The three common structures
| Structure | How it works | Fits |
|---|---|---|
| Monthly retainer | Fixed fee for a set hour band | Most funded companies |
| Equity or blended | Small vesting grant, reduced cash | Pre-revenue and early stage |
| Session-based | Priced per strategy review | Quarterly board input only |
Hourly billing is uncommon. It makes clients hesitate before sending the short message that would have prevented a costly decision — which is precisely the value the retainer is buying.
What drives the price
- Depth and relevance of the advisor's operating record
- Seniority of who is being advised — founder, CMO or full board
- Cadence: a monthly session versus fortnightly plus ad-hoc access
- Whether board attendance and written recommendations are included
- Response expectations between sessions
Equity for advice — the fine print
Equity arrangements work when the scope, cadence and vesting schedule are written down and there is a clean exit clause. The failure mode is an advisor who quietly stops engaging while the grant keeps vesting. A one to two year schedule with a review point, and a defined minimum commitment, solves most of it.
The payback test
Advisory is cheap relative to the decisions it touches, so the test is not the retainer size — it is whether the advisor is changing decisions. A useful check at the quarterly review: name two decisions that went differently because of the advisory relationship, and estimate what the alternative would have cost. If nothing comes to mind two quarters running, the cadence or the fit is wrong.
How it compares
Advisory sits at the lowest-cost end of on-demand leadership. A fractional CMO costs considerably more because the engagement includes ownership of strategy, team and delivery. Read what a strategic advisor actually does before comparing the two on price alone.
