Testing monetization in MVP - is Buy Me a Coffee a good idea?

Heey everyone,

I'm part of the team that's building Lifetoon, an AI-native platform for episodic visual storytelling in its MVP stage.

We wanted to validate the idea as quickly as possible, so we launched before finalizing the Stripe integration. That means users can access the product, but we can’t charge them yet.

As a temporary workaround, we added a Buy Me a Coffee link at the end of the user flow to test if there’s a willingness to pay.

And, I'm curious - has anyone here tried something similar during the MVP phase? If you've used this approach, what was your experience like? Did it work, did it not?
