5(7 reviews)Scalable systems for complex business operations — delivered with clarity and predictability.
We help growing and established companies turn complex software initiatives into clear, scalable, and well‑managed systems. Our job is more than just software design and development — our job is taking care of your success. We don't jump straight into development. We start with discovery, solution design, and business analysis to define scope, architecture, integrations, and priorities before a single line of code is written. This is how we reduce delivery risk and protect your budget. We focus on three solution domains: 1. Custom Business Systems & Operational Platforms 2. Mobile Products for Customers and Operations 3. AI‑Enabled Business Workflows (AI under senior engineering control) Our strongest industry experience is in Food & Beverage, Real Estate, and FinTech — with growing expertise in iGaming, EdTech, and Travel Tech. Why companies choose us: clarity before development, structured delivery with PM and QA, domain‑aware solutions, and AI‑accelerated senior engineering. We work best with growing mid‑market companies, multi‑location businesses, and organisations that have outgrown spreadsheets or disconnected tools. We work as an extension of your business, in tight communication and total transparency — so there's no waste of time on back‑and‑forth. Start with a Solution Discovery call – to clarify scope, architecture, and the right path before any build commitment.31 works in Web ApplicationLocated in Tuckahoe, United States (+3)From €10,000 for Web ApplicationWorked in Education (+23)Speaks English, German(+2)51-200 membersDot Com Development

5(16 reviews)Build software people actually pay for.
Top awardedDesignli 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 MVP 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.8 works in Web ApplicationLocated in Greenville, United States (+2)Budget on requestWorked in Banking & Financials (+9)Speaks English51-200 membersProbey Services
