AI Startup Decagon Hits $4.5B Valuation
AI-native startup Decagon has completed its first tender offer at a $4.5 billion valuation. The event signals robust investor appetite in the private markets for scalable enterprise AI infrastructure platforms, even as the broader venture market remains cautious.
The tender offer follows a $250 million Series D funding round in January 2026 that first established the $4.5 billion valuation. New investors Coatue Management and Index Ventures led the round, with continued support from existing backers like Andreessen Horowitz and Accel. Founded in 2023 by CEO Jesse Zhang and President Ashwin Sreenivas, Decagon develops AI agents for automating enterprise customer support. The platform is designed to handle complex tasks like processing refunds and canceling subscriptions, moving beyond simple chatbot interactions. Both founders have previous startup success; Zhang sold his gaming startup Lowkey to Niantic, and Sreenivas sold his computer vision startup Helia to Scale AI. Zhang, a Harvard computer science graduate, previously worked at Google and Citadel, while Sreenivas, a Stanford computer science alum, worked at Palantir. Decagon's platform utilizes large language models from providers like OpenAI to offer autonomous support across chat, email, and voice channels. The company reports that its AI can handle a significant percentage of customer interactions without human intervention, with one major client seeing 91% of its global support automated. The company has seen rapid growth, reportedly reaching eight-figures in annual recurring revenue within its first year. High-profile clients include Duolingo, Notion, Hertz, Block, and Deutsche Telekom. This employee liquidity event is a key strategy for retaining talent in a competitive market for AI expertise, allowing early team members to realize financial gains without waiting for an IPO. The participation of Series D investors in the tender offer signals strong insider conviction in the company's future growth.
