Most conversations about AI risk in business focus on the internal side — the cost of getting implementation wrong, the governance gaps, the ungoverned tooling your team is running without you. Those are real risks, and worth taking seriously. But Thomson Reuters' June 2026 Future of Professionals Report surfaces a different category of risk that tends to get less airtime: the client side. What happens when your clients have already decided what good AI-enabled service looks like — and you're not delivering it?
The report is based on a global survey of 1,816 professionals working in law, tax, audit, accounting, compliance, risk, and global trade, conducted in March and April 2026. It covers both the service providers and the corporate clients who hire them. The findings on the client side are not subtle. Seventy-eight percent of corporate clients now say AI-enabled quality improvements are essential in the firms they work with. Only 6% believe most of their providers are delivering those improvements. The math on that gap is straightforward: your clients have a clear expectation, and nearly all of them believe nearly all of their professional services providers are failing to meet it.
That 78-to-6 split is not a market research anomaly. It is the active state of client sentiment across every professional service category right now. The clients who use law firms, accounting firms, consultants, and advisors of all kinds have watched AI capabilities become normalized in consumer software over the past two years. They are running AI tools in their own businesses. They have a reasonably clear idea of what AI-enabled work should look like. And when they engage professional services, they are increasingly benchmarking what they receive against that standard — not against the legacy standard of what professional services have always delivered. Most providers are not meeting the new benchmark, and clients know it.
The $143 Billion Exit
The consequence of that gap is not a politely worded survey response. It is a procurement decision. Thomson Reuters found that 32% of corporate clients plan to reconsider their professional service provider relationships within the next 12 months, specifically as a result of AI-related underperformance. Among those considering a switch, a third say the relationships at risk represent more than $1 million in annual work each. The report's estimate for the U.S. market alone: $143 billion in client revenue that is actively in motion because providers have not closed the AI gap.
The reason this matters to founders — not just to the managing partners of large professional services firms — is that founder-led businesses sit on both sides of this dynamic. If you run a professional services or advisory firm of any kind, that $143 billion is distributed across your industry, and your own client relationships are part of the inventory. If you are a founder who uses professional services providers — lawyers, accountants, consultants, marketers, fractional executives — this is the context for evaluating whether the firms you pay are bringing you the leverage you are paying for.
What makes the Thomson Reuters numbers particularly credible is their specificity. This is not a survey asking whether AI is "important" to respondents — a question that almost universally produces high agreement because saying no sounds backward. It is a survey asking whether clients are prepared to take a specific commercial action: reassess a current provider relationship. Thirty-two percent saying yes to that question is a different and harder data point than 78% saying AI is essential. It is a signal about what is actually about to happen in the market, not what respondents believe in the abstract.
The Talent Side of the Same Equation
The client revenue story is the part of the Thomson Reuters report that tends to make headlines. But the findings on the talent side are equally significant, and in some ways more structural — because talent loss compounds in ways that client churn does not.
Among the 1,816 professionals surveyed, 91% reported experiencing some degree of what Thomson Reuters calls the "AI value gap" — the distance between what they expect AI to deliver in their professional environment and what it is actually delivering. Of those reporting a value gap, one in four (24%) said they were considering leaving their organization within two years. Thirteen percent said they were considering leaving within twelve months. Thomson Reuters estimates the replacement cost for a professional at $232,000 per person — accounting for recruitment, onboarding, and productivity loss during the ramp period.
The mechanism behind this is straightforward. Professionals who have learned to use AI tools effectively — and there are more of them every month — find that working in an organization that restricts, ignores, or fails to integrate AI limits their output, their learning, and their competitive development. They are less productive than they know they could be. They watch peers at more AI-mature firms advance faster. And they calculate, correctly, that their skills will atrophy more slowly at a firm that actually uses the tools.
For founders who run professional or knowledge-work businesses, this creates a compounding risk that is worse than client churn alone. Client churn can be reversed with better service delivery — win the client back, find a new one. Talent loss is slower to fix. The people most likely to leave for more AI-forward environments are exactly the people who have invested in learning to use AI well. The professionals who have not are the ones least likely to take the exit. That means underperforming on AI does not just cost you clients and people — it biases your team composition over time toward the members least equipped to close the gap. You lose the people most capable of solving the problem.
Why "We're Working on It" Is the Wrong Answer
The pattern Thomson Reuters identifies is not a story about firms that have ignored AI. It is a story about firms that have committed to AI at the strategy level without executing at the delivery level. Thirty-five percent of the professionals surveyed said their firm's AI ambitions are not reflected in their day-to-day work. Nearly one in five said their organization still lacks a clear AI strategy. The majority of firms in the sample are aware of the expectation, have made some form of public or internal commitment to AI, and are not delivering on it.
