40i Lab
Product experiments for real problems.
I ship small SaaS tools, test them in public, and keep only what proves useful.

How this lab works
Find a narrow pain
I pick one sharp problem, not a broad platform.
Ship a focused tool
Production-grade, minimal UI, measurable outcomes.
Measure honestly
Iterate, pause, or archive. No zombie products.
Why this exists
Most products are built behind closed doors.
I prefer to ship in the open, measure what works, and share what I learn.
