Bridgepoint, one of the world’s leading quoted private asset growth investors, has announced it is partnering with NMi Group (“NMi”), a pan-European provider of independent Advisory, Testing, Inspection, Certification, and Calibration (“ATICC”) services.
The transaction sees Bridgepoint Development Capital V – a lower middle-market fund focused on supporting fast-growing businesses across Europe – become the majority shareholder in NMi, with the exit of existing partner Levine Leichtman Capital Partners (“LLCP”). NMi’s management team will reinvest alongside Bridgepoint, ushering in the next chapter of growth for the business.
Founded in 1873, NMi ensures the systems, devices, and services that shape our daily lives – such as electric vehicle (EV) charging infrastructure, smart meters, medical devices, mobile and payment technologies, industrial control systems and safety-critical instrumentation – are accurate, fully compliant and future-ready.
The company has built a leading platform designed to meet the mission-critical demands of clients bringing new and enhanced technologies to market, often in highly regulated environments – supporting clients across the UK, Europe, Asia and the Americas with market access services such as metrology, hazardous environment safety and cyber security certification. The business also provides a range of regulatory-driven in-life services to ensure products remain compliant and accurate throughout their use, including complex calibrations, verification services, and compliance assurance.
With c.300 employees across nine sites, NMi serves over 7,000 clients in high-stakes sectors such as energy and utilities, technology, manufacturing, defence, transport and life sciences. Growth in recent years has been strong, driven by a combination of organic momentum and a disciplined buy-and-build strategy – underpinned by a series of strategic acquisitions since 2020.
NMi operates in a large and expanding global market for market access and in-life services. Growth is fuelled by increasing product complexity, evolving regulations, and rising demand for high-trust, impartial assurance –particularly in cybersecurity, industrial battery energy storage systems (BESS), and connected infrastructure. Anticipated regulatory changes, such as the EU Cyber Resilience Act and ongoing investment in energy transition and smart technologies, are expected to further accelerate demand for NMi’s services.
Bridgepoint will support NMi in scaling its international platform through continued investment in high-growth certifications and adjacent capabilities. The focus will include geographic expansion into regions such as the DACH and Nordic countries, and the development of enhanced commercial infrastructure. With its proven track record of scaling technical services and certification businesses, Bridgepoint will support NMi’s ambition to become a global leader and trusted technical partner in sectors like Energy Transition, Smart Mobility, and Digital Infrastructure.
Bridgepoint has deep ATICC sector experience through investments in companies such as Element Materials Technology, LGC, and Fera Science. Its partnership with NMi builds on this legacy and reinforces Bridgepoint’s strategy of investing in knowledge-led, high-growth businesses, including prior investments in Achilles, Sinari, and Surikat.
Matt Legg, Partner at Bridgepoint, said:
“NMi is a rare and high-quality international ATICC platform with an outstanding reputation for quality and trust, underpinned by a unique heritage and highly technical team. The business offers a compelling combination of sector-leading organic growth with significant further potential for M&A as the acquirer of choice in its space. With rising regulation and complexity across end markets, NMi is well-positioned to become a global leader in market access and in-life compliance services—an ambition we look forward to supporting alongside its management team.”
Yvo Jansen, CEO of NMi Group, added:
“This partnership aligns our long-term strategy with stakeholder needs. Bridgepoint brings deep sector experience and international reach—key as we support clients navigating increasingly complex regulatory landscapes. I’d also like to thank LLCP, who helped us scale with focus and discipline. With that strong foundation, we’re ready for the next stage—with our clients and new partners.”
Joanne Spick, CFO, NMi Group, commented:
"As regulatory demands grow, our clients need more than compliance—they need confidence. That means reliable services, smarter systems, and partners who are thinking long-term. With Bridgepoint’s support, we’ll keep investing in capabilities that matter, helping clients stay ahead and scale with assurance."
