Strong ROI scenarios: £2m-£20m revenue companies needing technology strategy but lacking budget for full-time senior technical leadership. Cost savings can be reinvested in engineering talent and infrastructure.
Cost-effective scaling: Startups and scale-ups that need technical architecture decisions without full-time executive overhead. Particularly effective for companies with complex technical challenges or platform development.
Technology transformation: Companies undergoing digital transformation, cloud migration, or technical platform modernisation. Fractional CTO expertise often pays for itself through improved technical efficiency.
Budget optimization: Companies spending £200k+ on technology consultants who need strategic oversight and technical ownership. Fractional CTO cost often provides better value than multiple specialist consultants.
Seed stage (£0-£2m ARR): 1-2 days/week, £60k-£100k annual cost. Focus on technical architecture, hiring strategy, and foundational technology decisions.
Series A (£2m-£10m ARR): 2-3 days/week, £100k-£150k annual cost. Technology scaling, team building, platform architecture, and engineering culture development.
Series B+ (£10m+ ARR): 3+ days/week, £150k-£200k annual cost. Complex architecture decisions, large team management, technical strategy, and enterprise technology requirements.
Enterprise transformation: Project-based or 2-4 days/week, £120k-£250k annual cost. Legacy system modernisation, cloud migration leadership, and technical transformation oversight.
