Can AI Replace M&A Advisors? We Asked ChatGPT

Thursday, 27 March 2025

With all the buzz around artificial intelligence, particularly tools like ChatGPT, it’s no surprise that professionals across industries such as copywriting, law, and education are questioning whether AI could eventually replace human expertise. Naturally, as a corporate finance advisory in London, we were curious too.

Could AI really handle the complexity of UK mid market M&A? Could it support founders looking to sell a business in the UK, advise on valuation, or identify the right buyers?

So, we decided to put it to the test.

Valuing a Business: Where AI Falls Short

We started with business valuation. One of the most common questions founders ask when beginning business exit planning in the UK. When provided with basic financials such as revenue and EBITDA, ChatGPT did what many people do early on: applied a broad range of multiples, typically between 5x and 15x.

That approach can be helpful at a very high level. But in mid market corporate finance advisory, valuation is never that simple. AI struggled to assess qualitative factors such as growth trajectory, sector dynamics, competitive positioning, customer concentration, or management strength; elements that materially influence value.

Its default conclusion? “You should consult an appropriate advisor.”
On that point, we agree entirely.

Finding Buyers: Lists vs Relationships

Next, we asked ChatGPT to identify potential buyers. It confidently named large, well-known organisations such as WPP, Deloitte Digital, and Bain—firms any founder could identify with a quick search.

But effective business sale advisory in London is about far more than naming obvious players. In the UK mid market, successful outcomes depend on building a tailored buyer universe that reflects strategic fit, acquisition appetite, funding structure, and cultural alignment.

For niche sectors, whether SEO, martech, SaaS, or specialist services, finding the right acquirer requires insight, discretion, and relationships that AI simply doesn’t have.

Deal Data, Due Diligence, and Real-World Limitations

When asked about recent transaction data or precedent deals, ChatGPT acknowledged its limitations. Much of the information that underpins effective mid market M&A advisory in London is confidential and proprietary.

Its recommendation? Engage a research firm or search online.

That’s precisely why founders working with M&A advisors for business owners gain an advantage: access to real-world deal experience, current market intelligence, and buyer feedback that never appears in public databases.

Strategy and Integration: High-Level vs Hands-On

On broader questions such as private equity trends, post-merger integration, or deal structuring, ChatGPT offered sensible but generic frameworks. Useful for understanding concepts, perhaps, but a long way from the tailored, deal-specific advice required when selling a private company in the UK.

M&A is as much about judgement, timing, and negotiation as it is about theory. These are areas where experience matters: and where AI remains limited.

So, Can AI Replace M&A Advisors?

In short: no.

ChatGPT is a useful educational tool. For founders new to M&A, it can explain concepts clearly and quickly. But when it comes to the real work—preparing a business for sale, positioning it correctly, managing negotiations, and navigating the human dynamics of a transaction, there is no substitute for experienced advice.

That’s why businesses continue to rely on corporate finance advisors in London, particularly in complex UK mid market M&A transactions.
