A significant shift has occurred: private equity firms are no longer actively pursuing acquisitions of solid SaaS companies that fall short of IPO scale. This disappearance of a reliable exit path forces VCs and founders to find new strategies for liquidity and growth.

Investor Joe Lonsdale offers a heuristic for the 'SaaSpocalypse': low-end SaaS, particularly PE-backed companies that prioritized sales over deep tech, is in trouble. However, complex software that required over $100 million in engineering to build has a significant moat and is defensible against AI-driven disruption for the foreseeable future.

Contrary to the narrative that PE firms create leaner, more efficient companies, the data reveals a starkly different reality. The debt-loading and cost-cutting tactics inherent in the PE model dramatically increase a portfolio company's risk of failure.

For over a decade, SaaS products remained relatively unchanged, allowing PE firms to acquire them and profit from high NRR. AI destroys this model. The rate of product change is now unprecedented, meaning products can't be static, introducing a technology risk that PE models are not built for.

The ongoing decline in growth rates for public SaaS companies has created an existential crisis around revenue durability. Investors have lost confidence that traditional SaaS models can sustain growth in the face of AI disruption, leading to a massive valuation collapse.

In the age of AI, 10-15 year old SaaS companies face an existential crisis. To stay relevant, they must be willing to make radical changes to culture and product, even if it threatens existing revenue. The alternative is becoming a legacy player as nimbler startups capture the market.

For years, founders of profitable but slow-growing SaaS companies could rely on a private equity acquisition as a viable exit. That safety net is gone. PE firms are now just as wary of AI disruption and growth decay as VCs, leaving many 'pretty good' SaaS companies with no buyers.

Recent acquisitions of slow-growth public SaaS companies are not just value grabs but turnaround plays. Acquirers believe these companies' distribution can be revitalized by injecting AI-native products, creating a path back to high growth and higher multiples.

Established SaaS companies with strong, but not explosive, growth will struggle to raise new venture capital. Their path forward involves running a capital-efficient business while aggressively integrating AI to create new tailwinds, or else face a long, slow grind to a modest exit without further investment.
