At Stack Builders, we specialize in high-assurance software built with functional programming. With over 3 million lines of Haskell code in production and deep experience across industries like finance and cybersecurity, we deliver reliable, scalable systems where performance and correctness matter most.

Our engineers are active contributors to the FP community, presenting at top conferences and building open-source tools. We work closely with your team through a transparent, collaborative process—ensuring clear communication, flexibility, and results from start to finish.

Advantages of Functional Programming

Functional programming brings a disciplined, mathematical approach to software development. It’s ideal for high-assurance systems and fast-moving tech environments.

Reliability Through Pure Functions Predictable behavior reduces bugs and makes systems easier to test, maintain, and evolve over time.

Immutability = Fewer Side Effects Immutable data simplifies reasoning about state and makes concurrency safer and more scalable.

Strong Typing for Safer Code Catch issues early for powerful type systems that prevent whole classes of bugs at compile time.

Scalability by Design Stateless architecture and composable functions allow systems to scale with confidence and precision.

Easier Refactoring and Reuse Modular, pure functions support reusable code and simpler refactoring that accelerate development.

Haskell Haskell’s pure functional model, strong type system, and emphasis on immutability make it ideal for building complex, safety-critical systems that stand the test of time.

Scala Scala combines the power of functional programming with the flexibility of object-oriented design, making it perfect for performance-sensitive environments.

Elixir Elixir brings functional programming to distributed systems. Built on the Erlang VM, it powers real-time apps with high reliability and fault tolerance.

Nix Nix applies functional programming to system configuration and deployment, ensuring reproducible, isolated, and predictable builds.
