Our Process

One Team, One Dream

We believe the best software comes out of close collaboration and partnership.

That’s why we literally integrate our team with yours. We encourage our clients and their developers to work out of our office so we can collaborate side-by-side. We don’t have contract lock-ins, so we succeed when you succeed. We write every line of code with an eye towards the future – ensuring that it’s easy to maintain and update.

We use an Agile process, which means we work closely with you in short, weekly sprints. We’ll be in constant communication, showing you new features as they are coded and getting your feedback. We test as we go and have developers working in pairs on every aspect of your code.

We’ll even help you grow your internal team with our technical evaluation services and team training. Because we’re in this with you for the long haul.

Here’s what to expect on your project:

Discovery & Kickoff

We take the first few days to collaboratively plan and develop a strategy. We set up the codebase and test frameworks, and jointly generate a backlog of work for the upcoming phases.


Rather than disappearing for months while you wonder what's happening, we work in one or two week sprints, with your close collaboration and approval at every stage.


Our UI / UX Designers visualize user stories by creating wireframes, mockups, and prototypes.


Our Engineers implement the user stories and designs by building fully functioning code and automated tests.


Our team presents you with a working product, ready for you to test and validate before we iterate again.

Deployment & Handoff

We deploy your new production code to live traffic. Our engineers seamlessly hand off the project to your team, providing all the necessary training to make sure they have the resources needed to succeed.

Delivering a Real-Time, Cloud-Based Web Platform That’s Transforming Recruiting

Thrive TRM, a Philadelphia-based startup focused on the hiring industry, needed a modern platform to power their new idea. The platform needed to handle real-time data seamlessly and work perfectly no matter what device their clients used. And because they are a growing startup, they needed it built in a way that would enable them to scale quickly.

Not only did PromptWorks deliver this platform on-time & on-budget, but they also shaved months off what the launch date would have been had Thrive TRM tried to hire internally for the project. By using PromptWorks, Thrive TRM immediately had a dedicated team of experienced developers who were able to build exactly what their startup needed. We even helped them hire their own internal developer team afterwards to continue development. Read More
