    April 22, 2025

    Didomi, a global data privacy solutions provider, is raising $83 million with global private equity firm Marlin Equity Partners to accelerate its international expansion and position itself as the leading digital trust platform globally. This “VC-to-PE” funding will be used to acquire server-side tagging platform Addingwell, which will bolster privacy-preserving data collection for the software platform’s clients.

    The acquisition of Addingwell comes amidst changes in the digital ecosystem, including the growing regulatory framework of privacy law and the shift away from the reliance on third-party cookies, in which server-side tagging is emerging as a critical solution for organizations to regain control of their data operations while optimizing performance and ensuring compliance.

    Through a comprehensive software platform, Didomi enables large corporations to optimize the collection and activation of user data, monitor vendor and tracker activity, reduce compliance risk regarding global regulations, and engage their users with personalized, privacy-first experiences.

    Marlin Equity Partners is a global investment firm with offices in London and Los Angeles, with approximately $10 billion in capital commitments.

    Addingwell is a software company seeking to build the next generation of server-side tracking infrastructure through its SaaS platform that enables marketers and data teams to collect accurate, privacy-compliant data by moving tracking away from browsers.

    The S&C team advising Didomi on corporate matters includes Arnaud Berdou and Céline Icardi. Alexis Madec and Michael Orchowski are advising on tax matters.
