It's Bright in Here
Overview
Fusionbox is a software development agency in Denver, Colorado. We've helped companies develop secure, well-architected software since 2001. Our work results in a direct and measurable impact on your business.
We are a small team of talented Python Engineers and UX designers. To say Fusionbox is a builder of software is certainly true. But it’s a small part of the story. Within our code is a unique approach to business:
- Hire people obsessed with problem-solving.
- Be human to tune in to our clients’ problems.
- Use technology as a means to solve problems.
- Be the best at that. We've helped organizations large and small not only writing code, but developing their vision for how to get there.
Our clients include the Colorado Lottery, FirstBank, Delta Dental, Boston Mutual Insurance and Citywide Banks. We'd love to talk about your project.

“Trusted partner for custom software development.”
One of the greatest benefits of working with the team at Fusionbox is their expert attention to understanding both our immediate objectives as well as our overall vision. This collaborative approach has resulted in quick solutions to our immediate problems with an eye toward our future needs. Since Fusionbox has thoughtfully built the foundation for our custom platform, our new functionality requests are met with simple iterations rather than costly redesigns. We think of Fusionbox as a trusted partner in our efforts to deliver a premium experience to our clients.
“CEO, Emotional ABCs, Inc.”
I am the CEO of Emotional ABCs, Inc. We have been working with Fusionbox for a few years now and we have been extremely impressed with them throughout this time. Our overall experience using their services has been just fantastic. We have found that they care about our program and our program's success as much as we do. Molly Baron who runs the day to day interactions between the developers and the companies like ours has been fantastic. It sounds like a cliche but I literally don't know how she keeps all these balls in the air. Their service quality and reliability has been and is excellent. Everything is not always so clear cut in the software world since so much is constantly changing but we really feel that Fusionbox has our best interests at heart, even when they're suggesting that we not follow a certain path that we might have thought would be a good choice. Their reliability and technical ability is great. And, even more, they seem to care about the quality of their work and we think this comes from the company owners who care about their employees work/life balance and engagement at work. Definitely 5 stars.
“Great team! Amazing product!”
It was a complete pleasure to work with FusionBox. They were very attentive to the business needs and were able to effectively provide a great product. I've worked with FusionBox on numerous occasions at various companies - each time they delivered a fantastic product. I highly recommend working with FusionBox on any web or software development product.
“Web Development Company”
I work for Craters & Freighters and have done two whole new websites with Fusionbox. Not only were they reliable, but they were on task and completed a lot of complex code in a timely manner. Over the years, I've had customers compliment our website design. Very friendly and knowledgeable staff as well.
“Fusionbox gets it”
We recently contracted with Fusionbox to create an advanced calendar experience within our Salesforce portal used by our dealer network. They did a great job in listening to our requirements and translating them into a functional and well thought-out design that our dealers love.
