FAQ

Frequently Asked Questions

  • A fractional CTO provides part-time strategic technology leadership to help companies:

    • Align technology strategy with business goals
    • Design scalable system architecture
    • Implement security best practices
    • Build and mentor high-performing engineering teams
    • Establish efficient development processes

    This allows growing companies to access experienced technical leadership at a fraction of the cost of a full-time CTO, while getting guidance on critical technology decisions and team development.

  • As a fractional CTO, I focus on empowering your engineering team through:

    • Strategic guidance and coaching
    • Knowledge transfer and education
    • Building self-sufficient capabilities

    My goal is to help your team level up quickly and become increasingly independent, making the most of our time together.

  • Actually, working with multiple companies is a key advantage. As a fractional CTO, I have:

    • Solved diverse technical challenges
    • Worked with various business models
    • Led different types of engineering teams
    • Gained broader experience than typical full-time CTOs

    This wealth of experience means I can identify solutions faster and help you avoid common pitfalls.

  • You might benefit from a fractional CTO if your company:

    • Faces technical challenges beyond your team's expertise
    • Needs strategic guidance for technology decisions
    • Can't justify the cost of a full-time CTO

    Most companies only need a fractional CTO for 6-10 months to help level up their engineering teams and establish independent workflows. The goal is to build self-sufficient teams that can operate effectively without constant technical leadership.
