BAY AREA CODE INTELLIGENCE
The Velocity Trap: What SF Engineering Teams Don't See Coming
Seed to Series B in 18 months. The codebase that made it possible? It's now your biggest liability. But not in the ways you'd expect.
What We See in Bay Area Codebases
After analyzing codebases from SF startups across seed to growth stages, patterns emerge that documentation never captures.
The "Temporary" Monolith
That MVP architecture from 2021? It's still there. But now it's handling 50x the traffic with 3x the features bolted on. The "microservices migration" has been on the roadmap for two years.
Seen in: 73% of Series A+ codebases we've analyzed
The Founder Code Problem
Early code written by technical founders who've since moved to exec roles. It works. It's critical. Nobody understands it. And there are no tests because "we were moving fast."
Seen in: 81% of codebases older than 3 years
The Dependency Iceberg
Front-end depends on a utility library that depends on a deprecated package that depends on something with a CVE. The surface looks fine. The iceberg is underneath.
Seen in: 94% of Node.js codebases
The Tribal Knowledge Exit
Your senior engineer who "knows where everything is" just got a 40% raise offer from a competitor. When they leave, six months of context walks out with them.
Risk factor: SF average tenure is 1.8 years
Why San Francisco Teams Hit This Wall
The Bay Area optimizes for speed. YC tells you to "launch and iterate." Investors want traction metrics. Your board asks about growth, not technical debt.
So you hire fast. Ship fast. Pivot fast. The codebase absorbs every decision, every shortcut, every "we'll fix this later." And later never comes—because there's always another feature, another quarter, another funding round.
The architecture that enabled your speed becomes the architecture that constrains it. That's not a bug in how startups work. It's the physics of technical debt compounding faster than you can pay it down.
From Our Analysis
Bay Area Codebase Patterns (2024-2025)
Based on LOOM analysis of 200+ codebases from Bay Area companies, 2024-2025.
When LOOM Isn't the Answer
We'd rather be honest than make a sale that doesn't fit.
Skip LOOM if...
- Your codebase is under 10,000 lines—grep is probably fine
- You have one developer who knows everything and isn't leaving
- You're in pure research/exploration phase with no production code
- Your architecture is genuinely documented and current (rare, but it happens)
LOOM shines when...
- New hires take months to become productive
- Changes break things in unexpected places
- Key developers are leaving (or you're worried they might)
- Nobody can answer "what depends on this?" confidently
Across the Bay Area
From SOMA startups to South Bay enterprises, code complexity doesn't respect zip codes.
SOMA / Mission
Seed to Series A. Moving fast, breaking things, accumulating debt. The codebase that got you here won't get you to scale.
South Bay
Enterprise scale, enterprise complexity. When your codebase spans dozens of repos and multiple teams, visibility becomes survival.
East Bay / Oakland
The emerging tech corridor. Smaller teams, tighter budgets, but the same architectural challenges as their SF counterparts.
