What to check before you apply
- 1. Check clarity: a stranger should understand what you make and for whom.
- 2. Update evidence: make traction, usage, revenue, and dates current and internally consistent.
- 3. Test every link: founder video and demo URLs should open without special access.
- 4. Get one cold read: ask someone unfamiliar with the company what remains confusing.
