Fractional COOs in Ann Arbor Making Things Happen in 2025

Ann Arbor Interim Chief Operating Officers to Know

Ann Arbor has always punched above its weight. Home to world-class research institutions, a growing tech and startup scene, and a robust community of mission-driven organizations, this Southeast Michigan hub is teeming with innovation—and complexity. And when complexity rises, so does the need for operational leadership. That’s where fractional COOs come in.

Today’s most forward-thinking companies are turning to fractional Chief Operating Officers (COOs) to bridge the gap between ambition and execution. Whether it’s a university spinout scaling its product, a nonprofit formalizing its systems, or a growth-stage SaaS company refining its go-to-market strategy, fractional COOs offer on-demand executive leadership with flexible commitment.

At Digital Reference, we believe in amplifying the professionals who drive real, verifiable outcomes—often behind the scenes. We exist to make the talent ecosystem more efficient, human, and transparent, and we’re proud to feature the operators helping Ann Arbor’s organizations move forward.

Our Methodology

To curate this list of Ann Arbor-based fractional COOs, we applied the following criteria:

• Location: Based in or actively working with organizations in Ann Arbor, Ypsilanti, and surrounding areas
• Role Type: Offering fractional, interim, or part-time COO services
• Background: Demonstrated experience in operations, strategy, organizational design, or executive leadership
• Visibility: Accessible via public platforms (LinkedIn, websites, or firm affiliations)
• Alignment: Professionals who match Digital Reference’s ethos of radical transparency, structured credibility, and impact-driven leadership

These are the folks turning strategy into systems, guiding teams through change, and putting process behind purpose.

Why Ann Arbor Organizations Are Turning to Fractional COOs

Ann Arbor and Southeast Michigan have always had a rich mix of academic innovation, entrepreneurial energy, and civic-minded leadership. Today, that mix is creating a new wave of organizations that need flexible, experienced operations leadership.

Why the fractional COO model works in Ann Arbor:

• Many companies are spinoffs from research labs or university programs—with founders needing help building the business side
• Nonprofits are modernizing and require strategic operations help without full-time overhead
• Startups are growing fast but aren’t ready for a full-time COO
• Founders need a thinking partner who can also execute

Fractional COOs step into the gap—translating mission into momentum.

What Makes a Great Fractional COO?

Beyond technical skills and experience, the best fractional COOs know how to:

• Embed quickly: They integrate into a team without disrupting its culture
• Lead and coach: They don’t just fix problems—they elevate internal leaders
• Simplify complexity: Whether it’s team structure, finance, or compliance
• Operate with empathy: Understanding that startups and nonprofits are inherently personal

They also know when to step back—designing themselves out of the system they help build.

Fractional leaders don’t always leave behind a title—but they do leave behind results. That’s why at Digital Reference, we’re building the infrastructure for them to:

• Capture verified outcomes and testimonials
• Organize work into a professional, portable portfolio
• Build a reputation based on truth, impact, and authenticity

We believe that in a world moving toward modular work, tools like Digital Reference will become essential for professionals who work across clients, sectors, and missions.
