Fractional Executive

A fractional executive is an experienced executive who works part-time across multiple companies, providing senior leadership without the cost of a full-time hire. Sometimes called part-time CFO/CTO/CMO, fractional VP, or fractional leader. Engagements typically run 10-30 hours per week per client. The model is increasingly common for CFO, CTO, CMO, and VP-level roles where the work is genuinely part-time at certain company stages and where the company can't justify a full-time hire yet but needs senior-level expertise. It is a structural alternative to full-time executive hiring that fits specific situations well and other situations poorly.

The fractional model:

• Engagement: typically 10-30 hours per week, with the executive working concurrently for 2-5 different companies.
• Compensation: hourly or monthly retainer (often $200-500/hour or $5,000-25,000/month per client), sometimes with small equity grants (0.1-0.5% in lieu of cash).
• Scope: defined by the engagement letter; typically focused on specific deliverables and ongoing advisory rather than full executive scope.
• Duration: ranging from 3 months (bridge engagements) to multi-year (ongoing fractional CFO relationships are common at small companies that never grow large enough to justify full-time CFO).

Where fractional executives work well:

Pre-Series-A or small-team companies:

• The work genuinely is part-time (a 10-employee company doesn't need a full-time CFO; a fractional CFO at 15 hours/week covers the actual finance work).
• Cash budget can't justify full-time executive compensation.
• The company needs senior expertise but not full-time presence.

Bridge engagements during transitions:

• Existing executive leaves; fractional executive bridges until full-time replacement is hired.
• New company stage requires expertise the existing team doesn't have; fractional executive provides it while team develops or hires.

Specialized expertise the company doesn't need full-time:

• Specific functional expertise (e.g., security expert, regulatory expert) needed periodically but not full-time.
• Strategic advisor relationships that go beyond traditional advisor roles.

Common fractional roles:

• Fractional CFO: most common. Small companies use fractional CFOs through Series A and sometimes through Series B.
• Fractional CMO: useful for B2B companies that need marketing strategy and direction but can't justify full-time CMO yet.
• Fractional CTO: useful for non-technical founders pre-MVP or post-Series-A companies with senior engineering team but needing CTO-level strategy.
• Fractional VP Sales: less common but works for B2B companies that need sales leadership while the team is small.
• Fractional Head of People/HR: useful at 25-100 employees when HR work is real but not full-time.

Where fractional executives don't work:

• At scale-up or later stages: when the executive role is genuinely full-time, fractional engagements aren't enough. The company needs dedicated leadership.
• For roles requiring deep cultural embedding: certain roles (CEO, head of product, head of design at design-driven companies) require dedication that part-time doesn't provide.
• When the company has high-velocity decision making: fractional executives can't be present for all the decisions; the company needs to evaluate whether part-time bandwidth fits its operational rhythm.

Finding fractional executives:

• Specialized firms: companies like Chief Outsiders, Bench Accounting, RoseRyan provide fractional executives as a service.
• Independent consultants: many senior executives have moved into fractional work after leaving full-time roles. Network-based hiring is common.
• Marketplaces: Toptal, Upwork (less common for executives), and specialized fractional platforms.

What founders get wrong: Either underusing fractional executives (defaulting to full-time hires before they're justified, burning cash unnecessarily) or overusing them (trying to operate scale-up-stage companies with fractional executives when full-time leadership is needed). The right discipline: assess honestly whether the role is full-time work at your current stage. If part-time work, fractional is the better economic choice. If full-time work, hire full-time. Don't let cost-savings instinct drive you to use fractional executives in situations where the workload requires full-time dedication.

FAQ

What is a fractional executive?
An experienced executive who works part-time across multiple companies (typically 10-30 hours per week per client), providing senior leadership without the cost or commitment of a full-time hire. The model is common for CFO, CTO, CMO, and VP-level roles where the work is genuinely part-time at certain company stages.

When do fractional executives make sense?
At pre-Series-A or small-team companies where the work is genuinely part-time and the cash budget can't justify full-time compensation. During bridge engagements between full-time executives. For specialized expertise needed periodically but not full-time. Most commonly fractional CFO at companies through Series A or B.

When should I transition from fractional to full-time?
When the workload grows beyond what fractional can cover. The signs: fractional executive is consistently working more than the engagement scope, important decisions are delayed waiting for their bandwidth, the team needs more dedicated leadership presence. Transition to full-time when the work justifies it; don't try to scale past the fractional executive's natural ceiling.
