What's driving the growth
Multiple research firms point to overlapping drivers: rapid enterprise adoption of AI coding assistants and automated testing tools, expanding agentic AI pilots (Deloitte's January 2026 analysis noted that roughly 50% of companies already using generative AI are expected to run agentic AI pilots or proofs of concept by 2027, up from about 25% in 2025), and a broader shift from experimental AI budgets to production-grade deployment. North America continues to lead by region, holding over a third of global AI market revenue share, per Grand View Research.
The trust gap worth watching
Growth in spend hasn't fully translated into growth in trust. One widely cited data point: only about 16% of organizations report having a formal strategy and roadmap for implementing AI agents, and confidence in fully autonomous AI agents has reportedly fallen — from roughly 43% in 2024 to 22% in 2025, according to industry surveys. That gap between investment and confidence is a meaningful signal for anyone selling AI services: the market is large and growing, but buyers remain cautious, which rewards agencies that lead with transparency and proof rather than hype.
What this means for agencies and buyers
For agencies: the addressable market is genuinely large and still expanding quickly, but so is buyer skepticism — differentiation now comes from verifiable outcomes, not category positioning. For buyers: comparison shopping matters more than it did two years ago, simply because the number of vendors claiming AI expertise has outpaced the number who can back it up. Reviewing verified agency performance by category — software development, digital marketing, mobile app development — remains one of the fastest ways to close that gap.
