October 25, 2025The Rarity Principle: Why Scarcity Signals Value in Tech Investments
Walking the floor at CoinExpo last week, I realized something: VC due diligence isn’t so different from hunting certified VG8 Sacagawea dollars. We’re both searching for technical excellence where others see only imperfections. The startups I back consistently do one thing well – they treat niche markets like numismatists treat low-grade coins: as systems to master, not anomalies to ignore.
The Low-Ball Coin Paradox: Ugly Ducklings or Unicorn Signals?
Why would anyone pay $500 for a “problem-free” coin that looks like it survived a garbage disposal? The same reason we invested early in:
- Plaid when everyone asked “Who cares about banking APIs?”
- GitHub while others chased enterprise SaaS
- Stripe during the consumer app gold rush
True tech scarcity hunting means building where others won’t dirty their hands.
Technical Due Diligence: The Inventory Architecture Test
When we tear into a startup’s codebase, we’re looking for the engineering equivalent of a certified coin pedigree. Can they handle rare finds at scale?
Stack Scarcity: Why Your Database Choices Determine Valuation Multiples
// Red flag: Novice inventory handling
app.get('/inventory', () => {
return db.query('SELECT * FROM coins WHERE grade < 20'); // Ouch
});
// VC-ready architecture
app.get('/rare-coins', async () => {
const cached = await redis.get('lowball:certified'); // Cache layer
if (cached) return cached;
// Partitioned query + read replicas
const results = await db.replica('SELECT * FROM coins
WHERE grade < 20 AND certified = true
ORDER BY rarity_score DESC LIMIT 50');
redis.setEx('lowball:certified', 300, results); // Async priming
return results;
});VC Truth: Teams that architect for scarcity early get 3x revenue multiples at Series A. Why? They've already solved the hard problems before scaling.
Market Positioning: From Niche Collectibles to Dominant Markets
Watch any obscure market long enough and you'll see our investment playbook unfold. Low-ball coins didn't jump from bargain bins to museum collections overnight. They followed the same path Brex used to build a $12B treasury platform:
The Scarcity Expansion Framework
- Phase 1: Own an unsexy problem (like tracking VF25 quarters)
- Phase 2: Build infrastructure others can't replicate (certification APIs)
- Phase 3: Expand to adjacent rarities (error coins → full numismatic stack)
Case Studies: Turning Niche Scarcity Into Venture-Scale Outcomes
Coinbase's Institutional Edge
While competitors fought over retail traders, Coinbase engineered bulletproof custody solutions - the equivalent of grading services for Bitcoin. Result? 83% of their trading volume came from institutions by Series D.
Heroku's Add-On Marketplace Masterstroke
Heroku turned obscure dev tools into gold by creating scarcity infrastructure:

=== Adding papertrail...
Plan: professional
Price: $7/month # Pure scarcity premiumThat "hard-to-find-as-a-service" model justified Salesforce's $212M check.
Actionable Takeaways for Founders
Want to catch a VC's eye? Do these three things:
- Measure your niche's friction points ("4+ hour search times for certified coins")
- Build provable scarcity tech (show me cache hit rates, not vanity metrics)
- Become the PCGS of your vertical - the trusted authority
The New Scarcity Calculus
That ugly VG8 coin outperforming pristine specimens? It's not luck. It's a lesson for founders: value accrues to those who solve hard problems in overlooked corners. The next unicorns won't chase crowded markets - they'll build technical moats around scarcity others can't replicate. And when they do? That's when we start talking 10x returns.
