About Us

Technology Driven Software Company

Milecrew - Roland Guelle und Felix Hassert

Simple and good software is not a matter of course. Endless technical possibilities, new frameworks every day and a shortage of skilled staff let you stray from the roadmap and no longer deliver results in milestones. Instead, the team gets lost in tooling and processes.

We are the experienced Crew for your software project. We help you to ensure that the digitization of projects and products does not end up on strategy slides or in backlogs, but in functioning software for the users.

Creating benefits with software

Functioning software with fast benefits and short innovation cycles is our passion. Living agility instead of celebrating it.
We offer our experience in the entire lifecycle of software product development as services:



Doing the right things. With today's unlimited possibilities, that's one of the biggest challenges:

  • CTO as a Service + Team Crew
  • Status quo analysis, architecture review and roadmap conception
  • Individual solution finding with use of standard technologies


Product development is not just coding. It is a holistic concept and passion:

  • Development of technology and product concepts
  • Realization and implementation
  • Project management and responsibility


The crucial phase of your product is the operation, where it brings the features to its users and generates feedback:

  • Iterations with the product as further development
  • Monitoring and optimization
  • Rollout and operation
