Rust, Haskell, and the Architecture Behind Solana: Interview with Greg Fitzgerald
In this interview, we speak with Solana cofounder Greg Fitzgerald about why Rust ultimately proved to be the right fit. We discuss how his background in C++, LLVM, and Haskell shaped Solana’s architecture, what functional programming contributed to the design of a high-performance blockchain runtime, and why Rust’s combination of strong types, memory safety, and low-level control worked particularly well for BPF and virtual-machine development.

From Scientific Computing to Type-Safe Finance: Bitnomial
In this interview, we discuss what needs to change for Haskell to reach more developers and companies, and where the Haskell Foundation can have the greatest impact. We also look at Haskell from the perspective of a large financial system at Bitnomial: how type safety and effect tracking help engineers manage correctness at scale, where the complexity budget for advanced types should be spent, and why technologies such as Servant remain powerful tools for moving guarantees from individual applications to entire systems.
Daml for Haskellers: interview with Heitor Toledo Lassarote de Paula
In this interview with our Daml Team Lead, Heitor, we examine which Haskell intuitions transfer successfully to Daml, where analogies such as Update and IO break down, and how developers should reason about authorization, visibility, contract lifecycles, and testing. We also discuss learning paths and tooling for Daml developers, common mistakes made by Solidity programmers, and the practical topics covered in the upcoming Daml Smart Contracts Development Guide.

Haskell, Strong Types, and the Next Generation of Bioinformatics: interview with Michal Gajda
Bioinformatics combines scientific discovery with the challenge of processing large, complex, and imperfect datasets. In this interview with Michal Gajda, we explore how Haskell’s strong types, purity, and functional abstractions can support reliable and high performance biological data processing.
Drawing on projects such as hPDB, JSON Autotype, and XML TypeLift, Michal discusses scalability, parser development, and the barriers to wider adoption of functional programming in bioinformatics. He also considers how better education, tooling, and AI assisted programming could make Haskell more accessible to future scientists.

Rust, C++, and the Tradeoffs Behind Safe Low-Level Code: interview with Nikita Lisitsa
In this post, we interview Nikita Lisitsa about C++, Rust, systems programming, and game development.
We discuss whether C++ is still the default path into systems programming, where Rust fits in, and how both languages may coexist over the next decade. Nikita also shares his perspective on memory safety, language complexity, game engine design, real-time physics simulations, renderer abstractions, and the lessons he learned from shipping Costa Verde.

Haskell in Mercury: Interview with Max Tagher
In our Functional Futures podcast episodes, we interview technical leaders from companies that use Haskell for real-world tasks. This season will be dedicated to the business side of development with functional programming.
Our guest is Max Tagher, the co-founder and CTO of Mercury, the fintech startups use for banking* and all their financial workflows. Mercury has been using Haskell from the start of the company, from scratch. And our conversation will be dedicated to that.

Haskell in Production: Textcontent
In our Haskell in Production series, we interview developers and technical leaders from companies that use Haskell for real-world tasks. We cover benefits, downsides, common pitfalls, and tips for building useful Haskell products. Today's guest is Marc Scholten, the Founder and CEO of digitally induced. In this interview, we discuss their product, textcontent.ai. It is a text-generating tool that helps marketers create a distinct style and tone of voice. Marc explained how it differs from other options on the market and how they use Haskell in their product.
Rust in Production: FOSSA
In this interview from our Rust in Production series, we speak with Jessica Black, a senior software engineer at FOSSA, a developer-native open source management platform. Jessica has been working at FOSSA for over four years and has been on the Analysis team for the past two years. The Analysis team manages FOSSA CLI and FOSSA Broker, along with services that power more advanced capabilities like snippet scanning and vendored code matching.
Haskell in Production: Chordify
In this edition of our “Haskell in Production” series, we interview Jeroen Bransen from Chordify, an online platform, which turns any music or song into chords. Jeroen has been working at Chordify since 2016. We discussed how Chordify ensures the correctness of Haskell code and scalability of its codebase, which libraries they use in their work, and more.
Haskell in Production: FOSSA
In this edition of our "Haskell in Production" series, we feature FOSSA – a tool for open-source risk management. Our guest, Eliza Zhang from the engineering team at FOSSA, discusses her experience using Haskell in backend analysis services and CLI. Read further to learn about the benefits and downsides of Haskell he encountered while working on the project, as well as tips he would give to teams starting Haskell projects like his.
