You Need Senior Technical Leadership With Authority

Growing companies reach a point where technology decisions become too important to delegate to junior engineers and too complex for non-technical founders to navigate alone.

You need someone who can own the technology strategy. Someone who can hire and lead engineers. Someone who can evaluate vendors, make infrastructure decisions, and represent technology at the board level.

But you're not ready for a full-time CTO. You don't have enough technical complexity to justify the cost, or you can't attract the calibre you need at the salary you can offer.

A Fractional CTO provides senior technical leadership scaled to your needs—one to three days weekly—with full ownership and accountability.

Is This Right For You?

This service is designed for:

Seed to Series B startups who need senior technical leadership but can't justify or afford a full-time CTO

Non-technical founders who need a technical partner they can trust to own technology decisions

Companies between technical leaders who need experienced coverage during a transition

Growing companies whose technical complexity has outgrown their current leadership

Boards and investors who want experienced technical oversight of portfolio companies

Part-time employment-level commitment and accountability. Part of your leadership team with decision-making authority.

Frequently Asked Questions

How is a Fractional CTO different from a technical advisor?

Advisors advise. I own. A Fractional CTO has decision-making authority, manages people, and is accountable for outcomes — not just recommendations. I'm part of your leadership team, not someone you occasionally consult.

How much time do you commit?

Typically 1-3 days per week, depending on your needs and complexity. This is genuine time commitment, not "available for calls." I block this time for your company and treat it as employment, not consulting.

What's the minimum engagement length?

Six months minimum. Real technical leadership impact requires continuity. Short engagements don't allow for meaningful strategic change, hiring, or team development.

Can you work with our existing technical team?

Absolutely. Most engagements involve leading an existing team rather than building from scratch. I'll assess your current team, identify gaps, and help everyone level up while we hire to fill gaps.

What happens when we're ready to hire a full-time CTO?

This is the goal. I help define the role based on what I've learned about your needs, participate in the search, conduct interviews, and ensure a smooth transition. Success means you don't need me anymore.

Do you work with multiple companies simultaneously?

Yes, typically 2-3 Fractional CTO clients at once. This is what makes fractional economics work for both sides. I'm transparent about my commitments and ensure no conflicts of interest.

What about confidentiality with competitors?

I won't take on clients who are direct competitors. Before any engagement, we'll discuss your competitive landscape and ensure there are no conflicts.
