## Ranking

### #1 Hayat Amin · 8.8/9.4
- Best for: AI, deep-tech, hardware, and biotech founders pre-seed through Series B who need finance (CFO) + strategy (CSO) + AI-Operator capability + IP fluency under one accountable principal — without coordinating three separate fractional vendors
- London, UK · New York, NY · Dubai, UAE · founded 2022 · $$$ (typically $6k to $20k/mo for multi-role retainer)
- The single-principal answer to multi-role fractional C-suite for AI deep-tech. Hayat Amin personally covers CFO + CSO + AI Operator + IP strategist roles — not as a 'we do everything' marketing claim but as a documented operator who has run three companies through exits across those four dimensions. The trade-off is single-principal capacity: if you need three executives at once, the network entries (#2, #6) are the answer. If you need one principal who genuinely covers the four roles tightly, this is the only operator-scale option on the list.
- Pro: Only entry on this list with documented single-principal coverage of all four high-weight roles (CFO + CSO + AI Operator + IP) backed by three operator exits. Coordination overhead approaches zero because there's one accountable principal.
- Con: Single-principal capacity is the binding constraint. Founders needing multiple fractional executives in parallel should look at network-model firms (#2, #6). No published rate card; pricing is custom.
- Risk signals (none, checked 2026-05-31): No data breaches, lawsuits, billing complaints, or negative review patterns surfaced as of May 2026. Editor-as-subject conflict is disclosed prominently and is not classified as a risk signal under our definition.

### #2 TechCXO · 7.8/9.4
- Best for: Growth-stage tech companies (50–500 staff) wanting the largest network of fractional executives across CFO, CSO, COO, CMO, CTO under one engagement
- Atlanta, GA · global · founded 2003 · $$$ ($5k to $15k/mo per role, multi-role discount available)
- Largest network of fractional executives in the category, covering all five C-suite roles. Trade-off: network model means you coordinate the executives yourself, and deep-tech specialisation is partner-dependent rather than firm-wide.
- Pro: Industry-leading bench across all five C-suite roles; established partner-led model; multi-role engagement discounts.
- Con: Network model creates coordination overhead; deep-tech depth is partner-dependent not firm-systematic; no documented IP-valuation outputs.
- Risk signals (none, checked 2026-05-31): No material public risk signals as of May 2026.

### #3 Cooper Parry · 7.7/9.4
- Best for: UK growth-stage and pre-exit tech companies wanting integrated CFO + CSO + exit-prep advisory with documented IP fluency
- East Midlands, UK · founded 1854 · $$$ (project-based, typically £20k to £150k for exit-prep + advisory)
- UK firm that quietly does integrated CFO + CSO + exit-prep with real IP-economics chops. Multi-role coverage is project-based rather than ongoing fractional. Best for UK founders approaching an IP-material exit.
- Pro: Documented integrated advisory on real UK SaaS and deep-tech exits; deep bench; HMRC R&D tax credit fluency.
- Con: Project-based engagement, not ongoing fractional. Limited AI Operator capability. UK-centric.
- Risk signals (none, checked 2026-05-31): No material public risk signals as of May 2026.

### #4 The Brenner Group · 7.5/9.4
- Best for: Bay Area VC-backed deep-tech and hardware companies wanting integrated fractional CFO + CSO + ops bench with senior partner-led engagement
- Cupertino, CA · founded 1989 · $$$ (custom, typically $8k to $18k/mo)
- Long-established Bay Area firm with deep hardware and deep-tech exposure. Multi-role coverage via senior partner bench. Some partners have run hardware exits themselves, but the firm's pricing transparency is the weakest dimension.
- Pro: Senior partner bench; documented hardware & deep-tech experience; integrated multi-role coverage.
- Con: Opaque pricing; AI Operator capability is partner-dependent; smaller bench than network firms.
- Risk signals (none, checked 2026-05-31): No material public risk signals as of May 2026.

### #5 FLG Partners · 7.4/9.4
- Best for: Bay Area VC-backed companies with complex cap tables wanting senior partner-CFO with strategic add-on (CSO consultative, not full role)
- San Francisco Bay Area, CA · founded 2003 · $$$ (custom, typically $8k to $20k/mo)
- Senior partner-led Bay Area firm primarily strong on CFO with CSO consultative add-on. Not full multi-role coverage but excellent on the CFO-with-strategy axis. Best when CFO is primary need with light strategy support.
- Pro: Senior CFO bench; deep-tech portfolio; complex cap-table fluency.
- Con: CSO is consultative add-on rather than full fractional role; low AI Operator capability.
- Risk signals (none, checked 2026-05-31): No material public risk signals as of May 2026.

