Pinsent Masons launches new tool to transform legal due diligence reporting

08 Sep 2025 | 08:14 am | 1 min. read

Multinational law firm Pinsent Masons has launched a new online platform to radically streamline the legal due diligence reporting process during complex M&A transactions.

The solution, named Portana, allows clients to immediately see where the key issues lie throughout the lifecycle of a due diligence exercise without having to review an extensive report. Portana also allows Pinsent Masons lawyers and clients to collaborate in real-time.

Pinsent Masons’ research and development team worked with clients to design Portana, consulting on the optimum functionality and testing the solution during several important M&A transactions across the firm’s key sectors.

The team also used secondees from Pinsent Masons’ corporate and commercial practices to work with the research and development team to ensure clients’ needs were at the heart of the design process.

Portana’s dashboard allows clients to instantly review the status of a due diligence exercise, providing:

• Key findings: A concise overview of critical areas.

• Detailed analysis: A clear outline of identified issues in a red flag style.

• Summary of investigations: A Q&A table that clearly outlines what has been considered and where the issues lie.

The solution shows clients the issues they need to prioritise to deliver the transaction, with the insights easily sorted by area of law, issue or suggested remedy.

Amie Norris, corporate partner at Pinsent Masons, commented, “Portana is the next step in the evolution of due diligence delivery at Pinsent Masons. Designed in collaboration with clients, it’s a dynamic, data-driven solution which brings due diligence reporting into the 21st century.”

James Kaye, fellow corporate partner, added, “We’re very pleased to have developed a technology solution which is grounded in client feedback and focused on client requirements. Our secondment process further reinforced that client-centric approach, ensuring that those that deliver our due diligence services were at the heart of the solution’s development.”
