The SaaS ecosystem is no longer a buffet — it is a supply chain. Every tool you pick is a node that other tools depend on. The wrong pick costs you for years.
Choose for Integrations, Not Features
A "best-in-class" tool with a closed API is worse than a B-tier tool that talks to everything. Optimize for connectivity first, polish second.
Plan for Migration on Day One
Build with the assumption that you will replace any single tool within three years. Keep your data exportable, your IDs portable, and your workflows tool-agnostic where possible.
Lean on Specialists
Pick partners who live inside the ecosystem you operate in. They will save you years of trial and error — and most of their value is in what they tell you not to use.
