About KnownDonor
Our mission
More and more people in the UK want a child with a known donor or co-parent: openly, honestly and at their own pace. KnownDonor makes meeting each other simple and human: discover, like and message for free, with clear information about UK law.
Why we do this
Many platforms ask for money before you can even send a message, and feel more like dating. We think the first contact should be free, and that safety and honesty belong at the very start.
What we promise
- Free to message: the basics stay free
- Cup, not bed: sex requests are banned
- Not a clinic, and we never handle sperm: you stay in control of tests, agreements and next steps
- Privacy: profiles are only visible to members
About me

I'm Duncan. I live in Winterswijk in the Netherlands. Besides this site I paint; the canvas in the photo is mine.
In the Netherlands I run BloeiWens, a free platform for known sperm donation. KnownDonor is the same idea for England: a calm, honest place instead of a subscription trap or something that feels like dating.
I'm not on the platform as a donor and I don't use it to match myself. I only build the website: you get to know each other. Intended mums start the conversation, and you can always block or report.
Questions about the site or your account are welcome by email. I read them myself.
