Truffle (now operating as Marble) is a New York-based Y Combinator S26 startup building an AI-native operating system for the restaurant back-of-house. It replaces the patchwork of spreadsheets, clipboards and disconnected point solutions that restaurants, cafes and bars rely on with a single system: computer vision and voice AI capture real-time inventory levels, machine-learning models forecast item-level demand, and AI agents run end-to-end workflows like procurement, invoice reconciliation, scheduling, food prep and menu engineering. Founded by Aakar Khanna (CEO) and Arjun Chaliha (CTO), it targets the billions the hospitality industry loses each year to stockouts, food waste and lost profit.
Jake Sussman is the cofounder and CEO of Marble Health, a virtual behavioral health company that embeds inside American schools to get anxious, depressed and overwhelmed kids into group therapy within days rather than months. He helped build Headway into a mental-health unicorn, then walked away to teach fifth-grade English at a Brooklyn charter school, where one overstretched counselor for hundreds of students convinced him the youth side of the system was broken. In 2023 he founded Marble with fellow Headway alum Dan Ross, betting that insurance-funded virtual group therapy, routed through school counselors, could scale care without waitlists. By late 2025 Marble had run more than 15,000 sessions and raised a $15.5M Series A led by Costanoa Ventures.
