Someone will have to explain the value proposition to me...

We have git.

jujutsu works with git.

git can do everything jujutsu can do (otherwise, jujutsu couldn't work with git).

Thus, jujutsu is a UX / new steering wheel.

ERSC is trying to be a GitHub competitor with what surplus value?

Don't get me wrong, GitHub has a slew of its own problems, but I have not seen any commentary on how ERSC addresses any of the downfalls GitHub has too. We're jumping from one frying pan into another, currently-cooler one?

What about SourceHut? Codeberg? They could offer the same steering wheels.

Edit: Thank you to everyone who replied. The enterprise/teams infrastructure angle makes sense.

Working with Martin has been a real pleasure, and we'll have some more stuff to talk about very soon!

excited for what you guys would be coming up with ;) btw, did Martin leave google?

Thanks!

Martin left Google for this, yes.

what a lovely website

Thank you! We liked our old look, but one funny thing about how things are going in the world: our old color scheme was too close to what happens when you ask Claude to generate a site, and so even though we paid a human to build it, we didn't want to communicate slop, especially because that's not what we did! Nick Noble is our designer, he put in a bunch of work on this, and I really like it too.

I love how little latency there is on your website. I'm often thrown off by websites freezing on navigation, something we euphemistically call "loading". I feel we should have moved beyond that in the year of 2026. Your website really respects the user in this regard. Aesthetics are splendid as well.

I might be mistaken, but I always figured the end goal for jujitsu was to use its own backend. Supporting git-colocation seems like a compatibility case to bring users over.

If I had to guess, then I would say ERSC is trying to build a `jj` forge based on this new hire and that would be amazing imo.

We'll be saying more about this very soon, but the short version is this: we are not building a GitHub competitor in the way that SourceHut or Codeberg are. We are building infrastructure for enterprises, not a social coding site.

While jj works with git, it doesn't have to. jj has the ability to work with many backends. Git is the popular one in the open source world, but that doesn't mean that other ones are not possible. And that's the core tech we have built.

With the rise of agents, more and more companies are running into the limits of what Git can do. It was never designed for large monorepos, and so there are performance issues, but also features that it's missing, that are important once you start trying to scale things up to an entire organization. Companies like Meta and Google ran into these things well before the present moment, but you don't have to be a FAANG these days to be running into this sort of stuff.

We also understand that incremental adoption is really important, especially for something as fundamental as source control. So our tech also has a git ingress/egress that will work with the core functionality, but more advanced things that git simply can't do will end up requiring using a non-git protocol. jj is the bridge between those two worlds.

I hope that makes sense! We have been in psudeo-stealth for a while now, this is the start of us coming out of our shell a bit and actually talking about what we're doing.

this is a very legit question. my few cents:

I don't know how experienced you are with jj, but one thing I can say for sure is jj offers significant ux improvements over git and they plan to have a backend eventually. we might see the first implementation from ersc. and from their website I see they are already taking things like agents into account from day one. so we might be in the verge of getting something that scales better with modern day workload?
