Kastro

For startups and indie hackers, customer support can become a full-time job before you even have a full-time team. Kastro is an AI-first customer support solution built for exactly this stage, using ChatGPT to create an AI support agent that handles repetitive questions, suggests relevant help center articles, and keeps your customers happy around the clock — without burning out your team.

Kastro brings AI and human support together in one streamlined workflow: the AI takes care of the common, repetitive queries so your team can focus on the complex issues that genuinely require a human touch. The result is faster response times, lower support costs, and a customer experience that scales with your growth — all from a platform designed with startups and indie hackers in mind.
