Milly Books is built on a deliberate asymmetry: the seller side is anonymous and the buyer side is open. A seller can publish the shape of a book without naming themselves; a buyer publishes who they are and exactly what they want. The buyer profile is how the open side works — and it's what lets an anonymous seller choose, with confidence, which named buyer to engage.
This piece covers what's in a profile, the three surfaces it powers, and why the open-buyer design is a feature rather than an oversight.
§ 01 · What's in a profileAppetite, captured once.
A buyer builds the profile through a short wizard, and the structure mirrors the way slices are defined — the states a buyer operates in, the carriers they want, the lines of business they write, and the premium range they'll consider. Capturing it once, in a structured form, means the same appetite drives discovery and ranking everywhere on the platform without the buyer restating it. Each buyer holds a single profile, so there's one authoritative statement of what they're looking for.
§ 02 · Three surfacesWhere a profile shows up.
One profile, three jobs:
| Surface | Audience | What it does |
|---|---|---|
| Buyer database | Sellers in the app | Browse and filter active, named buyers |
| Public profile page | The open web | Lets sellers discover a buyer before signing up |
| Match ranking | The matching engine | Supplies the appetite each slice is scored against |
The public profile page is the demand-side equivalent of a storefront: a buyer's stated appetite, indexed and discoverable, so a seller can find the right counterpart even before creating an account. Inside the app, the buyer database is the filterable directory of that same demand. And every match the platform surfaces draws its appetite from the profile — so a complete, specific profile produces sharper rankings than a sparse one.
§ 03 · Why buyers are openThe asymmetry is the point.
It would be easy to make both sides anonymous. Milly Books doesn't, because the two sides have opposite risks. A seller exploring an exit has real downside if word leaks — staff, carriers, and clients can all react to a rumored sale — so the seller side is anonymous by default. A buyer has the opposite incentive: the more clearly they state who they are and what they want, the more good supply finds them. Making the demand side open and named lets an anonymous seller evaluate a real, accountable counterparty instead of negotiating into the dark. The asymmetry isn't a gap; it's what makes a confidential sale to a known buyer possible.
Anonymous sellers, open buyers. The design lets the side with leak risk stay private and the side that benefits from visibility be found — so a confidential seller can still choose a named, accountable buyer.
