ID5 delivers Adaptive Identity for omnichannel advertising. We provide intelligent, privacy-first identity infrastructure that turns fragmented signals into scalable and measurable identity solutions across devices and channels. Our technology is trusted across the digital advertising ecosystem, empowering publishers, platforms, and brands to connect with audiences effectively, responsibly, and at scale.
The Opportunity
ID5 is entering an important new phase. Following the acquisition of TrueData, we now operate across three entities in the UK and US with approximately 85 people in 15 countries. We sit at the intersection of digital identity, data protection, software and advertising regulation, so legal judgment is embedded in our products, partnerships and revenue model rather than sitting at the edge of the business.
This is ID5's senior-most legal role and a genuine executive seat. Reporting directly to the CEO & Co-Founder, you will set legal and enterprise-risk strategy, hold final legal sign-off and give the CEO, founders and board clear, decision-ready advice.



You will lead a capable in-house team and specialist outside counsel, while remaining close enough to the business to make commercially pragmatic decisions at speed.
Alongside day-to-day legal leadership, you will strengthen the corporate foundations behind ID5's next phase of growth: clear governance, well-managed entities, robust contracts and IP and data rights, and reliable information and decision‑making. You will also lead the legal work on strategic partnerships, corporate development and any transactions that arise.
What You'll Do
Enable revenue through better contracting. Own the commercial contract architecture across customer and partner agreements, product modules, order forms, DPAs and NDAs; improve templates, playbooks, delegation rules and tooling so routine deals move quickly without the top legal seat becoming a bottleneck.
Set ID5's legal and risk strategy. Act as the accountable lega
