MANCHESTER, England–(BUSINESS WIRE)–Landsec, one of the largest commercial property development and investment companies in Europe, has selected corporate performance management (CPM) vendor OneStream, and OneStream implementation partner Black Diamond Advisory, to modernise budgeting, planning and consolidation across their enterprise, replacing MRI, IBM Cognos and Excel spreadsheets with OneStream’s Intelligent Finance platform.

Landsec manages some of the most successful and memorable places in the UK, with a £12 billion portfolio that spans 24 million sq. ft. of well-connected retail, leisure, workspace and residential hubs. As Landsec continues to grow, the company needed a CPM platform that could meet their long-term growth ambitions. Following a competitive evaluation process, Landsec ultimately selected OneStream as the best platform that could deliver their requirements today – as well as scale and support future growth.

“As we mapped out Landsec’s growth strategy, OneStream proved to be the best partner to streamline and unify our financial and operational planning processes across our business,” said Cassani Mairs, Finance Transformation Director at Landsec. “OneStream’s Intelligent Finance platform will allow us to remain agile as we continue our strategic expansion through data-driven insights and dynamic decision making.”

“We are honored to partner with Landsec to streamline their financial processes and provide the transparency and agility to address their most pressing business problems today, with the scalability to strategically grow with the organization,” said Johan Edlund, Senior Vice President of Sales EMEA at OneStream. “By digitally transforming Landsec’s financial processes, users will have the flexibility and insight to drive better, faster and more strategic decision-making across the enterprise.”

“From the initial discovery call, it was evident that the Landsec project objectives aligned perfectly with our OneStream experience and capability. The strength of the Landsec Leadership throughout the decision process truly demonstrated the company’s commitment to the partnerships they build and the sustainable places they create to connect communities,” said Randy Werder, CEO of Black Diamond Advisory.
