Regulatory Strategy. Market Access. Executive Search. Governance.

Trusted advisor to trading firms navigating EU regulation, licensing, senior hiring, and board-level strategy.

About me

I advise and support firms active in EU financial markets on strategic regulatory, governance and market-access matters.

I have over 25 years of experience in European financial markets, having worked as a financial journalist, compliance officer, lobbyist, board member, independent non-executive director and consultant.

Today, I advise proprietary trading firms, trading venues and brokers on how to navigate and position themselves within the European regulatory landscape — whether as an external advisor or as an independent non-executive director (INED).

I also support non-EU firms seeking to establish or expand their presence in the EU, including with market-entry strategies and regulatory licensing. Where specialist expertise is required, I connect clients with trusted legal and compliance advisors, tax specialists and notaries.

Having worked in and around the trading industry for more than 25 years, I have built an extensive network across European financial markets. Through Lex Mercatus, I also help firms identify and recruit experienced professionals for senior compliance, regulatory and leadership roles.

Current activities:

  • Boardroom advisor to trading firms, brokers and exchanges regarding regulatory challenges
  • Executive search for senior regulatory and compliance positions in the trading industry
  • Independent Non-Executive Director (INED) at fairCT
  • Chair of the Association of Proprietary Traders (APT)
  • Chair of the Supervisory Board of Nino Options
  • Advisory Board Member of BrightFunded

Past activities:

  • Ex-Head of EU Public Affairs at Optiver
  • Former board member and vice-chair of the FIA European Principal Traders Association (FIA EPTA)
  • Former Senior Compliance Officer at an HFT firm
  • Former policy officer and supervisor for exchanges at the Dutch Authority for the Financial Markets (AFM)
  • Former financial journalist at Betten Financial News (acquired by DJ Newswires)
  • Various executive and non-executive board and advisory roles across the industry

What I Bring to the Table

With over 25 years of experience in financial markets, I bring a rare combination of regulatory insight, industry perspective, an extensive network and board-level judgement. I’ve worked in various roles (e.g. board member, INED, compliance officer, consultant,  head of public affairs, policy officer  and regulator) at different organisations (e.g. trading firms, markets regulator, market data firm), all with a strong regulatory component — so I understand the full spectrum of how rules are made, interpreted, implemented and enforced.

Why my Clients Trust Me

Clients highly value my deep network across the Dutch and European trading landscape (both at the public and the private sector), my strategic approach to complex regulatory questions, and my ability to connect firms with the right experts — whether it’s for licensing, advocacy, or building a strong compliance team. I’m known for being independent, discreet, and results-driven.
