### 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

Java development firms build and implement customized Java applications for their clients. These developers work to understand each client’s specific business objectives and select the best developers from their company to meet customer needs. Java development services providers will continue to develop the tailor-made software until it is ready to be deployed. Companies with limited technology resources or those without an in-house development department utilize Java development firms to implement their customized Java applications. Java development companies will develop the product while helping clients understand and use the product. Developing Java applications is a process that requires using a number of different products.There are multiple [platforms as a service](https://www.g2.com/categories/cloud-platform-as-a-service-paas) (PaaS) that developers can choose to launch their application on, with some [free](https://learn.g2.com/free-paas) options. These free options will work best for smaller applications, and platforms will cost more when the applications scale.
