Thanks for your question. The email address is only used to verify that you are with the company. We'll send you an invitation code once there is quorum, which you can use to sign up for an anonymous account. We don't link this account and your corporate email. We just mark your corporate email as taken, so no one else can sign up from the same email. The unfortunate side effect is that you would not be able to recover your password in case you forget it.
