Why Technical Diligence in Coin Valuation Is a VC’s Secret Weapon for Startup Investing

As a VC, I Look for Signals of Technical Excellence and Efficiency in a Startup’s DNA. Here’s My Analysis on Why a Team’s Approach to This Specific Issue Is a Powerful Indicator of Future Success and a Higher Valuation.

I spend most of my days listening to startup pitches. Revenue numbers. Market sizes. Team bios. They’re all important, but what really catches my attention? The founders who treat their tech like a rare coin collection—scrutinizing every detail, knowing exactly what’s real and what’s just shiny packaging.

The thread you shared about identifying valuable coins? That’s not just about numismatics. It’s my playbook for spotting startups worth backing. At seed funding and Series A stages, I look for founders who approach their tech with the same rigor as a coin expert does their collection. The parallels between coin authentication and grading and technical due diligence are striking. Founders who get this right don’t just raise money—they command higher valuations.

The Coin Grading Framework: A Blueprint for Technical Due Diligence

You hear “revolutionary AI platform” and think “big promise.” But is it real? Is it unique? Is it built to last? Just like with rare coins, appearance doesn’t equal value.

A coin might look special—a “doubled die,” “foreign planchet,” or “90% silver dime”—but until PCGS or NGC verifies it, it’s just a coin with a story. That CTO’s GitHub might look impressive with its flashy commits, but if the codebase isn’t clean, tested, and auditable, it’s just another pretty facade.

That’s why I use a grading framework inspired by coin experts:

1. Material Authenticity: What’s Really Under the Hood?

Coin experts test metal composition. I test tech composition:

• Is that “proprietary AI model” actually custom-built, or just fine-tuned open-source?
• Are those “exclusive APIs” truly yours, or just public services with a new wrapper?
• Is that “revolutionary database” a custom build, or a copy of what everyone else uses?

Here’s my litmus test: I ask for a technical composition report that shows every layer:

// Example: What I Need to See
{
  "core_architecture": {
    "database": "PostgreSQL 15 (self-hosted, optimized sharding)",
    "backend": "Python/FastAPI (custom ORM, async I/O)",
    "ml_model": "Custom transformer (trained on 50M proprietary user sessions)",
    "infra": "Kubernetes on GCP, autoscaling + spot instances"
  },
  "third_party": {
    "auth": "Auth0 (not self-built)",
    "analytics": "PostHog (self-hosted)"
  },
  "proprietary_components": [
    "User behavior prediction engine",
    "Real-time anomaly detection system"
  ]
}

This report is the tech version of testing a coin’s silver content. It separates real innovation from re-skinned solutions.

2. Error Analysis: Do They Fumble or Fix with Precision?

One person on that coin forum thought they had a rare “doubled die” error. Experts called it “mechanical doubling”—a common flaw worth zero extra. That’s exactly how I evaluate startup troubleshooting.

I want teams who diagnose with precision, not panic. I look for answers like:

• Instead of “our API is slow,” I want: “We found the latency came from N+1 queries. Fixed it with a denormalized cache layer.”
• Instead of “the AI model’s inaccurate,” I want: “We spotted data skew, balanced it with synthetic augmentation, and boosted F1 by 22%.”

My favorite question: “Show me your worst tech failure and how you fixed it.” I’m looking for three things:

• Did you find the real problem? (Not just the symptom)
• Where’s the proof? (Logs, metrics, A/B tests)
• Did you prevent it? (System fix, not quick patch)

Teams that treat tech like a science—not a magic trick—earn my trust.

When to Pay for the Audit (And When to DIY)

That coin collector wondered: “Are my coins worth grading?” The answer? Only if they could be valuable and you use a reputable service. Otherwise, $20-$100 per coin isn’t worth it.

Same goes for technical audits:

• Early on? Self-audit. Do code reviews, load tests, dependency scans yourself.
• Scaling? Invest in third-party audits (security, performance, scalability).
• Series A? Professional audit—like sending a coin to PCGS—is non-negotiable.

Real talk: A SaaS with 10,000 users and $100K ARR doesn’t need a full pentest. But at $2M ARR with enterprise clients? SOC 2 compliance isn’t optional. The cost-to-value ratio has to make sense.

3. Documentation: The Tech Stack’s Provenance

A graded coin in a sealed case (“slab”) gives buyers trust. Your startup’s tech needs the same:

• Code documentation = the slab. Is it clear and current?
• Architecture diagrams = the coin’s history. Do they show how the system evolved?
• Test coverage = the grading score. Is it 85%+ with integration tests?

I’ve passed on “hot” startups because their docs were “coming soon.” Well-documented tech reduces risk. And less perceived risk? That means higher valuation. AngelList found startups with >70% test coverage and good docs raised 23% more at Series A.

When Sentiment Masquerades as Value

One person inherited a “rare SMS quarter.” But without proof it was from a mint director’s set, it’s just a coin. This is the sentimental value trap: believing something’s valuable because of the story, not the substance.

I see this all the time:

• “Our algorithm’s special because our CTO worked at Google.” (Patent? Benchmark? Nope.)
• “We’re the only ones using WebAssembly.” (Performance data vs. alternatives? Missing.)

My challenge to founders: Prove it. I ask:

• Can you show this is better, faster, or cheaper than what’s out there?
• Where are the third-party benchmarks? Customer case studies? White papers?

Without evidence, it’s a coin in a case—not a graded asset.

Why This Changes the Valuation Game

At seed stage, I want teams who act like scientists. They don’t just build—they test, measure, verify. This lowers my risk, letting me offer better terms (higher valuation, lower equity ask).

At Series A, I need proof: audited code, third-party benchmarks, clear scalability. Startups who deliver this get 30-50% higher valuations than those with “cool tech” but no proof.

Just like a PCGS-graded coin trades at a premium, a technically validated startup demands a premium in the market.

My Due Diligence Checklist

Here’s what I look for—inspired by coin grading:

1. Material Authenticity: Prove your stack is what you say it is (show me the composition report).
2. Error Diagnosis: Can you find and fix real problems—not just symptoms?
3. Audit Readiness: Know when to DIY vs. hire experts (cost vs. value).
4. Documentation Quality: Treat your code and docs like a slab—clear, sealed, transferable.
5. Evidence Over Sentiment: Benchmarks, tests, and data beat personal stories.

Founders who nail this don’t just get funding. They set the valuation standard. When you treat your tech like a rare coin—with rigor, evidence, and transparency—you don’t just ask for a higher price. You earn it.
