What The Work Covers

Inside the SF-5 engagement. Specific deliverables, specific cadence.

What the work covers

  • Weekly 60-minute strategy call with founder or CEO
  • Quarterly onsite (one full day in the Bay Area, typically the founder's office)
  • Monthly performance reporting in the format the board reads
  • Direct strategic ownership of positioning, pricing, GTM motion, and demand generation
  • Vendor and agency oversight on behalf of the founder
  • Hiring and team architecture recommendations as the marketing function scales
  • Bay Area VC ecosystem fluency: board reporting, attribution math, runway pressure

Format and cadence

  • Month 1: intake, current-state audit, 90-day priority lock
  • Months 2–3: priority execution oversight, weekly cadence, first quarterly onsite
  • Months 4–6: strategic compounding, hiring decisions, channel reallocation, quarterly board readout
  • Months 7–12: scale phase, succession planning if internal CMO hire is in scope, transition document
Anonymized Outcome

What the work actually produced.

A Series A AI infrastructure company in Mountain View hired SF-5 Fractional CMO instead of a full-time CMO at month four post-Series-A. By month nine, the founder had a clear succession brief for the in-house CMO hire, three quarterly board readouts in the format the lead investor wanted, and a 47% reduction in CAC payback period. The succession hire landed in month 11.

// Fit

This engagement fits when

  • Series A-B Bay Area startup ($5M–$30M ARR)
  • Founder ready to hand strategic ownership to a senior outside seat
  • 6–12 month commitment minimum (compounding takes a quarter to start, two quarters to read clearly)
  • Operating in or near the Bay Area for quarterly onsite cadence
// Not fit

This engagement does not fit when

  • Pre-Series A teams (SF-2 Lite Diagnostic-on-Retainer at $1,500/month is the right format)
  • Buyers wanting fractional execution rather than fractional leadership (look at retainer model elsewhere)
  • Series B-C teams needing a full marketing-function rebuild (SF-8 is the right format)
  • Operators who want monthly retainers with no strategic ownership transfer
Buyer Questions

Before you scope the engagement.

How is this different from a full-time CMO hire?

Cost structure and commitment. Full-time CMO is 6-month equity + base + signing + benefits, often $400K-$600K total comp first year, with a 12-18 month equity vesting cliff. SF-5 is $15,000-$20,000/month with no equity, no benefits load, no severance risk. It is the right format when the team is not ready to commit to permanent senior hire but needs senior strategic ownership now.

What does 'embedded' actually mean?

Weekly 60-minute strategy call with the founder. Quarterly full-day onsite. Slack and email access between meetings. Direct ownership of strategic decisions on positioning, pricing, GTM, and demand generation. The fractional CMO sits in the executive team's strategic context, not as an outside vendor.

Can we transition from SF-5 to a full-time CMO hire?

Yes. SF-5 includes succession planning when the team is ready to hire internal. Transition document covers hiring brief, first 90 days, retained relationships. Most SF-5 engagements run 6-12 months. Some run longer when the founder prefers the fractional format permanently.

Why a 6-month minimum?

AI compounding and strategy compounding both take 90 days to read clearly. One-month engagements produce no signal. Three months produce a measurable trajectory. Six months produce compounding. Founders sometimes want shorter; we decline shorter scope because it is set up to fail.

Is the SF-5 strategist the same person every month?

Yes. The same senior strategist runs the engagement end-to-end. No delegation to junior staff. No team handoff. The board reading the report and the founder on the weekly call see the same person who built the strategy.

How does this work for non-Bay-Area startups?

The quarterly onsite is the constraint. Bay Area operators get an in-room cadence; out-of-Bay-Area operators can request remote-only quarterly review. Most SF-5 fits land in the Bay Area for the in-room compounding effect. Out-of-area startups should evaluate fit on a case-by-case basis.

Does SF-5 include team building?

Strategic team architecture: yes (recommendations on what roles to hire, in what sequence, with what brief). Hiring execution: shared with the founder and any internal recruiter. Ongoing team management: not included in SF-5; that is internal to the founder. The seat is strategic, not operational.
