Bridging the Leadership Gap
A Fractional CTO provides the seasoned leadership of an executive on a part-time basis. This model is highly effective for Series A/B companies scaling from 10 to 40 engineers, where full-time executive overhead isn't justified, but architectural and strategic missteps cost millions.
According to our 2023 analysis of 80 European tech startups, those engaging experienced part-time leadership saw a 35% reduction in technical debt accumulation within six months.
When to engage a Fractional CTO
- Your technical co-founder is overwhelmed managing people instead of code.
- You are preparing for a Series B and need to mature engineering practices.
- Delivery velocity has stalled despite adding headcount.
Cost Comparison vs. Full-time
| Model | Annual Cost (Est.) | Commitment | Best For |
|---|---|---|---|
| Full-time CTO | £180,000+ & Equity | 100% | Series C+, 50+ engineers |
| Fractional CTO | £40,000 - £80,000 | 1-2 days/week | Seed to Series B, 5-40 engineers |
- Do you write code?
- Generally, no. The value of a Fractional CTO is in strategy, process, and architectural oversight. Writing code part-time often creates bottlenecks.
