Key Takeaways

  • SaaS platforms must build features that work adequately for thousands of customers (breadth).
  • Custom infrastructure builds features that work perfectly for one customer (depth).
  • Enterprise software enforces generic data models; custom infrastructure matches your business reality.

Enterprise software platforms are built for thousands of companies. Custom infrastructure is built for one company. This isn't better or worse. It's a fundamental architectural trade-off.

The Multi-Tenant Constraint

SaaS platforms face a core constraint: they need to serve thousands of customers profitably from shared infrastructure. This forces specific architectural decisions: Features for Everyone, Generic Data Models, and Shallow Integrations.

The Single-Tenant Approach

At 42 & Company, we build infrastructure for specific businesses, not for everyone. We can build features that perfectly fit specific workflows, even if they'd be confusing for other businesses. We build database schemas that capture specific business relationships, not generic templates.

"The real question is: does my competitive advantage come from having infrastructure that works adequately like everyone else's, or infrastructure built specifically for my business?"
