We’re a small software company. We make apps and tools for specific jobs.
Here’s what we’re working on right now, and everything else we’ve made.

Maid League

How we decide what to build
- 01
We ask first
Before we build something, we put up a page describing it and see if people sign up. That’s where Maid League is now.
- 02
Then we build it properly
If enough people want it, it gets our full attention. We work on one product at a time.
- 03
We don’t disappear on you
If we ever stop running something, the people using it will hear it from us first, with time to move.
