Verifying an EF founder
A founder proves they are with EF using a link they generate themselves. Three checks tell you it is genuine.
Every real verification link is on founders.joinef.com. Check it in the address bar before you trust anything on the page.
A link on any other domain is not an EF verification, however much the page looks like the one below.
Ask the founder for their link. They create it, they control what it says, and they can switch it off at any time. It opens to a page like one of these, and which one tells you the offer they qualify for.
EF offers usually come in two, one for founders still in the programme (before EF funding) and one for founders EF has funded (after EF funding). The two pages look different on purpose. A founder whose company has since exited or ended still reads as after EF funding, so they stay eligible for your funded offers; a founder who left before any EF funding reads as before EF funding.

}A link that has expired or been switched off returns {"verified": false}, and always with a 200, so an unknown code and an expired one look the same to a script.
