You only need to upload the Founder Agreement to successfully enroll into the program. Please make sure you upload the PDF version when you log into the Founder Institute. The website will not accept any other format.
If you see that the option to upload the agreement has disappeared, then you have successfully uploaded the agreement. You can find the Founder Agreement here: http://fi.co/agreements. The warrant and board consent form will be required once the Startup Legal and IP session has passed.
