Our Process for Software Development

Our holistic method for designing, building, and launching market-leading custom software solutions.
Step one
‍Unpack the Challenge
Before we even start, we set goals, and we align your stakeholders.
We help you zero in on the most impactful ideas, allowing you to solidify the vision for your product.
Assemble the Squad
Align on collaboration, governance, mission, introductions, and trust-building.
A squad is a flexible, resourced team working towards technology and business objectives.
Step Two
Develop a
Product Hypothesis
Through ongoing discovery, design, and prototyping, we leave no stone unturned.
We map the features on your roadmap to user needs through research.
Step Three
Iterative Design
& Build
Discover continuously throughout the project.
For a product to be successful, it needs you to continually validate and evolve it through high-fidelity experiments that get tested before code.
Step Four
Wide Scale Launch
Marketing, training, and iterative
product enhancement for a successful launch.
Throughout the process, we gather feedback by putting your product in the hands of real users. Test-driving your vision is critical before further investment.
Step Five
Enablement and Transition
We ensure that you get the maximum value from your innovation investment.
The success of your new, market-leading product entirely belongs to you. We ensure a smooth handoff to your internal team — in addition to providing ongoing support services.
