    How the Success Score is calculated

    Five weighted components, scored 0–100 each. The score is a screening signal for this business model in general — not a verdict on your specific version of it in your market.

    Capital efficiency · 20% weight96/100

    Needs up to $2,000 to open the doors.

    Speed to first revenue · 25% weight94/100

    Typical gross margin around 70%.

    Time load · 15% weight74/100

    Needs about 25 hours a week to work.

    Opportunities

    • Recurring retainers, remote, and the incumbent firms are turning away small clients.
    • Cash-flow positive from the first client — no inventory, no build phase before revenue.
    • Retainers convert one good delivery into 12 months of predictable income.
    • Pricing power grows with a named niche: same work, 2–3x the rate once you are "the X person".
    • Fast feedback loop: you learn whether people pay within a month, before sunk cost sets in.

    Risks

    • Revenue is capped by your hours until you hire and delegate delivery.
    • Client concentration: losing one retainer can erase a third of monthly revenue.

    The first four moves

    1. 1Write the offer as one sentence: outcome, timeline, price. No menus.
    2. 2List 30 named prospects who have the problem this week and contact all 30.
    3. 3Sell the first engagement before you build a website or a brand.
    4. 4Deliver once manually, then document the process into a repeatable scope.

    Kill criteria — decide in advance

    • No paying customer after 6 weeks of consistent effort.
    • Fewer than 3 of your first 20 qualified conversations show urgency about the problem.
    • You cannot repeat the acquisition channel that produced the first three customers.

    Who this fits

    Best for founders with numbers & process strengths who can commit around 25 hours a week and hold out 4 weeks before the first paying customer. Expected year-one revenue: $3K–12K/mo.
