title: Haskell Offerings by Tweag
published: 2026-04-01
status: active
summary: Tweag brings its expertise in language design, build systems, and distributed systems to present several offerings as part of the Haskell Foundation's Ecosystem Partnership program.

I imagine a text like this posted in the Tweag website:

**Haskell offerings**

Tweag is now offering Development Partnerships leveraging their expertise in the Haskell language and its ecosystem.

Tweag is a company with a long tradition of engineering in functional
programming, with iconic projects like Linear Haskell, the GHC wasm backend,
rules\_haskell, ormolu, and inline-r, large contributions to the Cardano
ecosystem, and regular contributions to developer tools like Cabal, GHC, and
Liquid Haskell. In addition to Haskell-specific expertise, Tweag are
significant supporters of Nix and Bazel, technologies that bring functional
programming concepts to the realm of system management and software build
infrastructure.

**Offering 1** Because of its track record, Tweag is an ideal partner to
develop, test, and fine tune large scale build infrastructure and
cross-compilation, including projects that combine multiple programming
languages.

**Offering 2** Besides helping you build polyglot code bases, Tweag can also
help with language & tool integrations. Tweag has experience connecting
Haskell with R, Java, Scala, JavaScript, and SMT solvers.

**Offering 3** Tweag can help develop and maintain your Haskell infrastructure
for distributed systems. Tweag has been engaged for several years with design,
development, and testing of consensus and blockchain protocols for Cardano, and
earlier with Cloud Haskell.

**Offering 4** Tweag can help you design and integrate your changes in the GHC
compiler. Tweag has contributed language extensions like LinearTypes, QualifiedDo, and
StaticPointers. They regularly contribute performance fixes, develop the WASM
backend, and maintain GHC plugins as Liquid Haskell and inline-java.

Clients hiring Tweag through this partnership are also supporting the Haskell
Foundation and the Haskell ecosystem.
