Fractional CTO - Chief Technology Officer

Build robust technology infrastructure with experienced fractional CTOs. Get the technical leadership you need to drive digital transformation and scale your technology operations.

What is a Fractional CTO?

A fractional CTO is a senior technology executive who works with your company on a part-time or project basis. They bring the strategic thinking and technical expertise of a full-time CTO without the permanent commitment and full-time cost.

Fractional CTOs are particularly valuable for growing companies that need technology leadership but aren't ready for a full-time executive hire. They can help with technology strategy, team building, architecture decisions, and digital transformation initiatives.

Typical Engagement

  • 20-60% time commitment
  • 6-18 month engagements
  • €120-400 per hour
