[Computing] Is Changing The World

We believe that great software will continue to reinvent every business.

Founded on Principles of Collaboration

General UI was founded in 2009 on the belief that our ability to use pervasive computing effectively will create profound opportunities for mankind to make positive change.

As the world becomes more automated, the knowledge work of software engineering and development will remain a great opportunity and challenge for human beings. The principles necessary to support the quality and productivity of this work are at the heart of General UI.

Our Values

Collaborative Teams

Our teams are supported from the bottom up, rather than dictated from the top down. We trust our teams' professionalism and coach ourselves to continually improve.

Lean, Data-Driven Design

We inform product decisions with data from real-world metrics, and we design lean products to create data to validate our clients' most important assumptions.

Test-Oriented Engineering

Continuous validation informs software architecture, which is designed to support continuous validation, in a virtuous cycle results in clean code, reliable software, and happy users.

Exposure and Transparency

By revealing depth gracefully, encouraging users and clients to engage in and understand our work, we build trust in our products and process.

Beyond Agile

More important than any given set of team practices, rituals, or tools is the team's shared trust and alignment in collaboration and continuous improvement.


Our trade is the sustainable and high-quality development of software products featuring clean code and user interface design that is nimble, deceptively simple and delightful.

Continuous Improvement

We coach everyone at General UI to invest in the perpetual improvement of our work and process, measured by the success of our customers and the satisfaction of their end users.

Supportive Management

We believe in and practice a supportive management model designed to maximize our professionals' discretion to use good judgment in providing excellent customer service.


Our company is only as good as the relationships it is made of. Serving these relationships by working for the well-being of our employees, customers, and end users is the purpose of General UI.
