The value in enterprise SaaS offerings isn't just the application functionality but the IaaS substrate underneath. The vendor handles server operations, storage, scalability, backups, security, compliance, etc. It might be easier for companies to vibe code their own custom applications now but LLMs don't help nearly as much with keeping those applications running. Most companies are terrible at technical operations. I predict we'll see a new wave of IaaS startups that sell to those enterprise vibe coders and undercut the legacy SaaS vendors.
