A one-person studio building one app at a time.
We price things fairly, publish what they cost to run, and plan to still be here in ten years. That's it. 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 — no ads, no investors, no selling data.
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.
Everyone gets the whole app
Every feature ships to everyone — the full product is the only product. The price just keeps it running.
Our first product
Denly — co-parenting made simple.
A private, shared workspace for two co-parents — schedule, money, documents, and messages in one calm place. One price covers your whole Den: $29.99/year, with a 14-day free trial. And no one is turned away.
Launching Summer 2026 · iOS & Android
- Shared calendar for two homes
- Costs, settled clearly
- A secure document vault
- A permanent, timestamped message record
From the founder
Why I'm building this
I'm Dan, a software engineer. I started GuildStack Labs because I think small, honestly run software is still worth building — and worth paying for directly, instead of with your data.
Subscriptions pay the bills and the costs are public. The first product is Denly, a co-parenting app — built for a problem I grew up with.
