Development Services

Build safe and secure applications with one of the leading Haskell development companies.

Since the compiler detects large classes of issues at compile time, Haskell code is much more reliable than code in languages like JavaScript or Python. This leads to lower development costs and happier users.
Due to the well-optimized compiler and good support for concurrency, your application will be fast, reliable, and performant. Therefore, the Haskell programming language is a perfect choice for fintech apps or blockchain projects.
Because of the strong focus on types, Haskell code is easy to maintain and improve. This means that it is much easier and cheaper to support your application and add new features to it.

Haskell is the tool you need to build better software

Haskell is a general-purpose functional programming language that is mainly used for backend development.

With Haskell, you can create software that is efficient, reliable, and easily maintainable. It is used in fields where correctness is mandatory, such as fintech, blockchain, biotech, healthcare, and others.

Why we’re your best choice for a Haskell team

Since Haskell is the main tool we use at Serokell, we know it inside out. Our developers have learned the tips and tricks for writing Haskell code that is performant and industrial-grade, and we are ready to build any kind of software with it.


Serokell has worked primarily with Haskell solutions for 5+ years, and we know what is necessary to launch a successful product with Haskell quickly and painlessly.


We have a dedicated team that works on GHC, the most widespread Haskell compiler, and moves the programming language forward.


Our engineers teach Haskell and functional programming at universities, mentoring new Haskell developers that become industry experts.

Full-stack capabilities

Our expertise covers every part of software development. Frontend or backend development, DevOps, or QA, we have people that can help you achieve your goals.
We built the settlement layer of Cardano, one of the largest and most innovative Proof of Stake blockchain platforms, and helped support its federated launch and token distribution.
We contributed to Tezos, one of the top open-source blockchain platforms. Our contributions include two smart contract languages made with Haskell, a set of developer and testing tools, packaging solutions, and multiple smart contracts.
Telegram blockchain contest
Our team was awarded first prize in the smart contract competition launched by TON (Telegram Open Network) for our async payment channel and multisignature wallet, which was written in a domain-specific language built with Haskell.
