Online platform businesses face an environment of fast moving regulatory, market and commercial changes 

Platform businesses scale on code and data, not bricks and mortar. You move fast, iterate in real time and compete in markets and regulatory frameworks that never stand still. Your legal needs don't sit in neat boxes – you need advisers who understand how platforms create value and make decisions, working across legal disciplines simultaneously.

In just three years, the Digital Services Act (DSA), Online Safety Act (OSA), Artificial Intelligence Act (AI Act), Digital Markets Act (DMA) and Digital Markets, Competition and Consumers Act (DMCCA) have all passed, reshaping how regulators approach platforms. Meanwhile, laws governing data, cyber security, employment, product regulation and financial services continue to evolve across the UK, EU and beyond.

Competing here means balancing innovation against regulatory reality in real time. That changes what you need from external counsel: an embedded, multidisciplinary, cross-border partnership with lawyers who keep pace with your product cycles and move seamlessly from strategy to operational compliance. Osborne Clarke helps you get ahead of regulatory shifts rather than reacting to them, turning overlapping obligations into a clear plan that supports growth.

Why Osborne Clarke? 

Our experience acting for over 150 global platform businesses means we know first hand how you operate and make decisions. We give clear direction rather than cautious analysis, communicate the way you want us to and share our thinking in real time. Our advice reflects how a platform runs, not just what the law says, shaped by our many years of working with clients in this space.

We have extensive experience working with network effects, multi-sided markets, data and AI as core assets, rapid product cycles and changing commercial priorities. None of this is new to us, and we bring a depth of understanding to every piece of advice we give. 

Bringing together connected expertise across markets and disciplines

Platform issues rarely sit within a single jurisdiction or practice area. We bring together a combined UK and European team, spanning digital regulation, data, AI, competition, consumer, commercial, employment, disputes, IP, corporate, tax, financial services and more, coordinated so clients get one view of risk and one strategy.

Comply now, defend more easily later 

We've tracked regulatory regimes since before they were enacted, kept abreast of each consultation and scrutinised the relevant regulatory guidance. We know what compliance looks like to regulators and how to navigate the inevitable grey areas when applying this to a specific service. We are experts at complex regulatory implementation projects and have broad experience helping clients build a documented, defensible compliance position that aligns with their commercial realities. If regulators do come knocking, we leverage this understanding to provide strategic support on how to engage, defend and challenge as necessary.

Supporting the full life-cycle of online platforms

We support platform businesses across their full life‑cycle. Our teams advise on M&A, joint ventures, strategic partnerships and exits. We design and implement cross‑border workforce strategies and platform work models; protect the IP, data and technology that support your platform; and put in place commercial, licensing, marketplace and ecosystem agreements that are scalable, compliant and commercially robust. We also build the governance, documentation and evidence frameworks needed to operationalise regulatory requirements, and if disputes arise, we deliver rapid, coordinated responses that protect your operations, reputation and long‑term growth.

Who we work with and how we help

Osborne Clarke works with the full spectrum of online platforms connecting users, hosting content or facilitating transactions, regardless of their business models. Our clients include major social media platforms, providers of gaming ecosystems, video-sharing and messaging services, dating services, review platforms, people platforms and job boards, transport apps, fundraising platforms and online forums. We understand the distinct regulatory and commercial pressures each model brings.
