### Designli

Designli helps non-technical founders turn software into real, revenue-generating businesses.  Most agencies hand over code and walk away, leaving you to build the business yourself. We work differently, measuring our success by your traction - real users on a live product and real signs that the business is growing.  Every engagement is built around a guaranteed outcome:  For founders starting from scratch, our TractionLab program puts a real user on a working Version 1 within 30 days, or your next month is free. From there, the whole team works to turn that first user into many, and early usage into real revenue. For founders who already have something live, we start with a free one-week Impact Week that pinpoints exactly what's holding your product back. You walk away with a customized plan and a guaranteed Day-30 outcome that clears those roadblocks, so you can get back to chasing traction and your vision instead of fighting your product.   The burden is on us to prove we're the right partner. Picking a software development agency is one of the most important decisions you'll make as a founder, and we don't think that risk should fall entirely on you. That's why your first 14 days are fully refundable, and you can cancel any time with 30 days' notice. We work using Hypothesis-Driven Development. Building software is cheaper than ever with AI-empowered engineers; the hard part is knowing what to build and whether it worked. So every change we make carries a business metric and a clear bet about what it should move, and we measure whether it actually did. The result is a real feedback loop on whether your product is getting better each week and driving more usage and revenue. Each engagement is staffed with a small, senior pod that gives your product full-time focus and founder-level care, and is paid on outcomes, not promises. Learn more at https://designli.co
