Key Quotes

The threat isn’t just from competitors building better versions of your product. It’s from your customers deciding they’d rather spend 20 hours building something specific than $20,000 a year on something general.

That’s the thing about AI eating software: it doesn’t always announce itself. Sometimes it just quietly removes you from a deal you never knew you were in.

  • Existing Customer Success platforms are outdated and lack meaningful AI integration, making them unsuitable for niche use cases.
  • AI is cutting into SaaS revenues by enabling customers to build niche-specific tools instead of buying horizontal platforms.

  • Two vendors lost approximately $20,000 each in ARR because SaaStr built their own solutions instead of buying.
