HW Fisher Acquires Media Marketing Compliance (MMC) to Expand Forensic Offering

London, 8 October 2025: HW Fisher, part of the Sumer Group, announces its acquisition of Media Marketing Compliance (MMC), an industry-leading firm enabling businesses to achieve financial transparency throughout their media and marketing supply chain.

The acquisition strengthens HW Fisher’s forensic and audit capabilities by integrating its established expertise in licensing and investigations with MMC’s specialist knowledge in auditing media and marketing agencies across the globe. Together, this creates a comprehensive service offering to help clients audit and protect significant marketing and advertising spend.

With more than 20 years’ experience across 110+ countries, MMC is a trusted partner to leading advertisers worldwide. The team provides specialist expertise to ensure transparency and accountability in marketing spend, independently auditing contracts, costs, and delivery to help businesses verify that budgets are used effectively and deliver real value.

With the global advertising industry valued at $1 trillion annually, the acquisition responds to increasing client demand for specialist media and marketing auditing capabilities, meeting the needs of the complex media and advertising landscape.

Stephen Broderick, Senior Director of MMC, says: "Joining HW Fisher and the Sumer Group represents an exciting opportunity to strengthen our position in the market and expand our capabilities. As part of a larger, established organisation, we can better support our clients drive for transparency in the advertising and marketing industry. The synergies between MMC’s expertise and HW Fisher's broader audit and royalty auditing capabilities create compelling opportunities for both existing and new clients."

Andrew Rich, Managing Partner at HW Fisher, says: "The acquisition of Media Marketing Compliance represents a natural extension of our service offering and demonstrates our commitment to meeting our clients' evolving needs. Stephen and his team bring unparalleled expertise of the media and advertising landscape, complementing our existing forensic audit, contract compliance and royalty auditing capabilities perfectly.

Marketing is among the largest areas of corporate spend, often ranking just behind wages and raw materials as a company’s third biggest expense. This scale highlights the clear need for independent, specialist oversight. We are excited to support Stephen and the team in their continued growth and look forward to the new opportunities this will create for our clients.”
