What is an MVP and Why Do You Need One?
Definition
An MVP (Minimum Viable Product) is the simplest version of your product that delivers real value to customers. It is not:
- A prototype (that doesn't really work)
- A beta product (that's further along)
- A "bad" version (it must work well)
Why MVP?
1. Validation Before Investment
- Test if customers really have the problem
- Test if your solution works
- Learn before the big investment
2. Faster to Market
- First-mover advantage
- Earlier feedback from real users
- Iterate faster
3. Less Risk
- Less money burned if it doesn't work
- More data for investor conversations
- Pivot possible before too much invested
What Belongs in the MVP?
In:
- Core feature (the one that creates value)
- Good UX (not beautiful, but usable)
- Tracking (to learn)
Out:
- Nice-to-have features
- Scaling
- Edge cases
- Perfect design

Should I code myself or outsource?

MVP vs. Prototype vs. Beta - what's the difference?
Prototype: Non-functional, shows concept. MVP: Minimally functional, delivers real value. Beta: Feature-complete, being polished.
