It starts well before the deal closes and continues for months afterwards. RELX’s careful approach to integrating the companies it buys is a major success factor in delivering sustained growth.
Small, targeted acquisitions have long been a key element of RELX’s growth strategy: it typically buys around 10 businesses a year, spending £400m a year on average in the process. It then devotes huge effort to integrating these companies into its four divisions: LexisNexis Risk Solutions, its risk business; Elsevier, its medical and science arm; LexisNexis Legal & Professional, its legal business; and RX, the exhibition business.
In financial terms, RELX’s acquisitions are modest relative to the company’s size so the impact on the group if one does not work out as planned is minimal. But in the deals that RELX does, the risks are unusually asymmetric – the upside, when they go right, will be orders of magnitude bigger. For example, LexisNexis Legal & Professional attributes the improved answer quality and accelerated personalised AI features of its flagship AI legal assistant commercialised in August 2025 to the acquisition of Henchman, a Belgian legal technology company it acquired 13 months prior.
“The absolute priority for RELX is organic growth,” says Sybella Stanley, RELX’s director of corporate finance, who oversees the group’s acquisition pipeline. “That means acquisitions are always led by the strategic priorities of each division to deliver that organic growth – perhaps they need to supplement their products, or they can see an opportunity to accelerate their progress. Those are the reasons that we buy businesses.”

Enhancing existing offerings
It was Elsevier’s strategy to accelerate its transition from printed anatomy textbooks, notably Gray’s Anatomy, Netter’s and Sobotta, to digital products that underlay the acquisition of Dublin-based 3D4Medical in 2019. With medical schools phasing out the use of cadavers to teach anatomy, a high-quality digital offering was essential. Elsevier had been tracking 3D4Medical for several years, having been impressed by the preview of its Complete Anatomy product at an Apple event in 2015. The subscription-based business-to-business proposition positioned it firmly in the graduate medical education segment where Elsevier operated.
Elsevier had considered building digital anatomy products in-house, but gaining access to 3D4Medical’s developing Complete Anatomy product – already built with the aid of Elsevier’s content – put it on a fast-track to digitalise its anatomy offering. It could then expand rapidly into this space with several further products, including a world-first 3D full female anatomy model in 2021.
Niall Johnston, co-founder of 3D4Medical, says the integration process following the acquisition was gradual and involved minimum upheaval, enabling him to retain the talented creative staff who were critical to his plans. Elsevier also provided significant support early in the process to continue with product development, including the female anatomy model.
Six years on from the acquisition, Johnston, who is now part of Elsevier's global medical education leadership team, says, “I really liked the approach because it allowed people to settle into new processes, new systems, and at the same time keep the organisation structure and the role they had for a period. It’s not an exact science, but I thought the way they did it was very mature and effective.”
The combination of 3D4Medical’s expertise in digital content with Elsevier’s huge library of medical information quickly led to better products that serve a global market of medical students and professionals.
This is the pattern that underlies many of RELX’s deals. The right technology and product acquisitions enhance its existing offerings, creating new and better propositions that are hugely scalable, thanks to RELX’s global customer base and resources.
“Every acquisition starts from the point of saying: ‘If I bring this capability, this technology or this product into RELX and I combine it with what I own already, am I going to create additional value for customers, which will then give me accelerated organic growth over time? That’s the fundamental principle,” explains Stanley.
So even though the value of RELX’s deals individually might be modest, success hinges on getting the integration process right to make sure the value delivered to customers is significant. This, she says, is an “unwavering focus” across the group.

