It would be too much of a deliberate affront to refuse to let them even attend. And not all the leads startups have are from the audience at DDay. Since there are so many investors here, they often get introed to investors before DDay through some other connection.

Also, zero is probably an overstatement. It would have been better to say epsilon. Because most of these investors I would take money from if the alternative would be to shut down the company.
