Not just so they can shine during their internship 🌟 — but so they walk away with knowledge that helps shape where their career paths go next. 🧭✨
 
We had great conversations, lots of learning moments, and plenty of laughs along the way. Nothing makes us happier than watching our interns grow, ask big questions, and build confidence in the fields they’re exploring. 🙌💡

✨ Another amazing day partnering with Boulder Crest! 🌿💪
Our team spent yesterday mulching (and mulching… and mulching!) to help get the property ready for their big Red, White & Bluegrass celebration happening this weekend! 🎶🌭🥤

Supporting Boulder Crest Foundation’s mission to serve combat veterans, first responders, and their families is always an honor — and pitching in to help prep for such a meaningful community event made the day even sweeter. 💙

📅 Red, White & Bluegrass – June 13
Think live bluegrass, great food, cold drinks, local vendors, line dancing, a bourbon tasting, and an incredible raffle with prizes like Morgan Wallen field tickets, a signed Justin Moore guitar, a PS5, and more. It’s a full day of summer fun, and every ticket supports Boulder Crest’s life‑changing programs.

📸 Swipe through to see our crew in action — a lot of sweat, even more smiles, and mountains of mulch!

🚀 AI adoption isn’t a tech problem. It’s a people problem.
 
Our team attended the Carahsoft GovExperience Summit yesterday to discuss the practical realities of scaling AI in the public sector.
Here are 4 mission-critical takeaways from the sessions:
1️⃣ Adoption is the real hurdle. The hardest part of AI isn’t the code; it’s culture. Convincing employees that AI is a tool to elevate their work—not replace it—is key.
2️⃣ Map your bottlenecks. Before deploying new tech, identify your operational friction points. Course-correct early to pave a smooth path for AI integration.
3️⃣ Reverse-engineer your mission. AI is useless if it delays or disrupts your core outcomes. Start with your mission goals and work backward to find the right tool.
4️⃣ Robotics & AI are merging. The future of robotics is deeply tied to autonomous decision-making, shifting how we think about readiness and efficiency.
 
Special shoutout to the panels on “Leveraging AI to Enhance Efficiency and Readiness” and “The Business of Government: Aligning Services to Mission Outcomes” for driving these crucial conversations.

The hardest part of AI isn’t building it. It’s adoption. ⚙️👩🏼‍💻 That’s why this next step for Cornerstone matters so much.

We’re excited to welcome Dave Cook as our new Chief Innovation Officer as we continue expanding our focus on AI, advanced analytics, human-machine teaming, and cognitive solutions.

Dave brings decades of experience across the Intelligence Community, AI strategy, education, and emerging technology — but what stood out most to us is his belief that innovation only matters if people can actually use it effectively.

As the industry evolves, we’re focused on staying close to the mission while helping customers navigate what AI adoption really looks like in practice.
