Big firms hit the brakes on AI

A year of enterprise AI cheerleading meets a stubborn datapoint: adoption at large U.S. companies just fell. The Census Bureau’s biweekly business survey shows usage among firms with 250+ employees dipping from roughly 14% in June to under 12% by August—the sharpest slide since tracking began in 2023. At the same time, an MIT study argues that 95% of integrated AI pilots deliver no measurable P&L impact.

What’s actually new

This isn’t a pause in growth. It’s a reversal. The government’s survey had recorded steady climbs since late 2023; now the biggest firms are rolling back live use. Smaller employers ticked up slightly, and mid-sized companies were flat to down, but the headline is clear: enterprise scale is where momentum broke.

MIT’s “State of AI in Business 2025” provides a plausible reason. Consumer-grade tools (ChatGPT, Copilot) are widely explored and even deployed, yet they lift individual productivity more than they move the P&L. Custom or vendor-sold enterprise systems rarely stick: only about 5% of task-specific pilots reach production, the report finds. The culprit isn’t model horsepower or regulation. It’s that most systems don’t learn, remember, or adapt to real workflows.

The evidence behind the cool-down

Inside companies, a “shadow AI economy” has flourished: employees use personal AI accounts at far higher rates than their employers buy official subscriptions. In MIT’s interviews, workers at over 90% of surveyed firms reported regular personal AI use, while only 40% of organizations had purchased an LLM subscription. Employees prefer general-purpose chat interfaces because they’re flexible, fast, and familiar. But those same tools are rarely trusted for mission-critical work. For complex projects, users choose humans by roughly nine to one. The dividing line is memory and adaptability, not headline “intelligence.”

The deployment math is unforgiving. Enterprises lead in pilot counts yet lag in scale-ups. By contrast, mid-market organizations that succeed move from pilot to rollout in about 90 days, often by partnering with vendors that customize deeply for a narrow workflow before expanding. In MIT’s sample, externally built solutions were about twice as likely to deploy as internal builds.

The money reality

Budgets reveal the same bias that’s now biting. Executives over-allocate to visible front-office bets—sales and marketing—because those wins are easier to attribute and present to boards. The higher, faster ROI often hides in back-office work: document automation, call routing, risk checks, and other routine processes that cut BPO spend and agency fees without splashy dashboards. Where projects do pay back, they do so as cost optimization, not net-new revenue. That’s a problem for an industry priced for growth.

What breaks—and how it gets fixed

Enterprises don’t need larger base models as much as systems that learn on the job. Today’s failures rhyme: brittle workflows that collapse at edge cases, tools that require full context every session, and UX that never improves with feedback. The fix looks less like another “assistant” and more like agentic, memory-capable software stitched directly into CRMs, ERPs, and ticketing systems. Frameworks for persistent memory and coordination—think Model Context Protocol and related agent-to-agent approaches—are early, but they target the right bottleneck: adaptation over time.

Winning buyers behave more like BPO customers than app shoppers. They decentralize discovery to frontline teams, insist on outcome-based benchmarks, and co-develop with vendors who commit to workflow depth, not just demos. Winning vendors land in narrow processes with low setup burden, prove value fast, then expand. The window to lock in those relationships may be short; once a system internalizes a company’s data and procedures, switching costs rise monthly.

Read this as maturation, not a panic

Biweekly survey data can wobble. MIT’s findings are preliminary and anonymized, drawn from 52 organizations, 300+ public implementations, and 153 executive surveys across a six-month research window. But the pattern across both is coherent: enterprises tried what was available, found it wanting for core work, and are now pruning. That’s not anti-AI. It’s procurement doing its job.

The hype can wait.

Limitations and caveats

The Census instrument captures short-window usage, not spend or intent, and can lag procurement. MIT’s study cautions about sample bias and varying success definitions by industry. Still, both point at the same friction: today’s tools don’t retain context or improve without heavy lift. That’s an architectural gap, not a mood.

Why this matters

• Valuations vs. value: If enterprise AI mainly cuts costs in narrow workflows, growth-stock pricing tied to top-line transformation needs a reset.
• Product direction: Memory, learning, and workflow integration—not bigger base models—are the features that move deployment and ROI.

Why 95% of Enterprise AI Projects Fail (And What Works)

Despite massive AI hype, 95% of enterprise projects deliver no real returns. The gap between promises and reality reveals hidden costs, workflow mismatches, and why human oversight remains surprisingly essential.
