Product validation via pre-sales

I recently came across content that suggested validating an idea via pre-orders > MVP.

Although we spent time building our MVP, I'm excited to try this approach.

Here's a snippet from the article:

"With tech, it comes down iterating and testing both of these assumptions:

1. Will the product actually do what I think it will (technology / science / etc).
2. Will anyone want it?

The cool part is both of these can be figured out fairly quickly if you do it right.......

One word of caution:

It does NOT require an MVP (Minimum Viable Product).

It really comes down to a few simple frameworks that I’ve created to help you validate your ideas… and generate the confidence (and initial funding) you need to go all in.

Here they are:

1. Idea: Problem, Pain, Passion
2. Validated Research
3. Clickable Prototype
4. Pre-Sales"

Would love the community's take on the pre-sale > MVP
approach and any feedback on our product/pre-sale!

Thank you!
