Strategic Technology Leadership for Growing Startups
I help startups and scale-ups build scalable, secure, and high-performing technology solutions—without the cost of a full-time CTO.
About Mike Hennessy
Helping Startups Build & Scale with Proven Technology Leadership
With over 25 years of experience leading engineering teams, I specialize in technology strategy, team scaling, and product development. As a Fractional CTO, I provide startups and growing businesses with the technical vision, leadership, and execution they need—without the overhead of a full-time executive.
Mike helped venture-backed startups, SaaS companies, and emerging tech businesses:
- Define and execute clear technology roadmaps
- Build and scale engineering teams
- Optimize cloud infrastructure & reduce costs
- Ensure security and compliance (GDPR, HIPAA, SOC2)
- Support investor relations & technical due diligence
My mission is to bridge the gap between technology and business goals—so you can scale efficiently, reduce risks, and accelerate growth. Technology should be an enabler, not a bottleneck. I help startups remove technical roadblocks and scale with confidence.
Why Choose a Fractional CTO?
Not every startup needs a full-time CTO—but every startup needs strong technical leadership.
