Simon specialises in advising clients (ranging from fast-growth start-ups to internationally listed companies, as well as governing bodies, Middle Eastern and African governments, major clubs, sponsors, intermediaries and athletes) on a range of transactional, IP and regulatory issues – including in particular, clients operating in the advertising, retail, property (including facilities management), healthcare and crypto industries.
He is widely seen as an expert in his field and consequently is often featured in the national and international press – including making appearances on Sky News, ITV and BBC, as well as being quoted across all of the major national news titles. Simon also recently co-authored the chapter on Financial Regulation in the leading Football Law textbook “Football and the Law” published by Bloomsbury Publishing.

He has a long history of advising fast-growth SaaS/AI-led businesses on a range of commercial, IP and IT law matters. In particular, he has worked on several high profile proptech, adtech, retail, leisure, esports and betting & gaming deals.
Recent highlights include advising a fast-growth Swedish technology SaaS company on a number of its most important commercial agreements opposite its key customers and assisting several FTSE 100/S&P 500 companies on major IT outsourcing, global networks and data centre contracts.
Simon completed secondments with Dell and Tesco whilst at his previous firm.
Sport
Simon regularly works on significant broadcasting matters, image/digital rights agreements, sponsorship arrangements and international transfers.
Recent experience includes acting on what has been reported as boxing’s first ever billion dollar deal, negotiating a major Premier League sponsorship contract for a fast growing African country, advising a high-profile player on reportedly one of the top three largest contracts in Premier League history and assisting on multiple F1-related matters (including negotiating a naming rights deal for a major F1 team and a range of commercial/drivers contracts for a number of drivers).
On the regulatory side, he advises clients on an array of issues including Financial Fair Play, Third Party Ownership and Intermediaries Regulations, as well as several governing bodies and other non-sports clients on a wide selection of commercial law and privacy-related matters.
