We have named products after reviewers. If you have an audience that trusts your ear, tell us what you make and we will talk about what we could do together.
There is no fixed package and no application form. A person reads what you send.

Who it is for
Reach is not the thing we are counting. A reviewer read by four hundred people who buy on their word is worth more to us than a channel that will not remember the product next week.
If you want a referral rate rather than a project
That is the affiliate programme, and it is a better fit: published rates from 5% to 18%, a tracking link, a 14-day cookie, and no conversation needed to start. This page is for building something.
What we can talk about
We are not going to publish a tier list, because what we agree has depended entirely on the person and the project. These are the things that have actually been on the table.
The usual starting point. Yours to keep, and yours to be rude about — we have published reviews that were not kind.
Hearing a set before launch, sometimes early enough that what you say still changes it.
The rarest of these and the reason the page exists: a set you shape and that carries your name. Four have shipped.
Through the affiliate programme, which has published rates. It can run alongside anything else here.
A discount your community can use, which tends to matter more to people than another giveaway.
Answers from the engineers rather than from a press kit, when you are writing something technical.
None of the above is automatic and none of it is a promise. It is what there is to discuss when you write.
Questions
We do not publish a threshold, and we are not going to invent one. Send the link and let the work speak — a small, specialist audience that acts on your recommendation is the thing we are looking for.
Sometimes, and it is usually where a collaboration starts. It is not automatic and it is not what this page is promising. Tell us what you would do with one.
No. A review nobody believes is worth nothing to us. Say what you actually heard.
No. The affiliate programme is a published, self-serve arrangement — apply through UpPromote, get a link, earn 5% to 18% on referred sales. This page is for projects, and the two can run together.
That has happened four times, and every one of them began as a working relationship rather than as a request. Start by reviewing something.
Normally within 48 hours on a working day. We are Mon to Fri on GMT+8.
