We help organizations improve how they design, develop and deliver software.
Domain modeling is a powerful tool for clarifying and refining our understanding of a subject area, and for identifying opportunities for optimization and improvement. By carefully considering the needs of stakeholders and the nature of the domain, it is possible to create effective and useful models that can facilitate communication and drive progress.
FModel is a set of libraries that aims to bring functional, algebraic, and reactive domain modeling to Kotlin / TypeScript / Rust / Java. It is inspired by DDD, EventSourcing, and Functional programming communities.

A Postgres powered event store for efficiently prototyping event-sourcing and event-streaming with a minimal footprint.
It is a platform for efficiently prototyping and implementing event-sourcing and event-streaming without the need for additional infrastructural components. All schemas, constraints, and SQL functions are implemented in the database/close to the data. No additional tools, frameworks, or programming languages are used at this level.
We run it on Supabase, but you can choose to run it anywhere, with almost all cloud providers, managed or not.
