Fatima Husain
Fatima Husain is the Chief Business Officer at Numeral, a San Francisco-based AI-powered sales tax automation platform that raised $35M in Series B funding (led by Mayfield) at a $350M valuation in September 2025, bringing total funding to roughly $57M. By that round Numeral had processed $5B+ in transaction volume, filed 150,000 returns, tripled revenue year over year, and served 2,000+ ecommerce and SaaS brands across 11,000+ jurisdictions - and has since expanded into international VAT/GST compliance across 70+ countries. A Yale-educated operator-turned-investor originally from India, she spent six years leading growth and product at Airbnb - achieving 20x+ YoY growth on the supply side - before co-founding Mosaic General Partnership (formerly Mastry Ventures) with NBA champion Andre Iguodala. She was an early angel investor in Numeral and joined as CBO to build again, bringing two decades of operational instincts and venture capital pattern recognition to one of fintech's most unsexy yet massive problems.
