Slack - Onboarding Flow

Top findings

1. 1The reCAPTCHA image challenge (select all images with cars) fires mid-signup and forces a multi-click visual puzzle that breaks momentum at the highest-intent moment in the funnel — before any value has been delivered.
2. 2Email verification requires the user to leave the browser entirely, navigate to their inbox, locate the Slack confirmation code email, copy the 6-character code 'YIU-BZ8', and paste it back into the app — a full P-Gap interruption that is the single largest drop-off risk in the flow.
3. 3A 'Start with Business+' paid upgrade screen fires immediately after workspace creation, before the user has sent a single message or experienced any product value — this misplaced commercial prompt trains users to dismiss Slack's pricing and reduces long-term upgrade intent.
