ResponsAbility Investments AG

ResponsAbility Investments was founded in 2003 in Zurich, Switzerland, as a dedicated impact asset manager focused on financing growth in developing and emerging markets. The firm was initially spun out of Swiss bank Credit Suisse and later became an independent entity; it operates as a regulated asset manager with a multibillion-dollar portfolio. The senior leadership includes CEO Rochus Mommartz, who has overseen diversification into broader investment strategies. The firm targets debt and equity investments across climate finance, energy access, sustainable agriculture, financial inclusion, and basic infrastructure. Geographically, ResponsAbility operates across Africa, Asia, Latin America, and parts of Eastern Europe, with a network of local offices in Mumbai, Nairobi, Lima, Singapore, and elsewhere. The firm typically provides direct private credit and equity to SMEs and project developers, and also manages funds of funds and custom mandates for institutional investors. It has a documented track record of over 300 transactions, with a focus on measurable development outcomes. With $5.8B in committed capital and a staff of around 250 professionals, ResponsAbility manages multiple vehicle types, including closed-end impact funds, open-ended credit funds, and separate accounts. The firm's investor base includes development finance institutions (DFIs), pension funds, insurance companies, and foundations. In 2024, ResponsAbility announced a $400M allocation from a major European pension fund toward its climate finance strategy, marking a notable uptick in institutional demand. ResponsAbility's structural differentiator is its permanent on-the-ground sourcing network in over 60 emerging markets combined with a rigorous impact measurement framework. Unlike many impact asset managers that rely on intermediaries, the firm originates and monitors deals through local investment professionals, reducing agency costs and capturing proprietary deal flow.

Frequently asked questions

Who runs investment decisions at ResponsAbility Investments?

Investment decisions are led by CEO Rochus Mommartz and the firm's investment committee, which includes regional heads for Africa, Asia, and Latin America. The firm also relies on country-based local teams for origination and due diligence, reflecting its decentralized operating model.

How does ResponsAbility source proprietary deal flow?

The firm maintains investment professionals deployed across eight offices in emerging markets, enabling direct origination of loans, bonds, and equity. This network produces proprietary deal flow from SMEs, microfinance institutions, renewable developers, and agribusinesses that institutional investors otherwise rarely access.

What investment stages does ResponsAbility typically target?

ResponsAbility typically invests in growth-stage and established private companies, project finance, and structured credit. It does not focus on early-stage venture capital, instead favoring enterprises with proven business models that need capital for expansion.

Does ResponsAbility participate in fund commitments or only direct deals?

The firm manages both direct private debt and equity investments alongside fund-of-funds mandates. It also structures custom separate accounts for institutional clients, allowing them to combine direct co-investments with commingled exposure.

Which sectors does ResponsAbility explicitly focus on?

The firm targets climate finance, energy access, sustainable agriculture, financial inclusion, and basic infrastructure. It explicitly avoids fossil fuel extraction, tobacco, and defense-related businesses, consistent with its impact mandate.

How is ResponsAbility structured relative to its origins at Credit Suisse?

ResponsAbility was originally a part of Credit Suisse but became an independent asset manager after a management buyout. It is no longer affiliated with Credit Suisse, though it continues to receive capital allocations from multiple Swiss and European institutional investors.

Where does the underlying capital that ResponsAbility manages come from?

The firm's capital primarily comes from development finance institutions, European pension funds, insurance companies, and foundations. It does not disclose wealth origin of any individual family, as its institutional structure does not center on a single family office.
