How I Help

Jonathan

Hiring a full-time CFO is a major commitment—both in cost and structure. The fractional CFO model gives you a better option. You get direct access to senior financial leadership—strategic, hands-on, and deeply experienced—without adding to your payroll or overhead.

Whether your business needs a CFO a few hours a week or a few days a month, fractional support means you only pay for the expertise you need. It’s an efficient, flexible way to:

  • Solve complex financial challenges without hiring full-time

  • Support investor readiness and capital strategy

  • Strengthen operations, controls, and reporting

  • Coach founders and align leadership—without creating internal politics

It’s the fastest way to add real firepower to your team—at a fraction of the cost of a full-time hire.

Flexible, high-impact CFO leadership tailored to your company's needs.

Executive Coaching

Trusted coaching for first-time C-suite leaders — and the CEOs who lead them.

I help new executives understand the unique demands of leading from the top — including how to manage up (reporting to their CEOs and boards) and manage down (leading their direct reports and aligning cross-functional teams). This coaching equips both the executive and the CEO to work more effectively together and raise leadership capacity across the company.
