Stanley Wei is the CEO and co-founder of Pine AI (19pine.ai), a San Francisco startup building an autonomous AI agent that fights consumers' customer-service battles for them: negotiating bills, cancelling subscriptions, disputing overcharges, and chasing refunds through real phone calls and emails. A former Chief Strategy and Operating Officer at Nasdaq-listed Agora and a former investor at Hillhouse Capital, Wei founded Pine in late 2024 after a $200 dispute with his bank ate up 90 minutes of his life. Pine raised a $25 million Series A in December 2025 and reports more than $37 million in consumer savings.
Pine AI is an autonomous consumer AI agent that handles the tedious 'digital chores' people hate - negotiating bills, canceling subscriptions, filing complaints, and chasing refunds. Instead of just answering questions like a chatbot, Pine actually places phone calls, sends emails, and navigates websites to get things done on a user's behalf. Founded in 2024 by former Agora executives Stanley Wei and Vincent Sun, the Palo Alto company reports a 93% negotiation success rate and has saved consumers over $3 million. It raised a $25 million Series A in December 2025 led by Fortwest Capital.
