Decagon

Decagon transforms your customer support from a cost center into a growth engine using generative AI agents that do more than just answer questions. You can deploy AI agents that actually perform tasks, such as processing refunds, troubleshooting technical issues, and updating subscriptions by connecting directly to your internal tools and databases. This ensures your customers receive immediate, accurate resolutions without waiting for a human agent to intervene.

The platform is designed for mid-market and enterprise companies that handle high ticket volumes and require more than basic chatbots. You can maintain full control over your brand voice and data security while significantly reducing your support costs. By automating the repetitive aspects of support, you allow your human team to focus on high-value customer interactions that require a personal touch.
