For founders and growing teams without a full-time CTO
Fractional CTO services
A fractional CTO is a senior technology leader who works with you part-time instead of as a full-time hire. Ours are NERDZ LAB tech leads with 12+ years of technical experience and 6+ years of leading technical teams and startups of different sizes and types. They take the decisions that are expensive to get wrong, such as architecture, AI, hiring and investor due diligence, backed by an 80+ person team that can build what we recommend.

Fractional vs full-time CTO: which do I need?
A full-time CTO makes sense once you have a large in-house team to lead every day. Before that, a fractional CTO gives you the same senior judgement on the decisions that matter.
Who will be my fractional CTO?
One of our senior tech leads, matched to your product, stack and stage. Each has 12+ years of technical experience and 6+ years of leading technical teams and startups of different sizes and types, and is backed by our whole team when the work needs more hands.
Can a fractional CTO work with my in-house team or another vendor?
Yes. A fractional CTO can lead your in-house engineers, guide another vendor or run a NERDZ LAB team, and often a mix of the three.
Can you help us prepare for technical due diligence?
Yes. We review the code, architecture and documentation that investors look at, fix the gaps that matter and prepare the answers for the technical part of due diligence.
What happens when we hire a full-time CTO?
We help you write the role and interview candidates, then hand over the architecture, roadmap and documentation, so your new CTO starts with a working system.
