The Build vs Buy Math Just Flipped For thirty years a software renewal was a simple question of renew or shop for a cheaper seat, because building the thing yourself was never realistic. That has changed. Gartner now puts roughly a fifth of enterprise SaaS spend, around $234B, at risk of being done a different way by 2030. The reason is that the cost of building the workflows a company actually needs can now be done with tools like Software Factory. Keep renting commodity systems, and your business will perform like a commodity. Building software around the processes that are unique to how your business runs is worth pricing out before you sign another three-year contract for some off the shelf tool that will only ever approximate it.
