The build-vs-buy math just flipped

We needed sales software. Call a client, bridge the call to a rep, record it, transcribe it, feed it into our AI ops and SOPs. Nothing exotic. Plenty of tools do this off the shelf. We looked at it and asked why we'd buy it instead of building it. We're software developers. We build automations for clients every week. So we built our own. It was live in production in a couple of days. Now we own it outright. We can grow it exactly how we want, add the features we actually need, and it doesn't cost more as the team grows. An off-the-shelf tool's price climbs with every seat you add. Ours doesn't. Three to five years ago, this wasn't realistic. Custom software took real time and real money, so buying was almost always the smarter move. AI-assisted development changed that math. The build option is now fast enough and cheap enough to compete directly with buying, for problems that used to only make sense to solve with a subscription. That doesn't mean build everything yourself. It means the decision is a real decision now, not a foregone conclusion. Off-the-shelf still wins plenty of times. But "build it ourselves" is a legitimate option on the table in a way it just wasn't before.