The due diligence test
People usually think of the integration process as something that gets under way once a deal has closed. But that is not the whole story: the seeds of a successful integration are sown much earlier than that.
In particular for RELX's small technology-driven acquisitions, the aim is to bring companies with innovative technologies and products into its “big tent” and ensure they find a close fit with their new teammates. For that to happen, the team working on the proposed acquisition must clear a couple of critical hurdles as early in the process as they can.
At the beginning of due diligence, explains Stanley, they will typically run a data test to assess the quality of the product they are interested in. Sometimes, as was the case with IDVerse, an Australian company that had developed cutting-edge technology to detect fake identity documents used in online transactions, a complementary capability has been identified via an existing commercial arrangement. Having successfully incorporated IDVerse’s technology into its fraud-prevention products for a period, RELX was able to establish the product’s quality and accuracy through further testing and bought the company in February 2025.
“We’d tested the capabilities of many businesses in this field by running our data through their solution and seeing how accurate the results were,” explains Stanley. “The one that came out absolutely the best and identified the things that were fake in the most accurate way was IDVerse. So we said, ‘That’s the one we want’.”
Alongside establishing the quality of the technology, RELX puts major effort into commercial due diligence – speaking to companies and customers that already use the technology to find out what they like about it, what could be better and how they view the joint products that an acquisition would enable. These steps provide the foundations of the acquisition plan, validating the quality of the technology and its potential to complement what RELX already owns, and incorporating feedback from users that provides a sense check on the acquisition team’s thinking.

Growing together
The gains made possible by achieving that shared vision are particularly well illustrated by the progress that Henchman and LexisNexis have made since their deal closed. Henchman had developed a tech solution that extracts and enriches the proprietary information that legal firms hold in their document management systems to enable faster drafting. It was obvious that adding trusted external content from LexisNexis would create a much more powerful proposition.
Months after the acquisition closed, LexisNexis launched Protégé, a personalised legal AI assistant powered by agentic AI capabilities, incorporating Henchman’s document management system technology. It allows users to combine their firm’s internal data with the full range of LexisNexis AI capabilities. RELX’s results for the first half of 2025 show revenue growth in legal had accelerated to 9 per cent, up from 7 per cent in the first half of 2024, as the legal business continued its successful growth trajectory.
To create the mutual understanding and alignment of ambitions that allows the combined team to move so fast requires careful planning and a clear understanding of the importance of people in every deal. In practical terms, that means that those from RELX who will work alongside the acquired company are involved in the due diligence process from the outset, so the team being acquired is always dealing with the people who will become their future colleagues. This continuity is important to building trust and showing people the kind of group they are joining.
RELX also has a well-rehearsed process for integrating back-office functions such as HR, legal, finance and payroll, which frees up time to focus on getting the technology, product and sales teams working smoothly together – and realising the growth opportunities that drove the acquisition to begin with.

culture proves decisive
High-quality companies always have choices. The founders of 3D4Medical, Henchman and IDVerse all considered other potential routes before deciding to go with RELX, and in some cases the discussions intensified when RELX learned they were looking seriously at other avenues. The factors that swayed their decision were based not only on a shared vision of what they could achieve with RELX, but also on what they learned about their acquirer and its culture during the due diligence process.
Both Opsomer at Henchman and Matthew Adams and Dan Aiello, co-founders of IDVerse, were impressed by how long the people they were dealing with had worked at RELX. “The tenure that you see with people in leadership positions and in general at LexisNexis is massive,” says Opsomer. “Even though it’s a huge company, everyone knows each other and knows where to get the right answer.” Johnston at Elsevier's 3D4Medical says the six years since the acquisition in 2019 “has provided a significant opportunity for talented people to get to another level professionally that we, as a small company, could not have offered them.”
From RELX’s perspective, Stanley stresses the importance of being transparent with founders during the deal discussions and “doing what you say you’re going to do”. Adams and Aiello at IDVerse say they were reassured on this score by the experience of ThreatMetrix, another Australian company that LexisNexis Risk Solutions had already bought. “Seeing how they kept the team intact and how they grew was a really good reference for us to see how they would treat us,” recalls Aiello.
Adams, meanwhile, says his impressions of RELX were borne out by the experience of meeting scores of senior colleagues in Barcelona at their first management gathering. “You realise that all these organisations that have been brought in share the same vision that you had as a founder and what you wanted to do for your business and your customers. There were so many of them around us. I genuinely did not expect that in such a large organisation."
“I think it’s down to their due diligence process – striving to make sure that the organisation that they’re bringing in really does fit the group as a whole and that the founders have the same objective as they do.”