That is a very specific failure mode — and it is different from the one most coverage focuses on. The story is not "firms have not thought about AI." The story is "firms have thought about AI, announced AI initiatives, and then failed to translate those announcements into the workflow changes, tooling decisions, and training investments that would actually change how client work gets done." The gap between strategy and execution is where the $143 billion walks out the door.
This should land differently for founders than it does for enterprise executives. Large firms have layers of organizational complexity that make the strategy-to-execution gap genuinely hard to close. Founders have the opposite problem: they have the ability to move quickly, change how work gets done this week, and have a direct relationship with their team's tooling decisions. The gap that is costing enterprise firms clients and talent is, for a founder-led firm, entirely closeable in a short time window — if it gets treated as a strategy priority rather than an IT consideration.
The clients conducting their 12-month provider reviews are not primarily evaluating whether a firm has an AI policy on paper. They are evaluating whether the work product they receive reflects AI's actual capabilities — faster turnaround, more thorough analysis, better anticipation of second-order issues, deeper synthesis across more data than would have been practical to review manually. Those are outcomes, not announcements. The only way to achieve them is to actually change how work gets done, which means committing to specific workflow redesigns with specific tools and measuring whether the outputs improve.
What Closing the Gap Actually Looks Like
The Thomson Reuters report does not prescribe a specific implementation path, but the pattern in the data is clear enough to draw practical conclusions. The firms not at risk of losing the 32% are the ones whose AI ambitions are visible in day-to-day work — which means they have made specific decisions, not general commitments. Here is what those decisions look like in practice for a founder-led professional services firm.
Identify your highest-volume repeatable work product. Every professional services firm has work it does over and over — the research memo, the financial model, the contract review, the client report, the proposal. These are the workflows where AI has the clearest leverage because the output structure is consistent enough to build a reliable process around. Start with one. Not the most complex or the most visible — the one where you do the highest volume. Build a structured AI workflow for that specific work product, test it until the output quality is consistently better than what the manual process produced, then make it the standard way that work gets done.
Set a time benchmark for your most common deliverable. The single most credible signal a firm can give a client about its AI maturity is a faster turnaround without a quality drop. If the standard contract review takes five business days and AI lets you do it in two with equal or better accuracy, that is a direct and tangible client benefit. Pick one deliverable, set a benchmark for how long it currently takes, and build an AI-assisted process aimed at cutting that time in half. Measure the quality alongside the time. Once you have a demonstrable result, you have something to communicate to clients — not an announcement, a track record.
Make AI capability part of your hiring conversation, not a side note. Given that 24% of professionals are considering leaving firms that fall behind on AI, the AI capability question in hiring has flipped. Two years ago, asking a candidate about their AI skills was a nice-to-have. Now it is a signal to the candidate about what kind of firm they are joining. Asking "how do you currently use AI in your work" and "what workflows have you rebuilt around AI tools" tells you about the candidate and tells the candidate about you. Firms that are actively building AI-fluent teams signal that to the professionals who want to work in that environment.
Tell clients what you are doing, not what you are planning. The 6% delivery rate is partly a capabilities gap and partly a communication gap. Some of the firms at risk of losing clients in the next 12 months are actually doing more with AI than their clients know about. If you have rebuilt a workflow around AI, reduced turnaround time, or improved analysis depth, say so specifically — in a client communication, in a proposal, in a conversation during a review meeting. "We now review contracts using a structured AI analysis process that catches issues our previous manual review would miss" is a sentence that changes a client's benchmark. "We are committed to leveraging AI" is not.
The Thomson Reuters report is, in the end, a data-precise version of something that should already be obvious: clients are running their own AI tools, they have direct experience of what AI can do, and they are applying that experience when they evaluate what you deliver. The 78% who call AI-enabled quality improvements essential are not future clients — they are current clients, many of whom are reviewing their provider relationships this year.
The window between "you should be doing this" and "your clients are leaving because you didn't" is closing. The 32% reconsidering their relationships are not waiting for your strategy deck. They are watching your deliverables.
If you run a professional services or advisory business and are not sure where your AI delivery actually stands relative to client expectations, we can help you find out — and close the gap in the right order. Start a conversation. We'd rather tell you what needs fixing than let you lose the wrong client to a firm that moved faster. We'd rather tell you no than waste your money.
