Decagon: $250 Million Series D At $4.5 Billion Valuation Raised For AI-Based Customer Experience Platform

By Amit Chowdhry • Jan 29, 2026

Decagon, a company focused on conversational AI agents for concierge-style customer experiences, has raised $250 million in a Series D round led by new investors Coatue Management and Index Ventures. The financing also included new participation from ChemistryVC, Definition Capital, and Starwood Capital, alongside existing backers a16z, A*, Accel, Avra, Bain Capital Ventures, Elad Gil, T.Capital, Forerunner, and Ribbit Capital.

The company said the round triples its valuation over the past six months to $4.5 billion, following a growth-heavy 2025 in which it signed more than 100 new enterprise customers and expanded deployments across consumer-facing sectors, including travel and hospitality, financial services, health and wellness, and online retail. Decagon is positioning its platform as an alternative to legacy customer service and relationship tools, arguing that businesses are moving beyond configuration-heavy systems toward AI-driven, personalized interactions delivered at scale.

Decagon’s pitch centers on what it calls “AI concierge” experiences across channels such as voice, chat, email, and SMS. The company says it helps customer experience, product, and engineering teams launch AI agents using “Agent Operating Procedures,” which pair natural-language direction with code-level controls to ensure safety and speed. Decagon also reported average deflection rates exceeding 80%, framing that metric as evidence that automation can scale while maintaining quality.

The company’s customer list spans major consumer brands and digital-first financial services players. In travel and hospitality, it cited names including Avis and Budget, Hertz, Away Travel, Kindred Rentals, Easy Park, Contiki Group Tours, and Duolingo. In financial services, it cited Block, Affirm, Chime, Varo Bank, Betterment, Carry, Wealthsimple, Bilt, Figure Lending, and Monarch Money. In health and wellness, it cited Oura Health, Noom, Nourish, ClassPass, SimplePractice, Spring Health, Brightside Health, and Eight Sleep. In retail and consumer, it cited Mercado Libre, Hunter Douglas, 1-800-FLOWERS.COM, Ritual Cosmetics, Quince, Fi Smart Collar, and Curology. In commerce and connectivity, it cited Deutsche Telekom, Grubhub, GoPuff, Fanatics Collective, Little Spoon, Misfits Market, and Flashfood.

Decagon also described its customer base as spanning a wide range of AI maturity levels. It said roughly a third of customers had no prior AI automation, while more than half replaced legacy infrastructure such as IVRs, ticketing tools, or CRM-based agents, and a smaller share chose Decagon over building internally. The company added that most customers evaluated multiple AI options and concluded that configuration-driven approaches did not deliver the true concierge experience.

With the new capital, Decagon is leaning into a broader narrative that customer experience AI is shifting from a narrow efficiency initiative to a strategic, revenue-linked platform decision. The company described board-level interest that extends beyond cost reduction to include brand trust and differentiation, while emphasizing operational use cases aimed at faster resolutions and better frontline support.
