The Weekend Pitch
 
(Chloe Ladwig/PitchBook News)
For AI this year, the story has been one of relentless acceleration.

Startups have raced to launch market-changing products, enterprises have rushed to test them, and VCs have scrambled to fund them. Globally, the scale of AI investment hit $275 billion this year, according to PitchBook data, doubling the amount spent in 2024. Valuations and deal sizes have followed a similar trajectory.

For all the VC dollars pouring into AI, though, a weakness has emerged in the sector's financial underpinnings.

When examining fast-growing AI startups, annual recurring revenue has overtaken valuations as the go-to metric used to flaunt a company's expected yearly earnings.

Swedish vibe coding startup Lovable reached $100 million in ARR in just eight months, while app builder Emergent reportedly achieved $15 million in only 90 days. According to SaaS benchmarking platform ChartMogul, only one in 10 hit $10 million ARR, and AI-native startups are eight times more likely to reach that milestone within 12 months than the average SaaS business.

But this same metric is now raising eyebrows for the wrong reasons. Investors are growing increasingly concerned that ARR may be far less predictable than the market narrative suggests. As talk of a looming correction grows louder, the durability of that revenue base will influence the next phase of AI.

"The last two years have been wild," Marina Davidova, co-founder and managing partner at VC firm DVC, said. "We see some of the fastest-growing companies in history, but it’s never been harder for VCs to see through the noise of bloated numbers."

For decades, ARR has been a key metric that VCs depend on to gauge the financial health and growth potential of subscription-based startups. When a customer signs up for an annual plan, that revenue is recurring until the contract ends, allowing SaaS startups to forecast future cash generation with high accuracy.

At its simplest, ARR is calculated by multiplying monthly recurring revenue by 12. But that shorthand only works when a company's revenue is stable and genuinely recurring. In practice, not all revenue qualifies as ARR, and even within that ARR, the quality can vary depending on factors such as churn and contract terms. For AI startups, the financial outlook can become even muddier.

"For the majority of AI-native companies, ARR isn’t really ARR as we know it, but rather a hodgepodge of one-off, credits-based, performance-based or outcome-based revenue contracts," Mikael Johnsson, GP at VC firm Oxx, said. "This means that the predictability and stickiness for this revenue will be much worse than traditional subscription-based revenue."

Quote/Unquote

“Given the size and the amount of capital that Medline was able to raise today, I think it signals positive momentum on the private side. An IPO of this size demonstrates the resiliency of the market and the return of a margin of safety to the equity market."

Trivia

Answer: D

In today’s dollars, Facebook completed its IPO at a pre-money valuation of $91.9 billion, meaning it would take eight IPOs of that size to reach the same valuation that SpaceX could have in its IPO next year. See more figures about just how massive SpaceX's listing could be here.
