A college project has one user (you, or your team) and no deadline pressure beyond a demo date. A startup version of the same idea has real users, real support requests, and a cost structure that suddenly matters.
What actually changes
- Reliability now has a cost attached — a bug that was funny in a demo is a support ticket and a refund request in production.
- Cost control stops being optional — a college project's API bill was probably a rounding error; a startup's is a line item someone has to justify.
- You need at least one other person who can operate the system when you're unavailable — a hackathon project only ever needed you.
What genuinely doesn't change
The core technical judgement — knowing when to use RAG versus fine-tuning, how to evaluate honestly, how to keep a system debuggable — transfers directly. The hard part of the transition is operational discipline, not new technical knowledge.