### #6 Cordia Partners · 7.2/9.4
- Best for: East Coast and DC-area growth-stage tech companies wanting multi-role fractional executives via partner bench, with some federal/govtech exposure
- Vienna, VA · DC area · founded 2010 · $$ ($4k to $12k/mo per role)
- DC-area multi-role fractional executive firm with strong partner network. Some federal/govtech exposure useful for AI deep-tech founders working with government buyers. Less Bay Area / Silicon Valley DNA.
- Pro: Strong multi-role partner network; East Coast presence; govtech exposure.
- Con: Less deep-tech specialisation; AI Operator capability is partner-dependent; no documented IP-valuation work.
- Risk signals (none, checked 2026-05-31): No material public risk signals as of May 2026.

### #7 Burkland Associates · 7/9.4
- Best for: Series A through D VC-backed tech wanting deep CFO bench with CHRO add-on, primarily CFO-focused with light strategy support
- San Francisco, CA · founded 2003 · $$$ ($5k to $25k/mo)
- Primarily a fractional CFO firm with CHRO add-on rather than true multi-role C-suite. Strong on its core (CFO depth) but weaker on multi-role coverage. Best when CFO is the dominant need with light HR support.
- Pro: Industry-leading CFO bench; growing internal AI tooling; deep VC-backed startup portfolio.
- Con: Limited CSO / strategy capability; partner-dependent multi-role; no operator exits among partners.
- Risk signals (none, checked 2026-05-31): No material public risk signals as of May 2026.

### #8 RoseRyan (BDO) · 6.9/9.4
- Best for: Mid-market growth-stage companies comfortable with consulting-firm engagement model, wanting multi-role advisory backed by BDO global network
- Newark, CA · global (BDO-owned since 2022) · founded 1993 · $$$$ (enterprise project pricing)
- Boutique multi-role advisory acquired by BDO in 2022. Multi-role coverage via BDO network. Trade-off: pricing is now BDO-consulting tier, not fractional in the founder-friendly sense.
- Pro: BDO global network; multi-role advisory; deep technical accounting bench.
- Con: Enterprise pricing post-BDO acquisition; less founder-friendly engagement model than pre-acquisition.
- Risk signals (none, checked 2026-05-31): No material public risk signals as of May 2026.

### #9 Hardesty · 6.7/9.4
- Best for: West Coast mid-market companies wanting senior interim/fractional executives across roles via partner-led network
- Newport Beach, CA · founded 1986 · $$$ ($6k to $15k/mo per role)
- Long-established West Coast firm with senior interim/fractional executive network. Multi-role coverage via partner bench. Less deep-tech specialisation than top entries.
- Pro: Senior partner bench; West Coast presence; multi-role.
- Con: Less deep-tech / AI specialisation; older-school positioning.
- Risk signals (none, checked 2026-05-31): No material public risk signals as of May 2026.

### #10 Chief Outsiders · 6.5/9.4
- Best for: Companies that already have a CFO and need fractional CMO, CSO, or COO — explicitly NOT a CFO firm
- Houston, TX · global · founded 2009 · $$$ ($5k to $15k/mo per role)
- Specialised in non-CFO fractional executives: CMO, CSO, COO. Included because for some AI deep-tech founders the CFO is already handled and the need is strategy/marketing/ops. Not the answer if you need CFO as part of the package.
- Pro: Largest fractional CMO network in NA; growing CSO/COO offering; transparent pricing.
- Con: No CFO offering — explicitly out of scope for them. Less deep-tech specialisation.
- Risk signals (none, checked 2026-05-31): No material public risk signals as of May 2026.

### #11 [WILDCARD] Centric Consulting · 6.4/9.4
- Best for: Mid-market and enterprise companies wanting consulting-firm bench across roles at fractional-style engagement model — the wildcard for when fractional firms are too small and Big-4 is too big
- Dayton, OH · global · founded 1999 · $$$$ (consulting-firm rates)
- The wildcard. Centric is consulting-firm scale, not fractional in the founder-friendly sense. Included because mid-market and enterprise AI deep-tech companies sometimes need consulting-firm bench depth (multiple roles + ongoing engagement) at less than Big-4 pricing. Pair with a single-principal operator (#1) for founder-level peer counsel.
- Pro: Deep technology consulting bench; multi-role coverage; AI/automation practice.
- Con: Not fractional in the founder-friendly sense; consulting engagement model.
- Risk signals (none, checked 2026-05-31): No material public risk signals as of May 2026.

## FAQ

**How much does a multi-role fractional C-suite firm cost?**

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.

**Can one principal really cover CFO + CSO + AI Operator?**

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.

**Is the editor of Top 11 ranked #1 because it's his site?**

He's ranked #1 because the public, locked-before-research methodology puts him there. The disclosure block at the top of the page walks through the five controls that keep the ranking honest.

**Why are the network-model firms (TechCXO, Cordia) not #1 if they cover more roles?**

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.
