Is there anyone who would like share their thoughts?

I spent 6 months building InvestSwipe (fintech app for beginners to discover stocks).

Built in isolation.

Zero feedback.

Just me and my assumptions.

Then 3 people actually tested it.

Here's what happened:

BEFORE TESTING, I thought:

- Dividend filter is the killer feature

- Need more technical indicators

- Should add portfolio analytics

- UI needs more polish before launch

AFTER 3 TESTERS, I learned:

- "The swipe is fun" (nobody mentioned dividends)

- "I found stocks I'd never heard of" (discovery > analysis)

- "Some cards are incomplete" (ship faster, fix obvious gaps)

- Nobody cared about UI polish

My entire roadmap changed.

I was building features USERS DON'T CARE ABOUT.

I was ignoring things USERS ACTUALLY VALUE.

This is why you launch before you're ready.

Not because "done is better than perfect."

Because you literally don't know what matters until users tell you.

Question for other founders:

How many beta testers did it take before you completely changed direction?

I'm at 3. Wondering if I need 10, or if these 3 are telling me everything I need to know.

For context: It's a "Tinder for stocks" app - swipe to discover investments, practice with fake money. Built for people who get overwhelmed by traditional investing apps.
