We make software
people keep using.
Lumen Labs Limited is a small software studio in London, United Kingdom. We do not take client work — we make a short list of our own products and keep them running, for as long as people use them.
What we're building
Two divisions.
Everything here is ours. Red Vector Games is our games imprint; Doubles is our training system. Both are built, run and supported by the same small team.
Red Vector Games
GamesOur games imprint. Two titles: Crosslane, a three-lane runner told across six chapters, and SIXTY, a sixty-second daily puzzle. No adverts, no third-party trackers, and an account only if you want your progress to follow you.
The studioDoubles
WaitlistA training system for people who lift and run. Most marathon plans treat lifting as the thing you drop when the mileage climbs. Doubles builds the running around the lifting instead, reads every set and every mile, and adjusts the plan so neither one wrecks the other.
MoreHow we work
Fewer things,
kept running.
We own what we ship
There is no client work here, so nothing gets abandoned the day a contract ends. Every product on this page is ours to maintain, and the plan is to maintain it.
Small on purpose
A small company can only build a few things at a time. We would rather that be the constraint than pretend otherwise — it is why the list above is short and why everything on it is finished before it is announced.
We answer email
Support for anything we make goes to a person, not a ticket queue. support@lumenlabshq.com reaches us, and so does hello@lumenlabshq.com for anything else.
