Someone just sold a $3,000 vintage synthesizer on Reverb – in 12 minutes.
A solo woodworker on a tiny craft marketplace just booked six months of custom orders.
What’s Their Secret?

Finding Your Golden Niche (The $10M Question)
The Sweet Spot Formula – Not all niches are created equal. The best ones sit at the intersection of:
PASSION × PAIN × PURCHASING POWER = PROFIT
Passion Test
Do they join groups, follow creators, or tattoo it? Then it’s a niche worth chasing.
Pain Test
What do they vent about on Reddit, rate 1-star, or call “impossible to find”? That’s your niche gap to fill.
Purchasing Power Test
Do they spend $500+, buy premium basics, and treat it as an investment? That’s a profitable niche.

The Niche Marketplace Mindset
Remember: You’re not building the next Amazon. You’re building the first you.
Success Principles to Live By
Obsess Over Your Community
Their problems become your features. Their feedback becomes your roadmap. Their success becomes your success.
Quality Over Quantity, Always
Better to have 100 sellers who love you than 1,000 who tolerate you.
Solve Real Problems
If your marketplace doesn’t make someone’s life significantly better, it won’t survive.
Build Relationships, Not Just Transactions
The best marketplaces feel like communities where business happens, not businesses where community is an afterthought.
Stay Niche Until You Own It
Resist the urge to expand until you absolutely dominate your chosen space.

Your niche is waiting. Your community is ready. Your marketplace empire starts today.
