We Reviewed 100 Launches: Here's What Teams Missed
The same five gaps show up across almost every early-stage launch, regardless of stack or team size. None of them are hard to fix. All of them are easy to miss under deadline pressure.
1. Payment webhooks with no signature verification
The most common single gap. A checkout flow works perfectly end-to-end — but the webhook handler that confirms payment never checks that the request actually came from Razorpay or Stripe. Anyone who finds the endpoint can fake a "payment succeeded" event.
2. Database access wider than intended
For Supabase apps specifically: at least one table with Row Level Security disabled, or a policy that unintentionally allows unrestricted reads. Teams assume RLS is on by default. It is not, and AI code generators rarely add it without being explicitly told to.
3. Zero rate limiting on AI/LLM endpoints
Apps with a chat feature or AI-generated content almost never rate-limit it before launch. The first cost spike is usually the first time anyone notices.
4. No plan for what happens on failure
The happy path is tested. What the user sees when a network call times out, a webhook fails, or two writes collide — usually isn't. This is the gap that turns a small bug into a support ticket flood.
5. Nobody actually tried to break it
Every one of these launches had been manually clicked through by the founder or team. None had been tested by anything actively trying to find the failure mode — which is exactly the gap between a demo and an adversarial review. See AI Pentesting.
The pattern behind the pattern
None of these five gaps require deep expertise to catch. They require someone (or something) to specifically go looking for them, instead of confirming the features you already built work as intended. That's the difference between testing and reviewing readiness.
