Why Most Software Projects Fail Before They Start

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

We prove we can build it—for free. No $50K deposit. No months of discovery. A working prototype in 3 days, then a launch-ready MVP for a fraction of agency pricing.

"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.

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

50+ apps shipped by ex-Meta engineers and PhDs. We set a 3-day deadline for your prototype and hit it—because our reputation depends on it.

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

You own everything—code, servers, data. No licensing fees, no proprietary frameworks. Your team (or any developer) can pick it up and keep building.

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

What We Won't Do

Our prototype guarantee means something

Send you a slideshow and call it a prototype

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. No licensing, no lock-in, no strings.

"His exceptional ability to lead development teams and direct technological innovation projects has transformed our platform."
