About Me

I'm a partner in our international Corporate Group in London. I specialise in venture capital, focusing on the financing of high-growth organisations.

Acting for top-tier investors and high growth companies, my transactional experience includes advising in respect of companies at all stages of their life-cycle: from their incorporation and commercial set-up, to scale-up and all the way through to exit and beyond. As well as venture equity, I am highly experienced in growth debt/venture debt financings, and regularly act for some of the leading lenders in the market.

I have a particular interest in corporate venture capital, and have acted in relation to a number of financing transactions involving strategic partnerships (both directly and through innovation funds). My experience acting for companies at all stages of their life-cycle means that I have a thorough understanding of the issues and benefits which can arise when a large organisation invests in earlier stage companies.

Many of the organisations I work with are involved in disruptive technologies, operating at the cutting-edge of their industry, often on a multi-jurisdictional basis. As a result, I often work with colleagues from our international offices, as well as our sector specialists. I have significant experience assisting high-technology companies across the technology, communications, energy and utilities and life sciences sectors.

I'm also highly experienced in M&A transactions (often on a cross-border basis), and general corporate advisory work.
