https://andres.co/writing/ Notes on building with judgment: how I measure it, why it matters, and what holds up under scrutiny. en Tue, 30 Jun 2026 12:00:00 GMT https://andres.co/writing/build-vs-buy-after-building-got-cheap/ https://andres.co/writing/build-vs-buy-after-building-got-cheap/ Tue, 30 Jun 2026 12:00:00 GMT In 2020 I argued that unless software is your technological base, you should buy SaaS, not build. The framework was right and still is. The reason behind the advice is what AI inverted: the cost of building collapsed, and with it the safe default. Build vs buy stopped being a cost question and became a judgment one: what deserves to be owned now that owning is cheap? https://andres.co/writing/building-is-cheap/ https://andres.co/writing/building-is-cheap/ Tue, 30 Jun 2026 12:00:00 GMT AI made building fast and cheap, which makes 'we shipped fast' a useless claim, because fast is meaningless without how hard. So I measure build velocity and software complexity straight from the git history, with a rubric anyone can reproduce. The result: a platform that took roughly 19,766 hours the old way now reaches the same complexity in about 168. https://andres.co/writing/saas-vs-inhouse-2020/ https://andres.co/writing/saas-vs-inhouse-2020/ Fri, 01 May 2020 12:00:00 GMT A 2020 piece on a question most companies get wrong: is software your technological base, or just a tool that supports it? The framework still holds. The default answer it reaches, buy SaaS instead of building, is the one AI later inverted.
