Enterprise buyers are vibe-coding their way out of SaaS

A founder on r/SaaS shared a call with a 200-person agency whose CEO had launched an internal 'SaaS ditching program' after employees discovered they could vibe-code functional replacements for tools the company was paying for. The thread blew up because it named a fear that's been circling for months: not just that AI lowers the cost to build software, but that your own customers are now capable of building against you.

This connects directly to a separate r/startups thread asking whether founders should stop building '2010-era businesses' with 2026-era tools. The pattern here is that commoditization is no longer just a competitive threat from other startups. It now comes from inside the customer's own org. A 200-person agency is not a technical company, and they're still doing it.

The counterpoint raised in the thread is that most vibecoded internal tools are fragile and unmaintained. They break, they have no support, and they don't scale. But the damage is real in the short term: it gives a procurement veto that's hard to argue against when someone's already demoing a working alternative in the boardroom.
