What Celest does

Celest is a backend-as-a-service for Flutter and Dart developers. It empowers Flutter developers with the tools and capabilities they need to become full-stack developers. We are introducing "Cloud Widgets", a set of primitives which enable you to declaratively define every piece of your backend and infrastructure in Dart. As the role of the front-end developer evolves towards full-stack proficiency, we recognize that existing tools have fallen short for those specializing in Flutter. Using the programming language and patterns Flutter developers already know from building their frontend, Celest enables developers to build and connect their apps to their backend with no additional tooling. We enable Flutter developers to concentrate on building features and delivering value to their customers rather than learning additional domains and fragmenting themselves across disparate toolchains.

What is your company going to make? Please describe your product and what it does or will do.

We are building Celest, a backend-as-a-service tailored for Flutter and Dart developers. It introduces Cloud Widgets, which let developers declaratively define backend logic and infrastructure directly in Dart, using familiar Flutter patterns. This removes the fragmentation Flutter developers face switching between frontend and backend tech stacks.

Where do you live now, and where would the company be based after YC?

I live in San Francisco, CA, and the company would remain based here after YC.

Explain your decision regarding location.

San Francisco is where I live and where our target developer community is active. It also offers proximity to potential investors and partners in developer tools and cloud infrastructure.
