Former enterprise CIOs, available now
These aren't consultants learning on your dime. They've run technology at scale, managed nine-figure budgets, and sat in the boardroom. Now they work fractional, which means you get their judgment without the overhead.
Strategy and procurement, separated by design
Most technology vendors have a conflict of interest—they recommend solutions they also sell. We don't. A fractional CIO advises on strategy while a separate procurement team sources the best tools, regardless of margin.

Network
The Mary Sumner CIO Roundtable keeps everyone sharp
Our CIOs aren't isolated contractors. They're part of an active peer network—the Mary Sumner CIO Roundtable—where they share problems, debate solutions, and stay current on what's actually happening in mid-market technology. That network becomes your advantage.
- Peer learning and real-world problem solving
- Continuous exposure to industry trends and challenges
- Accountability to a community of peers, not a sales quota
Why senior talent chooses fractional work
After running IT at scale, most CIOs don't want another full-time role. They want variety, control over their time, and the chance to solve real problems without politics. Fractional work lets them do exactly that—pick engagements that matter, work with companies that respect their judgment, and stay sharp without the corporate noise.
