Python Web Development

Fusionbox is exclusively a Python web development company. Founded in 2002, we’ve completed 100s of Python and Django web development projects over the past 17 years. Our Denver-based team of senior engineers has a passion for complex projects and a commitment to security.


Custom Python Development
We have 18 years of experience with Python software development, data architecture, and UI/UX design. We can take over an existing project or start new ones.

Staff Augmentation
Add one of our experienced software engineers to your team and see how a fresh set of eyes can spark increased productivity from your engineering staff.

Project Rescue
Have you lost your current developer or need to add resources to your team? Fusionbox can quickly pick up where they left off or add to your existing team.

Code Review & Training
Allow our senior engineers to review your code for security audit or software design decisions. Speak with us to provide Python or Django training to your internal developers.

We have experience with complex hosting environments on AWS, Heroku, and Linode. We can do anything from a simple audit to assuming full management for you.


100% US-Based
Our team is entirely located in the U.S., with headquarters in Denver, CO. We do not outsource to any other teams, ever.

Python Only
Fusionbox's engineers only work in Python. That means, you are getting expert engineers who are highly skilled in Python and have a passion for it.

Senior Engineers
All of our engineers have senior-level experience and extensive knowledge of security concerns, architecture, and DevOps.

Sprint-by-Sprint Engagement
Purchase one sprint to make sure we are the right fit. No long term commitments, minimums, or retainers.

Fast Onboarding
Fast onboarding means you have direct access to software engineers who will be writing code in days, not weeks or months.

Fully Agile
Our Agile process is incredibly mature and ensures transparency. You will know exactly who is working on what and when.

Retul Custom Bike Fitters


Custom Bike Fitting Software

Retul's proprietary bike-fitting machines needed a web-based bike configurator. The bike fitting machines send data to the web application (Frame Finder), which uses the data to draw the ideal bike for the rider. Frame Finder then allows the rider to visualize varying sizes of frames and adjustability ranges of parts to select the best combination for optimal fit.

Fusionbox has worked with Retul over several phases. The newest version allows cyclists to virtually "try on" over 200 bike models and 1,000s of components and then shop for the chosen bike parts through an e-commerce system.

We Love Django

Fusionbox has been using Django exclusively since 2013. Django is scalable, secure, and as a batteries-included framework, Django offers lightening fast concept-to-software speed. And because it's written in Python, it's a joy to use.
