Researched profile. The figures here are modelled by us from public information, published with the sources they were drawn from. How we research.
Nobody has priced this business. What follows is a model — a base multiple moved by what the public record supports — applied to trailing-twelve profit, and it prices Doctor Jupiter on Amazon US alone.
Indicative valuation: $8,532,221 — 3.3× a trailing-twelve net profit of $2,585,522, scored as of Sep 2026. Trailing-twelve net profit at a modelled multiple. Doctor Jupiter on Amazon US only — their own site is excluded, unread.
The positives are what has been built: over 10,000 reviews at 4.6 stars across the largest listings, a spotless seller record, an enrolled brand store and three measured Christmases, each bigger than the last. The negatives are the shape of the year and of the catalogue: December carries well over a third of the trailing year, all of it on Amazon US, and one kit carries most of the revenue — a kit that factories already list near-identical versions of.
Four inputs are inferences rather than reads. Sourcing, catalogue shape and the differentiation level are questionnaire answers taken from the public record, and fulfilment is read from the listings’ fees; Brand Registry is firmer, since Amazon gates the brand store behind it. The age is dated from the first Doctor Jupiter kit in April 2022, not the two Learnabee board books listed in 2021. All of them are the first things to put to the owner.
