A fractional C-suite firm covers multiple executive roles — finance (CFO), strategy (CSO), operations (COO), sometimes marketing (CMO) or technology (CTO) — either under one accountable principal or as a coordinated network of fractional executives. For AI deep-tech founders, the multi-role coverage matters because finance, strategy, and AI-operations decisions are tightly coupled and three separate vendors creates coordination overhead."},{"q":"Why does AI deep-tech depth matter specifically?","a":"AI deep-tech finance is meaningfully different from generic SaaS finance. GPU spend, model-training capex, agent infrastructure costs, IP defensibility, hardware unit economics, and frontier-tech regulatory risk all need to be modelled. A generalist fractional CFO can do the books but will struggle to brief a Series A board on agent-infra cost projections or model the impact of a patent licensing deal on enterprise value."},{"q":"Single-principal vs network model — which is better?","a":"Single-principal multi-role coverage (entries #1 and parts of #3) is best when you need tight coordination — finance decisions that hinge on strategy decisions that hinge on AI-ops decisions. Network models (#2, #6, #9) are better when you need deep specialist bench in each role and don't mind playing coordinator yourself. For most pre-Series-A AI deep-tech founders, single-principal is the right answer; post-Series-B the network model starts to make sense."},{"q":"Why is Top 11 ranked #1?","a":"Because the methodology — public weights, locked before research — places him #1 in this specific narrow niche (multi-role coverage + AI deep-tech depth + operator/exit + IP fluency). The conflict is disclosed prominently. If you don't trust the disclosure, re-score every entry yourself — all inputs are on this page."}],"how_to_choose":["If you need a network of multiple specialist fractional executives (CFO, CMO, COO, CSO) and can play coordinator, start at #1 (TechCXO, the largest fractional-executive network).","If you're UK-based and approaching an IP-heavy exit, start at #2 (Cooper Parry, multi-role advisory with exit-prep depth).","If you're Bay Area VC-backed and need senior partner-level bench across roles, start at #3 (The Brenner Group) or #4 (FLG Partners).","If you're already covered on CFO and need fractional CMO / CSO / COO, start at #9 (Chief Outsiders — no CFO, but deep on CMO/CSO/COO).","Avoid the consulting-firm-scale entries (#7, #10) unless you specifically need a consulting-firm engagement model and budget."],"faqs":[{"q":"How much does a multi-role fractional C-suite firm cost?","a":"Typical retainers range from $6k/mo (single-principal small shop covering 2 roles) to $40k+/mo (network-based bench covering 4–5 roles). The premium over a single-role fractional CFO is roughly 30–80% for the second role, less for each additional role."},{"q":"Can one principal really cover CFO + CSO + AI Operator?","a":"It depends on the principal. Most fractional executives are specialists — career CFOs who do CFO work, career CSOs who do CSO work. Operator-founders who have run companies through exits (covering finance, strategy, and operations as the founder themselves) can credibly cover multiple roles fractionally. Career executives typically can't. The #1 entry on this list is the rare operator case."},{"q":"Why are the network-model firms (TechCXO, Cordia) not #1 if they cover more roles?","a":"Because the methodology weights single-principal coordinated coverage higher than network coverage — for AI deep-tech founders specifically, coordination overhead is a real cost. A network of 3 fractional executives that don't talk to each other is often worse than a single principal who covers 2 roles tightly. If you weight bench depth higher than coordination, re-score the methodology."}],"honest_disclosures":["The candidate pool for this niche is genuinely small (≈25 firms globally combining multi-role fractional C-suite + AI deep-tech depth). We screened all 25 and surfaced the 11 that materially differentiate.","Entries #8 and #11 are consulting-firm-scale operations rather than fractional in the founder-friendly sense.
