What We Do

Raft is a digital consulting firm with niche expertise in the rapid delivery of modern, user-first, scalable, and data-intensive digital solutions. We accelerate the missions of our federal partners through human-centered design (HCD) and agile development practices, bringing deep technical expertise in DevSecOps, Kubernetes management, cloud-native microservice architectures, and secure, open source delivery. We put our people and our culture first. We work with some of the smartest, hardest working experts in their field. We owe it to them to make sure our team is free of meaningless restrictions and internal politics so they can focus on what they love, finding innovative solutions. We build off the Open-Source and resist vendor lock in. That way you’re not paying us to reinvent the wheel, our solutions play nice with others and are always adaptable. We know digital innovation doesn’t always operate during bank hours, so neither do we. (It's also why we don’t dress like bankers.) We aren’t afraid to go the extra mile or put in the extra time to find a solution. We get it right the first time; we won’t waste our time (and your money) trying to fix something that’s fundamentally broken. It’s kind of like making an exceptional cup of coffee, if the beans are roasted wrong, it doesn’t matter how much pumpkin spice you dump in your cup, it’s still not going to taste great. And above all else we’re up for a challenge; it’s in our DNA. Ask us about something that’s never been done, or better yet something that can’t be done, and we’ll find a way to do it. It’s just who we are. If you need a partner that’s looking toward the future and not the past, don’t go traditional, go Raft.

Why Work With Us

Raft partners with public agencies to solve hard complex problems that impact the lives of millions of Americans. We work hard to make it easy for humans to connect with data.
