Ali Hussain is the CEO and co-founder of Tabs, a New York based startup building AI agents that automate the messy contract-to-cash side of B2B finance: billing, collections, and revenue recognition. He founded the company in 2023 after watching accounts receivable break at scale as COO of Latch (later DOOR), and earlier worked at Boston Consulting Group, Google, and the U.S. Congress. In September 2025 Tabs raised a $55M Series B led by Lightspeed Venture Partners to launch its first Billing and Collections agents, bringing total funding to roughly $92M.
Tabs is an AI-native revenue platform that automates the contract-to-cash cycle for B2B finance and accounting teams. Its AI agents read messy customer contracts, generate and send invoices, chase collections, reconcile payments, and handle revenue recognition - turning manual back-office work into software. Founded in 2023 in New York by operators from Latch, Tabs serves 200+ customers including Cursor and Statsig, and raised a $55M Series B led by Lightspeed in September 2025, bringing total funding past $91M.
