We definitely understand the need for serious design. That's exactly why we've raised funding. Currently we have open roles for designer, content design, UX lead, UX researcher, etc. Please let us know if you have any referrals for design candidates.

Hiring arbitrarily is kind of weird. Having a UI team for the sake of it could be considered quite harmful because those designers can't ever be idle.

And in any event, a software such as gitlab doesn't need to be pretty, it needs to be usable, fast and bug-free.

Our dribbble is relatively sparse at the moment, but we do have it: https://dribbble.com/gitlab

We have quite a good UI/UX team in my opinion, but there's a lot of surface area to cover. If there's anything specific you think could be improved upon feel free to open an issue. :)

If anything the bottleneck right now is with frontend developers being able to implement features/design improvements, not with designers.
