Private equity investor LDC has made a significant investment in procurement and technology specialist The 55 Group to support its ambitious growth strategy.

The Hull-based group provides market-leading built environment-related software and services to public and private organisations across the UK.

The deal signifies an exit for Maven and represents the third successful exit for Maven’s Buyout Fund, following the realisations of John McGavigan in 2022 and Titan Wealth in 2023.

The 55 Group has grown rapidly in recent years following increased demand for digital solutions that support sustainable procurement practices and investment in critical UK infrastructure.

It employs more than 90 people and has grown revenue and headcount by over 35 per cent since 2022.

LDC is backing The 55 Group’s existing management team, led by co-founder and CEO Simon Toplass, as it pursues an ambitious growth strategy underpinned by further investment in its technology and services.

As part of the transaction, Maven, will retain a small shareholding in The 55 Group.

Simon Toplass, co-founder and CEO of The 55 Group said: “Our stable of brands are perfectly positioned to support organisations at every stage of the procurement and construction management process, making it easier for both buyers and suppliers of construction services to factor metrics like social value into decision making, which are essential if the entire ecosystem is going to continue to have a positive impact on communities.

Dan Smith, partner and head of Yorkshire at LDC, added: “The 55 Group is a great example of a fast growing Yorkshire business led by a hugely ambitious team.

“It represents LDC’s third investment in the region in just under 12 months, underlining our commitment to supporting the best businesses in Yorkshire.

“It is also another example of the strength of our leading software and data credentials in the built environment space, where we continue to see a shift towards more digital ways of working and an increased focus on ESG.”

Will Scales, investment director at LDC, added: “We are delighted that Simon and team have chosen LDC as their partner to support the delivery of The 55 Group’s next phase of growth.

“The quality of The 55 Group’s offering and technology in supporting sustainable and compliant practices is unique and we are excited about what the future holds for the business as it continues to invest in its people, products and services.”

LDC has a successful track record in the technology sector. Since 2012, the firm has invested over £650m into more than 35 fast growing technology businesses, backing management teams to achieve their ambitions.

LDC’s current portfolio includes a diverse range of technology businesses such as Uinsure, the cloud-based technology platform; The Building Cost Information Service (BCIS), the leading provider of cost and carbon data to the UK built environment; and Sedex, the market-leading sustainability data and technology provider.

The 55 Group was advised by Rothschild (Stephen Griffiths), Addleshaw Goddard (Richard Hunt and Peter Wood), Graph Strategy (James Tetherton) and KPMG FDD. Management were advised by Park Place (Richard Firth).

LDC was advised by KPMG (Ben Taylor), Squire Patton Boggs (Paul Mann and David Milne), DSW FDD (Jonathan Steed), PMSI (David Crout), Better Faster Growth and Catalysis.

HSBC, advised by DLA Piper, provided financing and working capital facilities to support the transaction.

The 55 Group’s offering comprises three brands including Pagabo, a procurement platform that connects private and public sector buyers to contractors via bespoke national frameworks, Loop, social value measurement software supporting the construction and infrastructure project lifecycle, and Sypro, a cutting-edge contract and risk management software solution for ongoing project management.
