## About

Curiosum is an Elixir-first software development company from Poland, built around a senior engineering team experienced in backend architecture, OTP-based systems, concurrency, fault tolerance, and long-term product development.

We work with startups, mid-sized product teams, and enterprise organizations that use Elixir to build, modernize, scale, or maintain reliable software products.

Since 2016, our Elixir experience has covered 50+ delivered projects across SaaS, healthcare, e-learning, marketplaces, real estate, gaming, and business-critical platforms.

Companies bring Curiosum into Elixir projects when they need senior technical ownership, stronger backend architecture, better performance, or support with complex product logic. We work with Elixir, OTP, Phoenix, LiveView, and PostgreSQL, with React, React Native, and UX/UI as supporting services when needed.

Beyond client work, we contribute through open-source tools such as Kanta and Permit, expert talks, technical resources, Elixir Hub, the Elixir Newsletter, the Elixir Survey, and Hologram sponsorship.

Clients usually work with us in one of two ways.

Team Extension Senior Elixir developers join your existing team to add technical capacity, close expertise gaps, and support ongoing delivery.

Project-Based DeliveryCuriosum takes ownership of a defined Elixir project, modernization, scaling initiative, or product build.

Elixir ConsultingSenior engineers review architecture, validate technical decisions, identify risks, and help plan the next stage of your Elixir product.
