Mayfield, Numeral raised a $35M Series B in September 2025 at a $350M valuation, with over $71M raised in total. The platform processes more than $5 billion in transactions annually, has filed over 150,000 tax returns, and serves 2,000+ businesses including Eight Sleep, Ridge, and Graza.
