How We Do It

We work as partners with our clients using an agile, sprint-by-sprint engagement model.

More about how we work



We want to ensure Fusionbox is a good fit for your project. Start with one 80-hour sprint and see real results. Get to know us as a partner without signing a long-term contract.



Fusionbox uses a Kanban board to record and visualize your entire project's progress. You always know the status of every task on the board: what's queued up, what's being worked on, and what's being tested.


You Decide What's Next

At the beginning of each sprint, you'll collaborate with our development teams directly to decide what's the highest priority.
