Fractional executives (CFO, CMO, CPO, CTO) can bridge the gap between needing senior expertise and being able to afford a full-time hire.
A fractional executive is a senior operator (typically 15-25 years of experience) who works with 3-5 companies simultaneously, giving each 1-3 days per week of their time. Used well, they solve the seed-to-Series-A problem where you need C-level thinking but can't yet afford or justify a full-time hire. Used badly, they become expensive advisors who don't own outcomes. The difference is entirely in how the engagement is scoped.
CFO: highest hit rate for fractional. Financial model, board reporting, fundraising prep, systems selection — all well-suited to part-time senior expertise. Typical engagement: 1-2 days/week, $8-15K/month. CMO/CPO: works when the scope is narrow (positioning refresh, launch strategy) but less well when execution is needed daily. CTO: rarely works well fractionally — engineering leadership is high-context and hard to time-share. Chief of Staff / COO: usually needs full-time presence.
You have a specific, scoped problem that needs senior expertise (fundraise prep, first pricing model, GTM strategy reset). You're pre-Series-A and can't justify a full-time exec at $250-400K all-in. The problem has a clear endpoint (6-12 months). You have someone internal who will absorb the knowledge and continue after. Fractional is a bridge, not a permanent solution.
You need someone to build a team — fractional executives rarely recruit well because they can't invest the time. You need daily operational leadership — this requires full presence. You're hoping fractional will 'audition' into full-time — sometimes works but usually the fractional is optimized for a portfolio and won't want to be full-time. You're using fractional to avoid making the harder decision to hire a full-time executive — this delays the decision without solving it.
Written scope of work with named deliverables and dates. Fixed monthly retainer (not hourly billing, which creates misaligned incentives). Direct line to CEO with weekly 1:1. Access to internal systems and team members appropriate to scope. Clear success criteria and end date (or renewal decision date). Equity typically not appropriate for fractional — this is a service relationship, not a founding one. Most engagements: 6-12 months, then transition to full-time hire.
Best source is portfolio-company introductions and investor networks — investors have seen many fractional engagements and know who delivers. Specialized platforms exist (Chief Outsiders for CMOs, Paro for CFOs, Bolster for various C-level) but curation quality varies. Reference-check the way you'd reference a full-time hire: talk to previous clients about specific outcomes and whether they'd re-engage.
