Decagon AI is a startup dedicated to developing AI-powered customer service agents for enterprises. Within 12 months, the company completed its third major financing round and successfully raised $131 million today.

The C-round valuation reached $1.5 billion, led by venture capital firms Andreessen Horowitz and Accel, with participation from existing investors including A*, Bain Capital Ventures, Avra, Forerunner, Ribbit Capital, and Bond Ventures.

The startup offers text and voice-based customer support robots capable of automating chat, email, and call interactions, while providing software tools for enterprise customization.

Unlike conventional chatbots, Decagon's agent capabilities enable actions on behalf of customers across the entire support lifecycle. They employ complex business logic to reason, act as customer service representatives, analyze trends, and update knowledge base articles, improving performance through feedback from customer interactions.

The startup states its intelligent chatbots combine third-party large language models with proprietary fine-tuned AI algorithms. It explains that the system can blend and match various model types, even combining multiple models to find optimal configurations for different customer service tasks through continuous experimentation and testing to ensure helpful, friendly, and accurate outputs.

This fundraising follows Decagon's $65 million B-round just eight months ago, and a $35 million A-round exactly one year prior. This positions Decagon as one of the most well-funded AI-driven customer support startups, competing against tech giants like Salesforce and smaller firms such as Sierra Technologies led by former Salesforce co-CEO Bret Taylor.

Decagon's clients include Hertz, Duolingo, Eventbrite, and Chime Financial. CEO Jesse Zhang (shown left with co-founder Ashwin Sreenivas) shared in a blog post that Chime reduced contact center operational costs by over 60% while doubling its Net Promoter Score, a widely used customer satisfaction metric, using their AI agents.

Zhang revealed the company will use the funds to expand teams and sales to more enterprises. Decagon aims to build a future where every brand offers customers a "personalized AI agent" available 24/7 for comprehensive interactions and proactive actions on their behalf.

"This represents a new paradigm for consumer-brand interactions," Zhang stated. "We believe the future of customer experience is proactive, and more importantly, real, intelligent, and truly satisfying."
