Once the login appears, please login with the details you created in the signup form. You will see investors who have been matched with you in the first table (after they've granted permission to be shared) and you will see output of the feedback to your responses when you click on your profile icon. And you'll be able to also indicate there who you would like to proceed with.
The matching is run once per day at midnight, to allow us to establish and verify credibility of users. The feedback is instantaneous.
