What Fusionbox does

Fusionbox is a Denver, Colorado-based custom software development consultancy founded in 2002, operating with a small (11-50 employees), entirely US-based team of senior engineers and no offshore outsourcing. The firm specializes exclusively in Python and Django application development since adopting Django as its sole primary web framework in 2013, supplemented by React/React Native front-end and mobile work, UX/UI design, certified PostgreSQL database consulting, and application security services including ethical hacking, penetration testing, and HIPAA/PCI compliance consulting. Several internally authored open-source libraries (Widgy CMS, Memorist decision tracker, AuthTools, Dinero payment library, Mouseware password generator, and Eek spider) have been adopted into the Django ecosystem or the Django core itself, and the firm maintains a continuous community presence through PyCon and DjangoCon sponsorships.

The business model is hourly professional services delivered through a sprint-by-sprint engagement model: an introductory 80-hour sprint is offered with no minimum monthly commitment, no long-term contracts, and no expiration on purchased hours. Published rates are $175/hour for ongoing long-term engagements and $195/hour for one-off projects, with staff augmentation also available. Go-to-market is sales-led and direct, supplemented by content marketing (technical blog, Fusionbox University educational series, case studies), community engagement (open-source contributions, conference sponsorships), and Clutch-driven referrals. The client base spans government (Colorado Lottery as agency of record), financial services (FirstBank, Citywide Banks), insurance (Delta Dental, Boston Mutual), education (Stanford, Emotional ABCs), manufacturing (Cummins, Gallery Carts), telecommunications (Comcast), and nonprofits (Habitat for Humanity, Boys and Girls Clubs, Outward Bound).

Fusionbox is privately held with no disclosed institutional funding, parent company, or subsidiaries; ownership appears founder/management-held under CEO Ivy Hastings and President Alexander Groth. Revenue is not publicly disclosed. Notable long-tenure client outcomes include sustained support of the Colorado Lottery's digital properties (handling over $4.3B in cumulative state contributions) and a multi-year design-and-development partnership with Emotional ABCs, which now reaches 200,000+ educators across 120 countries.

Revenue model

1. Professional Services / Consulting: Fusionbox charges hourly for custom Python/Django development, UX/UI design, DevOps, PostgreSQL consulting, and application security services. Rates range from $175–$195/hour depending on project type (long-term projects at the lower rate, one-off projects at the higher rate). Revenue is generated through sprint-based engagements (80-hour sprints) with no minimum monthly commitment. Hours do not expire.
2. Open Source Tools (Free): Several open source libraries (Widgy, Memorist, AuthTools, Dinero, Mouseware, Eek) are freely available. These tools generate no direct revenue but serve as marketing/differentiation assets demonstrating technical expertise.
