Get your technology led right — without a full-time CTO.

Fractional and interim CTO leadership for growth-stage companies. Three decades scaling engineering organizations — from two engineers to more than 250, through multiple acquisitions — with unusual depth where the stakes are highest: regulated data, legacy and physical-world integration, and AI transitions you can't afford to get wrong.

Who I work with

I partner with a small number of growth-stage companies at a time:

  • Funded startups and scale-ups that need a CTO's judgment before they can justify a CTO's salary.
  • PE and VC portfolio companies needing steady technical leadership through a transition, turnaround, or build.
  • Established small-to-mid companies modernizing — especially in regulated industries (insurance, healthcare, government) and integration-heavy and industrial operations, where I've spent most of my career.

How I can help

Four ways to work together, starting with a low-risk, fixed-scope diagnostic that leads into ongoing leadership.

Technology Diagnostic

A fast, fixed-fee assessment of your technology, team, and roadmap, with a written plan you can act on immediately. The best place to start.

Fractional CTO

Ongoing, part-time technical leadership on a monthly basis.

Interim CTO

Near-full-time leadership through a defined transition or critical build.

Advisory

Board-level and founder-level counsel when you need judgment, not hours.

Why me

  • One accountable executive. You get a single senior person who owns the outcome end to end — strategy, architecture, delivery, and the infrastructure and security underneath.
  • A builder who's actually scaled. I've grown engineering organizations from two people to 250+, through multiple acquisitions, and led early cloud migrations at multi-billion-transaction scale — deploying to AWS when the only path to production was a command line.
  • Depth where the stakes are highest. SOC 2, insurance, healthcare, and government; plus a career that started on the factory floor with industrial controls, so I understand systems that have to work in the physical world.
  • Still hands-on with today's tools. I build with current AI models and agentic tools every day, so the modernization and AI calls I help you make come from someone doing the work — not narrating it from the outside.

Not sure where your technology actually stands?

Book a call and we'll talk it through. If it makes sense, the first step is usually a Technology Diagnostic — a fixed-scope read on your tech, team, and roadmap, with a written plan you keep.
