Guides

Accept portfolio or membership invites and understand connection requests.

Portfolio invitation (/join/portfolio/:token)

  1. Open the link from your email—tokens are single-purpose and time-bound.
  2. Sign in with an investor-eligible account or create one if prompted.
  3. Accept to attach your user to the inviting firm’s portfolio, or decline if it is the wrong relationship.

Investor membership invite (/join/investor-membership/:token)

Used when a teammate should join an existing investor account. Flow is similar: authenticate, accept, and you inherit that firm’s permissions.

Connection requests (ongoing)

Unlike one-off invites, connection requests are initiated inside the product after you already have an investor login. Companies accept or decline from Settings → Investors.
