Generally, for a bootstrapped business, the holy grain is a 90% margin.

This is even more true for AI-first businesses, since they operate with less costs compared to service businesses.

This obsession for margins is generally beneficial, but it has a limit. There are sometimes very good reasons to reduce a bit your margin.

One of these reasons is resilience.

If you operate a SaaS, you want to make sure to have a plan B if a provider fails. Investing in long-term resilience can feel like “suboptimal” from a margin perspective, but business is so unpredictable that it overall makes sense for critical providers (i.e. if they failed overnight you wouldn't have a functional service anymore).

To keep playing, you must survive, as they say.
