Hello @ Adam Wade,
Thanks for reaching out to Microsoft Q&A.
It definitely sounds like your personal MSA isn’t being bound to a Startup Profile in the Founders Hub tenant—which is why you see a successful auth but then get bounced back to the signup page over and over. Let’s try a couple of things, and if those don’t work we’ll gather some details and escalate this to the Microsoft for Startups Concierge team:
Try the Founders Hub URL instead of the signup page
• Go directly to https://foundershub.startups.microsoft.com/login
• Sign in there with your MSA and see if you land on your dashboard.
Verify your MSA’s tenancy
• If your MSA isn’t yet associated with any Azure AD tenant, spin up a free one: – In the Azure portal (https://portal.azure.com) go to Azure Active Directory → Create tenant. – Invite your MSA as a guest or add it as a user.
• Then try logging into Founders Hub again—you should no longer get the “personal account” bounce.
Confirm you’re part of a Startup Profile
• If you already have a referrer code or investor–backed profile, ask that Admin to: – Sign in to the portal → Offers → Manage members – Re-invite your personal MSA and assign you the appropriate role (Member or Administrator).
• Once you’re explicitly in the tenant, the loop should stop and you’ll hit your dashboard.
