SaaS idea validation checklist
Use this checklist before writing production code. WrapperCheck automates the structured first-pass in about a minute — then you validate the strongest ideas with real buyers.
- 1Write a one-sentence problem statement — who hurts and why today?
- 2Define your target customer narrowly (not "small businesses").
- 3List 3–5 existing competitors or alternatives, including DIY workarounds.
- 4Estimate pricing and rough cost per customer (API, infra, support).
- 5Score wrapper risk: what stops a competitor from copying you in a week?
- 6Run a structured validator like WrapperCheck for a first-pass Wrapper Score.
- 7Interview 5–10 potential buyers on the ideas that score well.
- 8Decide: Build, Refine, or Avoid before writing production code.

Common validation mistakes
- Building thin wrappers — products competitors can copy in a weekend without unique data, workflow, or distribution.
- Skipping economics — ignoring API costs, margins, and whether the business works at your target scale.
- Vague customers — "small businesses" is not a target customer. Narrow until you can name who buys and why.
- Only using generic AI — unstructured chat opinions without consistent scoring or competitor analysis.
When to Build, Refine, or Avoid
- Build — the idea has enough signal to test further.
- Refine — the core direction may be useful, but positioning, customer, moat, or execution needs work.
- Avoid — the idea currently looks too weak, generic, or hard to defend.
