About us
At Tandem, we believe winning in government isn’t about running the same old plays—it’s about building smart strategies, showing real value, and working together as one team.
We are a team of product builders, entrepreneurs, and government veterans, who have lived the same challenges our clients face. With experience across all three branches of government and the private sector, we bring a rare blend of policy insight, technical expertise, and business strategy to every engagement.
What makes us different? We don’t just consult—we embed. We work as an extension of your team, bringing a learning mindset and fresh perspective to each challenge. We combine deep knowledge of procurement, policy, and growth with hands-on experience developing products, building partnerships, and navigating compliance.
Our approach is simple: show, don’t tell. From acquisition consulting and growth strategy to solutions engineering and proposal support, we design engagements around your unique goals. We don’t stop at advice—we roll up our sleeves, craft demos, coach your team, and build the infrastructure you need to succeed in the public sector.
At Tandem, we don’t roll solo. We win together.

What People Are Saying

GOVTECH FOUNDER
“
We weren't sure if Tandem would be able to help us given that we were still early in our thinking and that my co-founder is a former government executive. But Tandem helped focus the conversation about where we might be most effective from a product-market fit in the near term, and helped us get a sense of where we might encounter pitfalls. We left with clarity, next steps, and a new sense of urgency—without the chaos.
