Guides for better software decisions.

Practical guidance on custom software, AI automation, integrations and product engineering, written from problems that appear while designing and operating real software rather than generic trend summaries.

17 published guides
Authority grounded in product work

We publish what we can explain and demonstrate.

PLAN0101 builds its own software as well as custom systems. CloserWin provides first-hand context in sales operations, integrations and automation; Clyvel in AI infrastructure, observability, cost and governance. Our guides turn those decisions into reusable frameworks.
