My startup is a place where freelancers and small business owners can anonymously exchange data about when their business customers pay them vs agreed terms. I'm in closed beta and I haven't tried the whole "Show HN" thing yet. ;)

I would be wanting to reach lots of UK business press as the whole late-payment problem is something that affects companies all over the country and is often in the press.
Anyway, I'll sign up and take a look. Thanks!
