Case Notes for SaaS builders

AI-first SaaS engineering from first principles.

Real product problems. Practical architecture. Zero-cost starts. AI-first scale. We investigate how modern SaaS systems are designed, built, measured, and grown.

First principles

Start with the real problem, actors, constraints, data, failure modes, and trade-offs before picking tools.

Zero-cost starts

Build lean first. Use free and low-cost infrastructure until the product earns its complexity.

AI-first scale

Add AI where it improves workflows, context, and decisions — with guardrails, auditability, and human control.
