The single decision that defines a productised service is what you say no to. The temptation is to take any work that comes in; the discipline is to keep the offer narrow enough to deliver consistently.
The wedge filters:
- Repeatable. You've done this same kind of work for 5+ clients with broadly the same scope. You can describe what they got in one sentence.
- Bounded. A clear "done" — the deliverable is something you can put on a checklist, not "we improved their marketing."
- High-value per hour. Your time delivering it should be worth at least $200/hour of equivalent agency rate; ideally $400+.
- Low custom-research per project. If every project starts with two weeks of discovery, you don't have a productised service yet — you have consulting that ends in delivery.
Good wedges that have built solo-to-team-of-3 businesses recently:
- Webflow / Framer site builds (14-day delivery, $4-12k).
- SOC 2 readiness sprints (8-week, $25-50k).
- ICP research + cold outbound list build (2-week, $3-8k).
- Brand identity in a sprint (5-day, $8-15k).
- Migration projects (Mailchimp → Loops, Salesforce → HubSpot, Stripe billing rebuild) at fixed price.
Bad wedges that turn back into agencies:
- "Marketing for B2B SaaS" — too broad, ends up custom every time.
- "Fractional CTO" — value is in judgement, not deliverables; doesn't productise.
- Anything where the customer's situation determines >40% of the work.
The exercise: write the offer in one sentence with a number in it. If you can't, the wedge isn't tight enough yet.
