The Dayo charity pledge: at least 20% goes back
Medstack commits at least 20% of relevant annual surplus to UK charities, and for selected providers may donate 100% of the affiliate earnings they generate. Dayo operates under that pledge from day one.
Support already given across the network runs to 16 charities and counting, published as a public record with Charity Commission links so every donation claim can be verified independently rather than taken on trust. See the full pledge and the charities supported.

Why a comparison site gives money away
Because of where this network came from. Monj grew out of community-made price lists on Reddit and the unpaid legwork of Facebook group members comparing real checkout prices to stop each other being overcharged. That work was done by patients, for patients, for nothing. Building a business on top of it and keeping every penny would have missed the point entirely.
The pledge is the answer to a fair question: if this site earns commission from weight-management medicines, who benefits? At least a fifth of what is left after costs goes to UK charities, and for some providers the entire commission is donated.
How the pledge works
- At least 20% of relevant annual surplus is committed to UK registered charities.
- For selected providers, 100% of affiliate earnings generated through their listings may be donated.
- Donations are published as a public record, with Charity Commission links, so the claims on this page can be checked by anyone.
- The pledge is network-wide, covering Dayo, Monj, iGovy and Ogovy.
What the pledge does not buy
It buys no leniency. A provider that fails our verification checks is removed whether or not their commission was funding donations, and no provider can pay for position, wording or inclusion. The pledge is what happens to money we have already earned honestly; it is not a justification for earning it any other way. Our full funding position is on the about page.

Every charity supported is a UK registered charity that you can look up on the Charity Commission register, and the company behind the pledge is Medstack Ltd, company number 16439872, on the Companies House register. We would rather you checked than believed us.
