Let's talk about your specific needs and create a custom package.
Schedule a CallQuestions founders ask us (and our honest answers)
Because we believe founders should own their companies. Simple as that. We get paid for our work upfront, you keep 100% of your equity. If we're good at what we do (and we are), we don't need a piece of your company to make money.
All our packages include post-launch support (30-180 days depending on tier). After that, you own the code—hire anyone you want to maintain it. Or we can discuss ongoing maintenance if you prefer.
We recommend weekly 30-minute check-ins and quick async feedback on designs and features. The more involved you are, the better the end product. But we're built for busy founders—we handle the heavy lifting.
Absolutely. Your idea is your idea. We sign mutual NDAs before any detailed conversations. We've worked with stealth startups, public companies, and everything in between.
We eat the cost. Our proposals include detailed scopes and timelines. If we quote 4 weeks and it takes 6, that's on us. The only time timeline changes is if you request major scope changes mid-build.
We can't introduce you to VCs (we're not a fundraising platform), but we build products that impress investors. Clean code, great UX, scalable architecture—the stuff that matters in due diligence.
That's literally our specialty. We translate your vision into technical requirements and build it. You don't need to know React from Python—that's our job. You focus on the business, we handle the tech.
Even better. They can focus on architecture and long-term decisions while we handle the execution. We work great with existing tech teams who need to move faster.
Stop burning runway on in-house development. Launch your startup in 30 days.
