Account problems stop users before they reach value in signup, login, verification, or billing. Product problems appear after activation, when users enter but soon leave.
A launch postmortem is a short review that sorts access failures from demand failures using evidence. It helps a team fix the blocker that actually stopped growth. It uses first-week funnels, support tickets, and retention cuts.

Where did users stop?
Map the path from install to first value. Mark signup start, account created, verified, logged in, paid, and first key action. Split pre-activation stops from post-activation churn.
Baymard Institute's 2025 checkout research finds 19% of shoppers abandon when asked to create an account, reported in Baymard's cart-abandonment data. Treat high signup loss as an account suspect. Treat clean activation plus fast exit as a product suspect. Use the same date range for all cuts to avoid false splits.
- signup started versus account created
- verification sent versus verified
- login tried versus login succeeded
- billing started versus paid, then activated versus returned
Is access blocking activation?
Account failures leave clear traces. Look for reset loops, expired codes, blocked social login, and device-specific faults. Compare new and returning users. If new users stall while returning users act normally, suspect onboarding.
If both groups fail at login, suspect the auth system. Reproduce each path on a clean install. Test weak networks, new numbers, and changed emails. Log every error code with time and device.
Does account deletion pass review?
Apple requires apps that allow account creation to also let users start deletion inside the app, described in the Apple Developer announcement. The rule applied to submissions since January 31, 2022, with enforcement extended to June 30, 2022. A missing delete path can stall review even when the core app works.
Build deletion where users expect it, near profile or settings. Confirm what data stays, what deletes, and how long each takes. Test delete, re-signup, and restore before launch week.
Do activated users stay for a reason?
CB Insights' review of 483 startup failure post-mortems names lack of market need as the leading cause, summarized in CB Insights analysis of startup failures. Running out of cash appears as the final symptom, not the root cause. Use that split when activated users leave fast. Product strain shows after access works.
Users activate, try once, then vanish. They report no need, they never repeat, and they invite no one. Check retention by cohort, not by total installs. Compare promise, first task, and repeat use. If the first task feels weak, fix audience, offer, or onboarding before buying traffic.
How do you decide what to fix first?
Google's SRE Book calls for blameless reviews that focus on system causes and assume good faith, explained in Google's postmortem culture chapter. List contributing causes, not culprits. Keep the tone plain and direct.
Score each failure by reach, proof, and fix cost. Act in this order. Assign one owner, one fix, and one recheck date before you close the note. Keep the log with the funnel snapshot that proved the choice.
- fix blocked signup, login, verification, and payment first
- fix missing deletion path and support backlog next
- test product change with one cohort before wide release
