Dissecting SaaS Risk in the Age of AI

SaaS companies are down 27% YTD, while the S&P 500 is roughly flat. The sector has become an increasing source of concern for investors. What we are witnessing is a transition into a new phase of the SaaS lifecycle. This sell-off marks the end of the halo period that long insulated SaaS from conventional competitive scrutiny. For more than a decade, capital flowed freely into software companies with little concern about existential risk. The business model appeared unusually insulated: long growth runways, recurring revenue, high gross margins, and high switching costs. This combination created ideal conditions for structural overvaluation. Our contention is that, for much of the time these companies have been public, they were overvalued because markets priced their economics as both durable and permanent.

AI Eats SaaS?

This was originally intended to be a write-up on Zoom, as we believed the company held a strong strategic advantage in its core video communications franchise. Initially, we thought Zoom could leverage this position AI to expand its role within the enterprise. However, the lack of meaningful innovation to date, combined with increasing competitive pressure from Microsoft Teams, has led us to adopt a more neutral view. While we believe Zoom may experience modest growth going forward, we see the business as fundamentally growth-constrained, facing an expanding set of competitive threats and limited pricing power.

Bubbles, Bottlenecks, and Blackwells

This piece is a state of play for investors. We summarize the current moment: the scale of capital being deployed, where real bottlenecks exist, how system-level advances like Blackwell are shifting constraints, how unit economics are evolving, and why enterprise adoption still lags consumer use. The aim is to give investors a coherent snapshot of where AI stands today, what is driving returns, and what factors will determine where value accrues next. A quick aside on valuations: At its peak AOL had a market cap of $220B with 25mm subs valuing each sub at $10k as everyone thought they would be the gateway to the internet. Giving Open AI the same value, it would be at a $10T valuation, it is about 1/20th of that.
