Gigacatalyst

Gigacatalyst is a Y Combinator-backed company that turn every customer workflow into a native part of your SaaS with AI. Based in San Francisco, USA, the company participated in the Spring 2026 batch of Y Combinator.

We provide a white-label AI builder that learns your APIs and embeds in your product, so your customers can build their own apps on your SaaS. Each customer can now adapt your product to match their workflows perfectly and share it across their team with our in-built app store.

The result is that customers use your SaaS more, retain for longer, and expand quicker, because they get bespoke implementation for their exact usecase, without waiting.

Gigacatalyst was part of Y Combinator's Spring 2026 cohort, has a team of approximately 3 employees, and is actively operating.
