We started because good engineers were being wasted on bad processes
Seven years later, we're still fixing that — for mid-market companies that need senior execution without the Fortune 500 price tag.
Where we came from, and why it matters
Xellagain was founded in 2017 after our predecessor firm, Xelleration, was successfully acquired by Speridian. Rather than disperse, the core team made a decision: build something leaner, more focused, and more honest about what good technical work requires. No filler staff. No overpromised timelines. Just senior engineers who care about the outcome.
We don’t simply "staff" empty seats—we engineer environments, lead cloud migrations on Microsoft and AWS, and build secure architectures that differentiate your business.
Our Mission
"To provide high-value, deeply specialized technical resources to clients who prioritize uncompromising quality, supreme performance, and operational speed."
Our Core Values
The principles that define our engineering philosophy and client engagements.
No Shortcuts
We don't ship a quick MVP and call it done. Security reviews, code quality, architecture decisions — we think about the second and third-order consequences before we write the first line.
Move Fast, Think First
We operate with the compliance discipline of an enterprise firm and the sprint velocity of a small team. You shouldn't have to choose between rigor and speed — we've built a model that doesn't require that tradeoff.
Senior Engineers, Not Pyramids
Most firms build work pyramids: one senior architect on top, juniors doing the actual coding below. We don't. The engineer you meet in the scoping call is the one writing the architecture and reviewing the final commit.
Why our cost structure is impossible to match onshore
U.S. leadership and accountability. Engineering execution running 24 hours. You get both at a price point that onshore-only shops simply cannot offer.
Irvine, USA (HQ)
Our strategy, technical architecture, and client relationships are managed from our California headquarters. Business-hours calls, U.S.-based contracts, and direct access to the people making decisions.
Asia Engineering Center
Senior engineers and security analysts keep projects moving overnight. When your team logs off, ours are mid-sprint. No knowledge loss, no waiting 8 hours for a PR review.
