Same seniority, very different commitment. The honest comparison across cost, ramp time, scope, and equity. Plus the bridge model: how a fractional engagement often becomes the path to the right full-time hire.
A fractional CMO works one to three days per week on a contract retainer, typically for six to eighteen months. A full-time CMO is a permanent employee working five days per week, with salary, benefits, and usually equity. The seniority and quality of strategic thinking is the same. The commitment, cost, ramp time, and shape of integration are very different. Most B2B companies are better served by a fractional CMO until post-Series-B.
A fractional CMO is a senior marketing leader who runs a B2B company's marketing on a part-time, ongoing basis. One to three days per week. Six to eighteen months. They own positioning, GTM, channel mix, team structure, and operating cadence. They sit in the standup, run the marketing meeting, write the brief, sign off on the campaign. They are accountable for marketing outcomes, not for filling a chair.
The model is structurally a contract retainer. No salary line. No benefits. No equity. The fractional CMO operates as an external senior leader who happens to be deeply embedded for the duration of the engagement.
A full-time CMO is a permanent senior executive on payroll. Five days per week. Multi-year commitment. Salary, benefits, equity, board representation, full participation in the executive team. The full-time CMO is the long-term owner of the marketing function and represents marketing inside every strategic conversation: board meetings, fundraising, M&A, IPO process, exec offsites, hiring across the org.
The model is structurally an employment relationship. The CMO has skin in the multi-year game. They build the team they will run for years. They make hiring and budget calls with a longer horizon than a fractional ever could.
| Dimension | Fractional CMO | Full-Time CMO |
|---|---|---|
| Time commitment | 1 to 3 days per week | 5 days per week, plus on-call |
| Engagement length | 6 to 18 months, retainer-based | Multi-year, employment relationship |
| Cost structure | Day-rate retainer, no benefits, no equity | Salary + benefits + equity package |
| Annual cost (Europe) | ~50 to 60% less than full-time at comparable seniority | €150,000 to €300,000 base salary; fully loaded with charges patronales (~1.5x) lands at €225,000 to €450,000 before equity |
| Ramp time | 1 to 3 weeks from engagement to running | 3 to 6 months hiring cycle, then 3 months ramp |
| Hiring cost | None: no recruiter fee, no notice period to clear | Executive search fee, typically 25 to 30% of first-year base, or €30,000 to €60,000 retainer |
| Exit cost and risk | Contract end, no severance, no labor law exposure | French CDI severance, rupture conventionnelle, potential litigation; six-figure exits common |
| Board and exec presence | Marketing review present; not in every exec topic | Full executive team; represents marketing everywhere |
| Long-term commitment | None beyond the agreed retainer | Years; aligned to vesting and strategic horizon |
| Best fit | Pre-Series-B; uncertain marketing shape; bridge to full-time | Post-Series-B/C; scaled team; IPO path; board-level role |
The salary line is the visible cost of a full-time CMO. The full cost is bigger and the risk profile is different.
Time to start. Hiring a senior marketing executive takes three to six months from "we should hire one" to a candidate signing the offer, then another two to three months of notice period. A fractional CMO who is available can be in the next standup. For a B2B company where marketing is the bottleneck right now, the difference between "running this month" and "running in nine months" often matters more than the day-rate gap.
Hiring cost. Executive search for a CMO role typically runs 25 to 30 percent of first-year base, or a €30,000 to €60,000 retained fee for a European boutique firm. A fractional CMO carries no recruiter fee. The first conversation costs nothing, and the engagement starts in a week.
The fully-loaded salary, not the headline. A €150,000 base in France is rarely the actual cost. With charges patronales (employer contributions to social security, pension, healthcare, and unemployment), the fully-loaded cost runs roughly 1.5 times the base. A €150,000 base lands at around €225,000 all-in. A €200,000 base lands near €300,000. Equity is on top. A fractional CMO is invoiced as services, with no charges, no benefits line, no equity dilution, no severance exposure on the P&L. When the comparison is on fully-loaded cost rather than day-rate vs salary, the gap is even wider than the standard pitch implies.
Exit risk, especially in France. French CDI executive roles carry meaningful labor-law exposure. Severance scales with seniority and tenure, rupture conventionnelle negotiations can stretch for months, and disputed exits can litigate. A six-month-old full-time CMO who isn't working out can cost the company low six figures to exit, even when the decision is mutual. A fractional CMO engagement just ends on the agreed notice period. No severance line on the P&L, no labor-law process, no relationship damage.
None of this argues against ever hiring a full-time CMO. It does argue against hiring one before the function is shaped enough that the role description is stable, the brief is defensible, and the company is ready to absorb the cost and risk of a permanent senior hire.
Pick a fractional CMO when the company needs CMO-level thinking now but cannot yet justify a full-time hire, or when the shape of the marketing function is still being figured out.
Pick a full-time CMO when the marketing function genuinely needs five-day-a-week leadership and the company is at a stage where that level of permanent ownership pays back.
One of the most common patterns: a B2B company hires a fractional CMO for twelve to eighteen months, knowing from day one that the engagement is also a path to a full-time hire. The fractional CMO clarifies positioning, builds the playbook, hires or coaches the team, and ends the engagement by helping recruit (and onboard) the right full-time CMO.
This pattern works because the hardest part of hiring a full-time CMO is writing the right job description. A fractional CMO who has run the function for a year knows exactly what kind of person should sit in the chair next, and can defend that profile against the board, the search firm, and the candidate pool. The result is a better hire, a shorter ramp for the incoming CMO (the playbook is already built), and a function that doesn't reset every time leadership changes.
Discuss the bridge expectation in the first conversation. It works best when both sides are aligned from the start. Some fractional CMOs prefer to stay fractional and will turn down bridge engagements. Others actively prefer them. The mismatch is what causes friction later.
A fractional CMO works one to three days per week on a contract retainer, typically for 6 to 18 months. A full-time CMO is a permanent employee working five days per week, with salary, benefits, and usually equity. The seniority and scope of strategic thinking is the same. The commitment, cost, and integration shape are very different.
A full-time CMO in Europe typically costs €150,000 to €300,000 in salary plus benefits and equity. A fractional CMO is paid on a day-rate basis, scaling to the engagement size. An ongoing fractional engagement at one to two days per week typically lands at 50 to 60 percent less annual cost than a full-time CMO with comparable seniority, with no equity dilution and no long-term commitment.
Sometimes, depending on the fractional CMO's model. Many treat fractional as the model they want to run long-term. Others see fractional as a bridge: come in for twelve months, build the function, help hire the eventual full-time CMO, transition out. Discuss this expectation in the first conversation. The bridge model works best when both sides are aligned on it from the start.
When the marketing function needs five-day-a-week leadership: a large marketing team to manage, regular board representation, deep cross-functional executive presence, multi-year strategic planning, or IPO-track preparation. Typically post-Series-B for B2B SaaS, often post-Series-C for European companies. Hiring a full-time CMO before the function actually needs that depth of leadership is the more common mistake than the reverse.
Hiring a senior marketing executive typically takes 3 to 6 months of search plus 2 to 3 months of notice period. Executive search retainer is usually 25 to 30 percent of first-year base, or €30,000 to €60,000 for a European boutique. Exit costs in France are meaningful: a CDI executive let go inside the first 18 months can cost low six figures in severance and rupture conventionnelle. A fractional CMO has no recruiter fee, no notice cost, no severance exposure: the contract just ends.
If you are not sure whether you need a fractional or a full-time CMO, a thirty-minute call is the fastest way to find out. Often the answer is fractional now, with the next conversation being who the right full-time hire is twelve months from now.
