Independent software, built to last.
We build one product at a time, publish what it costs to run, and hold a reserve so it's still here next year. That's the strategy.
What we build
A few things, done well
We'd rather do a few things well than everything at once. Each product stays small enough to maintain properly, and subscriptions are the only thing funding it.
You can check the math
We publish what our software costs to run and where every subscription dollar goes. You don't have to take our word for anything.
We don't want your data
We collect what the app needs to work, and nothing more. It isn't sold, shared, or mined for ads.
Built to outlast a bad year
We hold an operating reserve, you can export everything you put in at any time, and there is no investor to sell you to. Every feature ships to everyone — the full product is the only product.

From the founder
Why I'm building this
I'm Dan, a software engineer, and the person who answers for GuildStack Labs — there's a name on the door. I started it because I think small software is still worth building, and worth paying for directly instead of with your data.
Subscriptions pay the bills, the costs are public, and a reserve covers the lean stretches. The first product is Denly, a co-parenting app — built for a problem I grew up with.
