Permira's analysis suggests AI can replicate software features, eroding the value of high switching costs and recurring revenue. The new moat is whether a company owns critical data or is deeply embedded in workflows.

Users can now prompt an AI to build a custom version of a SaaS tool, tailored to their exact needs. This marks a shift towards personal, disposable software, which increases software's abundance while simultaneously eroding the moats of traditional SaaS businesses.

The rise of agentic coding is creating a "SaaSpocalypse." These agents can migrate data, learn different workflows, and handle integrations, which undermines the core moats of SaaS companies: data switching costs, workflow lock-in, and integration complexity. This makes the high gross margins of SaaS businesses a prime target for disruption.

Frustration with a mediocre, AI-lacking vendor drove the decision to build a custom replacement, even when a commercial option existed. This signals a major vulnerability for incumbent SaaS players who fail to innovate with AI, as customers may choose to build rather than renew.

Enterprise sales for SaaS companies are becoming harder because AI has dramatically lowered the cost and time required for customers to build solutions in-house. This gives customers a credible alternative during renewal negotiations, eroding the vendor's pricing power and leverage.

Enterprises no longer need to buy expensive SaaS products for tasks like customer feedback. They can now spin up custom AI agents internally, making it harder for SaaS companies to acquire new customers and leading to higher-than-modeled churn. This poses a fundamental threat to the SaaS business model.

AI coding agents will make migrating between complex enterprise systems like SAP and Oracle dramatically easier and cheaper. This erodes the moat of high switching costs, forcing incumbents to compete on product value rather than customer lock-in, where they once held customers as "hostages."

The ability for customers to build their own software features using AI agents directly threatens the traditional SaaS upsell model. During negotiations, customers can now credibly threaten to "roll their own" features instead of paying for higher-priced tiers, weakening the vendor's pricing power.

SaaS growth relies on upselling features and adding seats. AI challenges this by enabling customers to build their own integrations that were once expensive upsells. Furthermore, if AI keeps team sizes static, the "expand" motion of selling more seats vanishes.
