See your idea working in 7 days — before you commit to the build

For $1k, we build a working piece of your product — real code, deployed, that you own. Move forward and the $1k credits to your build. Works or it's free: miss what we agreed up front and we refund it. You keep the code either way.

HOW IT WORKS

Three Steps. Your Risk, Reversed.

The proof of concept is $1k, and every dollar credits toward your build. Miss what we agreed, and you get it back — code included.
01

Discovery Call

30 minutes to pin down the one feature that matters most — and agree, in writing, on what your proof of concept has to do. No pitch, no pressure.

Why Most Software Projects Fail Before They Start

"I've been quoted $50K+ just to get started"

We prove we can build it—for $1k, credited to your build. No $50K deposit. No months of discovery. A working proof of concept in 7 days, then a launch-ready MVP for a fraction of agency pricing. Miss what we agreed, and the $1k comes back.

"How do I know you can actually build what I need?"

You don't have to trust a pitch deck. We build a working feature of your product and hand it to you—real code, real functionality. That's your proof. And if it doesn't do what we agreed, it's on us, not you.

"I've been burned by developers who missed deadlines"

50+ apps shipped by ex-Meta engineers and PhDs. We set a 7-day deadline for your proof of concept and hit it—our reputation, and your refund, depend on it.

"I don't want to be locked into a vendor forever"

You own everything—code, servers, data—from the proof of concept onward. No licensing fees, no proprietary frameworks. Your team, or any developer, can pick it up and keep building.

See it work before you commit. That's the whole idea.

The Works-or-It's-Free Guarantee

We agree on what your proof of concept must do before we write a line of code. Hit it, and your $1k credits to your build. Miss it, and we refund every dollar—you keep the code either way. Here's what we'll never do:

Send you a slideshow and call it a proof of concept
Use no-code tools that break when you need to scale
Build something only we can maintain
Nickel-and-dime you with hidden fees after delivery
You own 100% of the code from day one. No licensing, no lock-in, no strings — and if the proof of concept misses the mark we agreed on, your $1k comes back.
