Top Tier Capital Partners, a private-equity asset-management firm focused on venture capital, has hired veteran industry executive Sean Warren to lead the firm's compliance and legal efforts.

Warren, Top Tier's new counsel and chief compliance officer, will oversee a robust compliance program designed to keep the firm abreast of the fast-changing regulatory environment for investment firms. He also will offer legal counsel to the firm and assist with the formation of new products and strategic initiatives.

Before joining Top Tier, Warren had a long career in investment management in the U.S. and Asia. He worked as the president and chief operating officer of Robertson Stephens Asset Management, where he led business-development initiatives and was responsible for all operational aspects of the business. Prior to that, Warren spent nine years as managing director and general counsel for Soros Fund Management, the investment advisor to George Soros's Quantum Group of Funds, which had up to $20 billion under management during Warren's tenure there.
