AI has ushered in a never-before-seen disruption in enterprise buying patterns. Companies are on pace to spend $4.25 trillion on technology in 2026, driven almost entirely by AI, according to IDC. New research from venture capital firm Madrona shows 74% of 150 enterprise IT professionals surveyed plan to expand their AI budgets in the next 12 months, while the rest plan to hold steady.
Yet these same enterprises say fewer than half of their AI pilots ever make it into full production — actually an improvement over MIT's infamous finding last year that 95% of enterprise AI projects had failed on ROI.
The most striking finding is that even when enterprises do adopt AI products, they don't commit long-term. Some 77% re-evaluate their AI vendors every six months or on a rolling basis. "This creates a 'fast in, fast out' dynamic that is fundamentally different from traditional enterprise SaaS, where multi-year contracts provided a moat of inertia," Madrona writes. "In enterprise AI, switching costs are lower and the re-evaluation cadence is relentless."
This has profound implications for startup ARR — the annual recurring revenue metric that drives valuations. Enterprise trial budgets fueled the initial AI boom of 2025, and this year was supposed to see big customers settling in. Instead, enterprise revenue remains insecure even after products graduate from pilot to production.
Part of the problem is pricing. Research from Andreessen Horowitz surveyed 50 technical AI buyers and found more than half want fees tied to work produced or outcomes achieved, rather than token-based usage. When pricing revolves around reports processed, tickets closed, or leads generated, it becomes "economically valuable to both sides," write a16z partners Tugce Erten and Sarah Wang.
The result is a new era of enterprise experimentation. It opens doors to startups — enterprises are more willing to try new tech — but an enterprise contract no longer guarantees long-term revenue. The SaaS playbook of landing a big customer and riding inertia for years has been broken. Startups must now prove their worth continuously, every six months, through measurable outcomes rather than lock-in.
