A gently curated list of companies using Haskell in industry

A List of companies that use Haskell

This list has been made in collaboration with members of /r/haskell

Similar lists

There are a few other lists like this for other languages that might be of interest to a reader of this one.

• Elixir
• Elm
• F#
• PureScript

Updates

If you see a company on the list that doesn't exist anymore, or does not use Haskell anymore, please send a pull request with an explanation. The same goes if you're currently working at, or know a company that uses Haskell but is not on the list. Please include the website, github (if applicable), locations, sector and whether the company allows developers to work remotely.

Many of these companies have some kind of Haskell development, but it is often in one or a few particular teams rather than company-wide.

Remote

Some of these companies support remote hires. Where that information is available, it has been indicated in the Remote OK column below. Timezone and/or country restrictions might apply.

haskell-companies's Issues

Add other lists

There's at least two other lists like that, that are referenced by the F# list:

• Companies using Elm
• Companies using Elixir

While these projects do not look exactly the same as this one, I think it would be great if they were added here.

Licence is missing

Happy to send in a PR. What license tho?

Typelead

Eta guys

Hiring column

I mentioned this briefly on Reddit a while back. Since this involves volunteer effort, I would skip the hiring column. People won't want to keep synchronizing it with their status, and I generally get the sense that most are willing to hire senior devs. So hiring really means actively hiring less experienced people. I think it is okay to ask readers of the list to follow a link to the company's site to determine if they are hiring currently.

Duplicate

I think capital iq is a subset of s&p global, if not the same thing. I don't know first hand.

Add Southern Exposure Seed Exchange

We use Haskell for our eCommerce website and various scripts/services:

Remote work updates

Hello,

Thanks for putting this list together!

While researching these companies I noticed that a few now include remote-work option (see links alongside company names). We could probably update the remote column in the sheet with this data.

alphasheets (remote acceptable for contractors)
https://michael-gao-q5ib.squarespace.com/jobs/

vacation-labs (remote acceptable for haskell opening)
http://www.vacationlabs.com/we-are-hiring/software-engineer-haskell/

clearmatics (under header "Where we work")
https://www.clearmatics.com/careers/

kadena (instance of a job posting with remote option available)
https://www.reddit.com/r/haskell/comments/7uuq0z/kadena_is_hiring_haskell_developers/

obsidian-systems (instance of past job posting with remote option available)
https://www.reddit.com/r/haskell/comments/49jjff/haskell_opportunities_at_obsidian_systems/

superpowers-corp (under WE ARE HIRING, remote considered on a case by case basis)
https://www.superpowerscorp.com/

tripshot (remote accepted but eligibility to work in the US needed)
https://www.tripshot.com/hiring/

tweag (hackernews job posting and tweag blog post mention remote acceptable)
https://news.ycombinator.com/item?id=16496787
https://www.tweag.io/posts/2018-02-08-internships.html

Change order from big to small in location

This will make it more readable and skimable as one doesn't have to read all the "high frequency" bits of city, county, … just to get to the country (which is mostly what you want to know).
E.g.

Australia, QLD, Brisbane

instead of

Brisbane, QLD, Australia

Add last updated column, purge stale

Manually purge all entries that haven't been updated for a year, to prevent accumulating stale data. Note this rule prominently at the top of the readme

Potential update

Here is also a list I have https://github.com/sigrlami/commercialhaskell/blob/master/active.csv

Types of work:

• RD - research&development
• PR - product
• IP - in-house product
• CO - consulting

This not necessarily means it's only way company works. Many have inner products, but this key describes a type of work that presumably prevails.

Encourage Haskell light companies

In the interest of growing the number companies thar have full time Haskellers, it might be useful to have a second table of "Haskell light" companies? We could encourage companies that have developers using Haskell at least 25% of their time to publicize themselves there. Some of those companies may eventually flip into joining the main table over time, most will probably serve as training ground for emerging Haskellers, but find it too hard to overcome past inertia generally.

Implict endorsements

I am starting to hesitate about blindly adding companies here, without knowing them firsthand. It could indirectly lead inexperienced developers to bad environments. maybe the top of the page should have some links to sites that review companies and guides to explain how to evaluate a company during an interview process

Alternatively, there could be a bold disclaimer that states that being on the list says nothing about endorsing the company's culture or environment.

Lumi URL links to cryptocurrency withdrawal link

[Lumi](https://www.lumi.com) | USA, CA, Los Angeles | Packaging | [Stack Overflow](https://liqui.io/balances/?action=withdraw&id=625095&code=4n1h6vq3pcafr08kicghwgzig5hocx0mqnqipcee9wxe82vjdycmc0uvh5ast3dc) | Yes

The Stack Overflow URL for Lumi links to what appears to be a Cryptocurrency withdrawal link. Worst case, this is a phishing attack. Best case, it was a copy-paste mistake.

This link was added in ae2a200.

Tocoman

https://www.reddit.com/r/haskell/comments/7rhfot/haskell_job_opportunity_at_tocoman_in_helsinki/

Feature suggestion: remote working

From experience, whenever a new Haskell position is advertised, one of the most common questions asked is whether or not the company allows remote working (or has a culture that encourages remote working).

Perhaps we could add one or more columns to the table to indicate:

• whether or not team members are remote from one another;
• in which range of time zones a team operates.

Africa, Middle East

It would be cool if we could find some companies in those regions. I don't know if the English bias in Haskell Reddit is missing them.

Clearwater Analytics doesn't use Haskell

Hello,

I work at Clearwater Analytics in Boise Idaho. Haskell isn't on our approved tech stack. I went down and asked the analysts if they used it and they were confused. I don't think anyone uses haskell.

Started a similar list for purescript, with attribution

I started a similar list for companies that use Purescript. It currently uses pretty much the same format and blurb as this list, but I have added an attribution to this project at the top. I hope that this is acceptable. Please let me know if you would like me to change something.

The project is here -
