The venture capital benchmark for elite growth has shifted for AI companies. The old "T2D3" (Triple, Triple, Double, Double, Double) heuristic for SaaS is no longer the gold standard. Investors now consider achieving $100M ARR in under three years as the strongest signal of exceptional product-market fit in AI.

In the current AI boom, companies are raising subsequent funding rounds at the same high revenue multiples as previous ones, months apart. This is because growth rates aren't decelerating as expected, challenging the wisdom that valuation multiples must compress as revenue scales.

Perplexity, reportedly valued at $20B, is paying Snap—valued at half that—$400M for distribution. This inverted dynamic, where the less mature company pays for access, highlights how AI-related market caps are often detached from fundamental business performance like revenue and user base.

The startup landscape now operates under two different sets of rules. Non-AI companies face intense scrutiny on traditional business fundamentals like profitability. In contrast, AI companies exist in a parallel reality of 'irrational exuberance,' where compelling narratives justify sky-high valuations.

For a proven, hyper-growth AI company, traditional business risks (market, operational, tech) are minimal. The sole risk for a late-stage investor is overpaying for several years of future growth that may decelerate faster than anticipated.

The burn multiple, a classic SaaS efficiency metric, is losing its reliability. Its underlying assumptions (stable margins, low churn, no CapEx) don't hold for today's fast-growing AI companies, which have variable token costs and massive capital expenditures, potentially hiding major business risks.

AI-native companies grow so rapidly that their cost to acquire an incremental dollar of ARR is four times lower than traditional SaaS at the $100M scale. This superior burn multiple makes them more attractive to VCs, even with higher operational costs from tokens.

Contrary to common belief, the earliest AI startups often command higher relative valuations than established growth-stage AI companies, whose revenue multiples are becoming more rational and comparable to public market comps.

The CEO of Numeral notes that in the current fundraising climate, startups must heavily feature AI in their pitch to secure investor meetings. Furthermore, landing a major AI lab as a customer has become a key signal for VCs, leading to valuation multiples as high as 100-200x revenue for some companies.
