Two million in annual recurring revenue at twenty five dollars a month is six thousand six hundred and sixty seven customers. Set against thirty six million small businesses in the United States, that is eighteen thousandths of one percent.
So market size is not the question worth modelling. The question is whether roughly three hundred new customers a month can be acquired, every month, for two and a half years, at a cost that the contribution margin can carry. This page models that, and separates what is published from what is guessed. Mail and domain registration are deliberately out of scope: the pod needs authoritative DNS, nothing more.
Read the colours. Petrol values come from published rates or federal data. Amber values are assumptions with no source behind them, and every one of them is a thing to go and find out.
These are the populations, not the addressable market. The useful thing they show is how small a share of any of them the plan actually needs.
Two paths to the same revenue number. The first buys customers. The second already has them, which is the entire argument for building this inside an established host rather than beside one.
Any operator worth pitching will separate these two lists within about ninety seconds. Better to do it first.
At any sensible price above the mid twenties, contribution per pod carries a seventy five dollar acquisition cost several times over, and carries a hundred and fifty dollar one comfortably. The unit economics are not the problem.
The problem is throughput. Three hundred net new customers a month, sustained for two and a half years, is a marketing operation. An established host with a few hundred thousand existing customers reaches the same revenue by moving two tenths of one percent of its base per month, at a fraction of the cost, with the churn risk pointing the other way.
Read the commercial model for how the billing works, and the open questions for what is still unresolved.
