Spin the bottle, but make it mission-ready. 😂🚀When the options are Big Corp, Flashy Promises, Speed-Over-Fit, and a team that actually cares—we’ll choose the long game every time.
Big Corp has binders. Flashy Promises has glitter. Speed-Over-Fit has shortcuts. We have years of choosing the right people for the mission—and showing up for them, long after day one.
If you value accountability, trust, and the big picture, you’ll see why the bottle stops on us!
We heard that 2026 is the new 2016!? In 2016, and prior, we set a simple standard: do excellent work with excellent people.
Today, in 2026, the standard stands—substance over flashiness, quality over quantity, and team over the individual. We hold each other accountable. We reward the teammates who earn it. And we remember that integrity is the foundation whether you’re hiring for a critical program or collaborating inside the company. Back in 2016 we weren’t chasing volume—we were building a team.
In recruiting—especially in GovCon—it’s tempting to fill a seat fast. We slow down to get it right. We look at the whole person, the mission, and the program fit. That’s how you protect culture, deliver consistently, and keep customers and teammates winning for the long haul.
To everyone who’s been with us since 2016 (and long before): thank you for setting the standard. To everyone who joined along the way: thank you for raising it. Here’s to the next decade of doing it the right way—with integrity above all else.

Did you know it’s National Wikipedia Day!? We aren’t quite hype enough to have a Wiki page yet, but we dreamed up what ours might say if we did have one! What do you think? 🤗🤗✅✅
In actuality, Wikipedia pages aren’t just handed out like free chips at a Mexican restaurant! 😂 To qualify, you need:
⭐Notability: Significant coverage in reliable, independent sources (think news articles, not just your own blog).
⭐Verifiability: Facts backed by published sources anyone can check.
⭐Neutral tone: No marketing fluff—Wikipedia wants encyclopedic, not salesy.
⭐Reliable references: Multiple third-party sources, not just your website.
We’ve got the mission, the memes, and the milestones—but fame? Working on it. Maybe if we keep growing, we’ll earn that coveted spot one day. Until then, enjoy our “future page” and celebrate #WikipediaDay with us!

450 in‑houses last year.
At Cornerstone Defense, “in‑houses” are face‑to‑face meetups where our recruiters get to know candidates before their formal interviews—so every conversation starts informed and personal. We ran 450 of these last year, and the results show in our hiring quality and retention.
