About Bluestaq
At Bluestaq, we build secure data platforms that matter for space missions, national defense, healthcare systems, and commercial innovation. Founded in 2018, we've become a leader in enterprise software and secure data management by staying focused on what counts: modern architecture, operational excellence, and mission impact.
We're 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 we're 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). It's who we are, mission-aligned technologists building platforms that protect the world's most valuable data.
Recognized Excellence We've earned national recognition as one of Inc. Magazine's Fastest-Growing Private Companies and consistently rank among Colorado's Best Workplaces. But what we're most proud of? The systems we build, the teams we develop, and the mission outcomes we enable.
