Why are SaaS revenue multiples collapsing in the AI era?

THE SHORT ANSWER

There are two repricings happening at once, and confusing them is dangerous. One is AI destroying the option on moats denominated in accumulated human effort or content: Airtable sold at about 2.7x ARR, Chegg lost roughly 99% of its value as ChatGPT and Google AI Overviews ate its answer library, and Prosus wrote Stack Overflow down from $1.8 billion toward $564 million as question volume fell more than three quarters. The other is zero-interest-rate growth assets repricing to cash-flow multiples through private-equity buyouts: Squarespace at $7.2 billion and Smartsheet at $8.4 billion. You wait out a rate repricing. You cannot wait out an AI repricing, because the value of the moat itself fell. Ask what your moat is denominated in to know which one you face.

One company is an anecdote. The repricing thesis needs comparables, and once you line them up they split into two different curves that are easy to confuse.

The two curves

The severe curve is AI destroying the option on effort-and-content moats. Airtable sold at roughly 2.7x ARR because its moat was the effort customers spent modeling workflows, and effort deflates as agents make effort cheap. Chegg lost about 99% of its 2021 value because ChatGPT and Google AI Overviews reproduced its decade of curated homework answers. Prosus wrote Stack Overflow down from a $1.8 billion purchase toward roughly $564 million as AI coding tools cut its question volume by more than three quarters. Same mechanism three times: a moat made of accumulated human labor, regenerated cheaply by a model.

The survivable curve is rate-driven. Squarespace went private at about $7.2 billion and Smartsheet at $8.4 billion, both healthy growing businesses repriced from a growth-story premium down to a cash-flow multiple as money got expensive and private equity became the most rational owner. Six to eight times revenue is not a collapse. It is what a solid software business is worth without the story premium.

Why telling them apart is the whole skill

You survive a rate repricing by waiting. You cannot wait out an AI repricing, because time does not restore a moat, it erodes it. From inside a company, early, the two look identical: multiple down, revenue still growing, cash still coming. A team that reads an AI repricing as a rate cycle will burn its runway waiting for a recovery that structurally cannot arrive. The test is one question: what is your moat denominated in? Split your value into the option (AI-exposed) and the cash flow (rate-exposed), and price each honestly before the market does it for you.
