Paris, April 22nd, 2025 - Didomi, a leading Global Data Privacy Solutions provider, is raising 72M€ with global private equity firm Marlin Equity Partners. This funding will be used to acquire server-side tagging platform Addingwell, fuel an ambitious organic and inorganic growth plan and set new standards for privacy-preserving data collection and activation.
Didomi co-founders, Romain Gauthier, Jawad Stouli, and Raphaël Boukris, are excited to embark on the next steps towards their vision:
The acquisition of Addingwell represents a significant milestone in our journey, reflecting a commitment to driving innovation and delivering enhanced value to our customers, at a time when companies need to adapt to a demanding privacy context with the right approach and partner for their personal data strategy.
This acquisition will consolidate Didomi’s position as a disruptive and ambitious force within the Data Privacy and Consent Management sector.
- Romain Gauthier, Co-Founder and Chief Executive Officer at Didomi.
Addingwell, led by co-founders Romain Baert and Julien Decroix, will join forces with Didomi, working together to deliver this shared vision to their existing client base as well as the industry at large:
We're thrilled to combine with Didomi. Our shared vision for innovation and commitment to customer success have always aligned, and we see meaningful expansion opportunities for our combined teams.
- Romain Baert, Chief Executive Officer at Addingwell
With this second acquisition (Didomi previously acquired a data privacy and compliance startup), Didomi furthers its message that data privacy is about more than compliance and has become a strategic, core business topic for leading organizations looking to enhance data sovereignty and data effectiveness.
Privacy-preserving data collection and activation
Amidst major changes in the digital ecosystem, including the growing regulatory patchwork of privacy law and the shift away from the reliance on third-party cookies, organizations are seeing the increased value of maintaining control over data collection throughout their users’ interaction with brands and devices.
Server-side tagging is emerging as a critical solution for organizations to regain control of their data operations while optimizing performance and ensuring compliance.
Server-side tagging is a no-brainer for any company serious about performance and data governance. It dramatically improves loading times, data quality, and user experience by reducing what runs in the browser.
But more importantly, it puts you back in control. You decide what data is collected, where it goes, and who can access it. In an era where trust and compliance are non-negotiable, that’s not just a technical upgrade — it’s a strategic one.
- Julien Decroix, Co-Founder at Addingwell
Didomi brings a wealth of new solutions to help clients monitor and ensure data is consented before being collected and leveraged throughout the advertising and marketing stack.
We are very excited by the perspective of making monitoring, compliance, and security over any server-side tagging setup simple and effective to deliver the performance benefits that come with this architecture.
- Jawad Stouli, Co-Founder and Chief Technology Officer at Didomi
Moving consent and data collection from a third-party to a first-party basis will bring Didomi clients clear and measurable benefits in terms of performance, data quality, and governance. Didomi's product research and development confirms the advantages for privacy-preserving solutions across the 35 countries in which it operates.
A fast-growing, major player in France, Addingwell supports over 2,000 clients in their server-side tagging implementation, optimizing their data strategies to maximize marketing and advertising ROI in a compliant manner.
Addingwell's ability to allow IT teams to securely delegate elements of implementation to data, legal, and marketing teams is part of what makes it such an effective solution. Their comprehensive tag and data monitoring allow companies to maintain control over their data collection and sharing flows.
Addingwell has done an exceptional job over the last few years, growing into a reference for companies looking to adopt server-side tagging. We are excited to join forces with them and help scale their solutions internationally.
- Raphaël Boukris, Co-Founder and Chief Revenue Officer at Didomi
This transition, led by two EU privacy technology leaders, comes at an ideal time to address growing challenges. With the transatlantic Data Privacy Framework between the EU and the U.S. facing potential hurdles, European-built solutions can be well-positioned to ensure long-term data control and compliance.
Welcoming a new partner to fuel an ambitious international growth plan
The acquisition of Addingwell comes with a new addition to the Didomi team: Marlin Equity Partners, a global investment firm with offices in London and Los Angeles, approximately $10 billion in capital commitments, and over 260 acquisitions under its belt.
Didomi and Addingwell’s innovative products and talented leadership teams have established them as market visionaries in their categories. We are excited to partner with them at this decisive moment in their growth trajectory and look forward to leveraging Marlin’s network and operational resources to take the group to the next level of success, combining aggressive organic expansion with other potential acquisitions.
- Jeremy Nakache, a managing director at Marlin Equity Partners
Marlin Equity Partners brings expertise in supporting companies in their expansion into new geographical regions, technologies, and market segments. The firm’s primary goal is to support organic growth acceleration and long-term value creation in the companies it partners with.
This strategic partnership and the acquisition of Addingwell mark a significant step in advancing Didomi's vision: preserving privacy at every step of the data journey while supporting global enterprises with their data collection and activation needs. The company envisions more additions to its solution portfolio for organizations looking to explore further how personal data can deliver value, with or beyond consent:
For the past years, privacy has been almost exclusively associated with a regulatory compliance exercise. Companies have too often forgotten about its impact on user experience and business outcomes. Didomi is here to help companies gain back control over the way privacy is affecting the value of personal data at the source, when it’s collected, and in transit, when it’s shared.
We believe this is the sort of privacy program companies need, and we are committed to delivering the best solutions globally to support that thesis.
- Romain Gauthier, Co-Founder and Chief Executive Officer at Didomi
