How Coin Authentication Mirrors M&A Tech Due Diligence: Spotting Red Flags in Code Quality

How Coin Collecting Taught Me to Spot Tech Red Flags in M&A Deals

When tech companies merge, there’s a hidden art to evaluating what you’re really buying. Let me show you why code quality assessments feel eerily similar to authenticating rare coins – and how both reveal truth through careful inspection. Like that time I examined an 1875 dime where the photos didn’t match reality, tech due diligence often begins with suspiciously perfect documentation that hides messy truths.

When Perfect Pictures Hide Flawed Systems

The coin world recently faced a crisis: experts couldn’t verify rare coins through manipulated images. Tech acquisitions face the same problem daily. Here’s what keeps me up at night:

• Architecture diagrams that look like modern art but hide tangled code
• Performance reports that ignore real-world stress tests
• Documentation that skips over the ugly parts (we all have them)

“Give me the commit history, not the press release,” my lead engineer always says. Just like coin experts demand unedited photos, we need raw access to repos and logs.

3 Code Authentication Techniques From the Coin Vault

1. The Date Stamp Test: Git History Forensics

Remember how specialists studied date fonts on questionable coins? We run similar checks on code timelines:

git log --since='2023-01-01' --until='2023-12-31' --pretty=format:'%h - %an, %ar : %s'

Last year, we found a company with 90% of commits squeezed into December. Turned out their “mature” platform was actually built in panic mode before acquisition talks.

2. The Mint Mark Check: Cloud Infrastructure Patterns

Authentic coins have precise mint marks. Real cloud setups show careful planning. We look for:

• Security groups left wide open like unlocked vaults
• Kubernetes clusters that resemble overgrown gardens
• Permission lists longer than a Dickens novel

One “secure” fintech startup had 82% of their data buckets exposed to the public internet. That’s like finding a Philadelphia mint mark on a San Francisco coin.

3. The Lettering Analysis: API Consistency Checks

Coin lettering reveals authentic dies. API contracts show engineering discipline. My team lives by this command:

swagger-cli validate api-spec.yaml

Broken endpoints and missing versioning are the crooked letters of integration risk. I once found an “enterprise-ready” API where 40% of endpoints didn’t match their docs.

Stress Testing: Beyond the Sales Pitch

Coin collectors weigh and measure. We crash-test systems. Here’s how:

Real-World Load Testing

Marketing claims melt under real traffic:

artillery run --target https://api.target-company.com load-test.yml

A “high-scale” platform we tested crumbled at 200 users – their claims? 50,000 concurrent. That’s like a coin failing the basic ring test.

Database Shard Inspections

We examine data partitions like coin reeding edges:

• Are shard keys creating hotspots?
• Can the system handle cross-shard transactions?
• Is there monitoring for partition skew?

Your Tech Due Diligence Toolkit

After 127 technical audits, here’s what actually matters:

Code Red Flags That Should Kill Deals

• Critical features with less than 60% test coverage
• High-severity vulnerabilities lurking in core modules
• Security checks missing from deployment pipelines

Green Lights Worth Paying For

• Automated rollback systems that work during dinner
• Real user monitoring catching issues before customers
• Machine learning predicting scaling needs accurately

The Art of Seeing Through the Shine

Authentic coins and solid tech stacks share something precious: they withstand scrutiny. That acquisition target resisting your engineers’ questions? That’s like a seller refusing to let you weigh their coin. Walk away.

True value welcomes inspection. Whether you’re holding a rare dime or evaluating a SaaS platform, remember: reality never needs Photoshop.
