Frequently Asked Questions

How do you work with teams?

I work both strategically and hands-on, integrating as a partner across your organization. At the executive level, I align technology with business strategy and handle stakeholder communication. With engineering teams, I provide technical architecture guidance, hands-on mentoring, and help navigate challenges like AI adoption or scaling systems. The depth of engagement depends on your needs - from strategic advisory to embedded technical leadership - but the goal is always tangible results, not just advice.

What's the typical engagement length?

Each engagement is strategically tailored to your specific business objectives. We can start with a focused 4-6 week collaboration to address your most critical priorities and demonstrate immediate value. This approach allows us to build momentum while we assess the full scope of your needs.

What if our team lacks AI expertise? Do we need to hire AI specialists?

You don't need to hire AI specialists. I work with your existing team to develop AI capabilities through hands-on mentoring, practical training, and gradual skill building. We start by integrating tools that enhance current workflows, enabling your team to deliver immediate business value without learning entirely new skill sets. This approach builds confidence and expertise organically while generating measurable results for your business.

Why fractional CTO vs hiring full-time?

A fractional CTO gives you immediate access to 10+ years of CTO-level expertise without the 3-6 month hiring process. You get the strategic guidance and technical leadership you need right now, with the flexibility to scale up or down as your business evolves. It's the difference between waiting months to fill a critical gap versus having an experienced CTO starting next week.

Do I need to commit long-term?

No long-term contracts required. We can start with a focused engagement to address your most pressing challenges and demonstrate value. Many clients begin with one tier and adjust based on their evolving needs - scaling up during critical growth phases or stepping down once systems are stable. The goal is flexibility that matches your business reality.

What if we already have a VP of Engineering?

A fractional CTO complements your VP of Engineering, not replaces them. While your VP owns day-to-day execution and team management, I provide strategic oversight, architectural guidance, and experience navigating challenges they may be facing for the first time - like AI adoption, scaling architecture, or board-level technical communication. Think of it as an experienced mentor and strategic partner for both your VP and your business.
