Understanding CTO Rate Variation
IT Jobs Watch data shows significant variance due to small sample sizes (4-8 quoted rates in 6-month periods). The previous year UK median was £913/day, suggesting the current £535 median reflects specific job mix rather than market decline.

- Startup (Pre-Series A): £1,000-£1,500/day
- Scale-Up (Series A-C): £1,500-£2,000/day
- Enterprise (Post-Series C/PE): £2,000-£3,000/day
London rates at £1,350/day align with these benchmarks for scale-up level engagements.
