About

Over the past five years, we have worked with 50+ technology and AI companies, including long-term engagements with globally recognised brands.

Our clients are typically founder-led businesses operating in complex and fast-moving markets, and we are often the first law firm they appoint. That early involvement allows us to become a trusted partner from the outset, supporting teams as legal complexity increases and decisions become more consequential.

Many of our clients work extensively with data and emerging technologies, giving us deep, practical exposure to the legal issues that matter most to modern technology businesses. This experience has also shaped our approach to using AI to augment legal services, helping us to improve efficiency and responsiveness, while preserving the judgement and quality our clients expect.

Gazelle Law is led by Katie Cosgrove, an experienced in-house lawyer who has spent her career working inside high-growth technology businesses.

Katie has held senior legal roles at start-ups and scale-ups, including General Counsel positions, and has also worked at major international organisations and a leading Magic Circle law firm.

This in-house background informs our approach: pragmatic, commercially grounded, and focused on helping founders and leadership teams make confident decisions, rather than delivering abstract legal advice.

Our Approach

We work as an extension of our clients’ teams, providing senior legal support across key commercial and strategic matters.

Our model is deliberately lean and flexible, designed to give founders access to experienced legal leadership without unnecessary overhead or formality.

Gazelle Law exists to help technology founders and leadership teams operate with confidence, backed by legal advice that is practical, responsive, and aligned with how modern businesses actually work.

Join us

Gazelle Law is a growing team of experienced commercial lawyers who have built their careers in leading law firms and high-growth companies.

We work closely with founders and in-house teams at some of the UK’s most ambitious technology and AI companies, delivering senior legal support in a flexible, modern way.

We’re intentionally pioneering the use of AI tools to augment legal practice, using technology to remove friction, improve efficiency, and allow our lawyers to focus on what matters most: judgement, commercial insight, and client relationships.

We are always interested in hearing from outstanding lawyers who are looking for a different way to practise law. A way that combines high-quality work with autonomy and flexibility.

If that sounds like you, let’s chat.
