With a new agentic-lashup tearing across the internet every week, pointing the way to "gradient descent" software development, any purchasing manager worth their salt is going to ask some serious questions about their enormous SaaS bill before committing to another expensive long term contract. It follows that valuations must decline. Even if only because risks to moats have increased, but also because it makes sense to negotiate hard on pricing when there's fear in your counterparty.
Preposterous. Have you ever worked for a company as a programmer or for that matter as a manager? They don't just replace products ad hoc. There's an enormous amount of due diligence that goes into any new software product - making sure it fits the company, that it's secure, that it works properly... I recently worked at a small startup who spent on sales force @ $100,000 a year. I said you know what we could do this ourselves and you know what they said as every company I've ever said that to says? "We don't want to support it. We need to cover our ass. Everybody knows how to use this"
