Common Questions
Everything you need to know about working with us
1How quickly can we start?
Most engagements start within 1-2 weeks after our initial discovery call. For urgent projects, we can mobilize faster.
2What does a typical engagement look like?
Fractional CTO/CFO engagements typically run 3-6 months at 2-3 days per week. MVP builds are fixed-scope at 8-12 weeks. We tailor every engagement to your stage and needs — no cookie-cutter packages.
3Do you handle both technical and financial leadership?
Yes. Many startups need both CTO and CFO guidance but can't justify two executive hires. We offer integrated leadership covering technology architecture, financial planning, and investor relations.
4What's your pricing model?
We work on retainer for fractional leadership (monthly commitment) and fixed-fee for defined projects like MVP builds or financial modeling. Fractional engagements start from £2,500 per month (CFO) and £3,000 per month (CTO) — typically 60-80% less than equivalent full-time hires.
