Blumira

Blumira is the cybersecurity company for the mid-market that existing enterprise security tools forgot. Founded in Ann Arbor in 2018 by Steve Fuller, Matthew Warner, and Patrick Garrity, all former Duo Security engineers, Blumira built a detection-and-response platform designed specifically for the IT teams at small and mid-sized organizations that do not have dedicated security operations centers.

The technical approach is practical. Most SIEMs and XDR platforms are built for large enterprises with dedicated SOC analysts. Blumira stripped that model down to what a mid-market IT generalist can actually operate. Pre-built detections, guided response playbooks, and straightforward onboarding let a two-person IT team get meaningful detection and response coverage in days rather than months. The company has grown steadily through that positioning and raised more than 30 million dollars from M12, Mercury, and others.

Blumira is the clearest example of Ann Arbor's security flywheel in action. Duo Security alumni going on to build the next generation of security companies in the same city is the sort of thing that most tech hubs aspire to and rarely achieve. Blumira's founders explicitly built in Ann Arbor because the talent pool, the cost structure, and the local security community were the right conditions for the company they wanted to run.

The office is downtown, which means everyone on the team lives within a short commute of the kind of restaurants, coffee shops, and public spaces that a growing security startup wants nearby. For security engineers, detection engineers, and SaaS operators who want to work on a product that is genuinely helping underserved IT teams keep their organizations safe, Blumira is one of the most interesting small-and-mid-market security seats in the country.
