Were engineers problem-solvers and builders who take the mission seriously but not ourselves. We automate the repeatable question the status quo and design systems that are as reliable as they are scalable. Whether were supporting space defense systems or healthcare advancements we build with the same principles: cloud-native solutions security by design and relentless simplicity.

Our name Blue (military shorthand for the good guys) and staq (as in software stack). Its who we are mission-aligned technologists building platforms that protect the worlds most valuable data.

Recognized Excellence Weve earned national recognition as one of Inc. Magazines Fastest-Growing Private Companies and consistently rank among Colorados Best Workplaces. But what were most proud of The systems we build the teams we develop and the mission outcomes we enable.
