May 20224 min read

Zurich, 6 May 2022 – With the acquisition of responsAbility Investments by M&G now complete, the decision has been taken to strengthen the top leadership team at this innovative and quickly growing sustainable investment firm. Two internal candidates have been selected to join the Executive Management: Tara Hesse will join as Chief Operating Officer and Martin Heimes will join as Head of Private Debt.

Tara Hesse joined responsAbility in 2013 with extensive experience in corporate and in-house legal counsel in the financial industry, and prior to taking the role of Chief Operating Officer, she was the Head of Legal & Compliance. As a manager of an international team, covering corporate and transaction related matters in Europe and emerging markets and a director of responsAbility subsidiaries in Africa, Georgia, India and Thailand and former entities in Luxembourg and Norway, she brings broad international capabilities to her new role and has demonstrated a deep understanding of the complexities of global business operations, making her an ideal fit as the Chief Operating Officer. Tara stated, “A profound understanding of the business is key not only for a legal & compliance department to provide effective services but for all core operations within a company. Having been part of the company’s journey during a period of extensive growth and innovation in various roles, I am excited to expand my responsibilities and join the executive management team for this next chapter of making the planet a more sustainable place.” Martin Heimes has been with responsAbility since 2009 and has been indispensable to the company’s growth. Beginning his career in consulting and fund management in development finance, he became the Co-Head of Financial Inclusion Debt, the firm’s largest business line, in 2018. In his new role heading up all of the Private Debt Teams, the company hopes to capitalize on the strong leadership that he has demonstrated through the years to drive new opportunities in Private Debt across all sectors, from financial inclusion to climate to sustainable food. Martin stated: “With the M&G acquisition, a new phase of the company starts, pushing us to expand impact investing even further. Enlarging our activities on the Private Debt side will be a key part, and I look forward to leading and driving it.” Rochus Mommartz, CEO of responsAbility Investments, confirmed: “We are pleased to welcome Martin and Tara to our Executive Management team. They have both been key players in the success of the company for a long time and this is a natural expansion. We are confident that their depth of experience and strong leadership will be instrumental to the company’s further success.” The rest of the Executive Management Team continues as before, with Rochus Mommartz as Chief Executive Officer, Stephanie Bilo as Chief Client & Investment Solutions Officer, and Michael Fiebig as Head of Private Equity.
