KOIS Invest

Charles-Antoine Janssen and François de Borchgrave serve as the firm's Managing Partners and lead all investment decisions. Janssen's background includes strategy consulting at McKinsey; de Borchgrave brought private-banking and microfinance experience to the founding partnership (per ImpactAlpha, 2020). Day-to-day investment committee work also draws on a small team of investment directors covering venture, outcomes finance, and real estate.

KOIS sources through its network of European development finance institutions, philanthropic foundations, and government ministries—relationships built during the structuring of Belgium's first social-impact bonds. The firm's role as an architect of blended-finance vehicles grants it early visibility into health-tech and education startups that are positioned for outcomes-based contracts. In India, its presence was established through development-impact bonds, which created a pipeline of NGO and social-enterprise partnerships not commonly accessible to Brussels-based managers.

KOIS Invest operates as a regulated asset manager, not a family office. The firm pools third-party capital from European family offices, high-net-worth individuals, and institutional investors including the European Investment Fund. In 2017 it launched KOIS Capital Partners, a dedicated alternative investment fund vehicle, which further formalized its external-capital management model.

KOIS primarily engages in direct investments—taking equity stakes in health-tech and education ventures and structuring bespoke outcomes-based financing instruments. It also raises and manages its own pooled vehicles, such as the blended-finance funds it has structured with development finance institutions. The firm does not operate as a fund-of-funds; its capital is deployed through proprietary deal structures rather than commitments to third-party GPs.

On the venture side, KOIS targets early-stage European companies with validated models and an imminent path to outcomes-based or public-sector contracts. Its outcomes-financing practice engages at the proof-of-concept stage for social interventions, typically funding the initial delivery phase of a contract before repayment triggers. The firm's affordable-housing activity spans both ground-up development and acquisition-rehabilitation projects.

KOIS Invest itself is a for-profit asset manager and takes a management fee and carried interest on its vehicles. However, the firm frequently designs investment structures that incorporate philanthropic first-loss capital provided by foundations. These foundations are external clients or partners, not entities under common ownership with KOIS. The separation between the firm's private-equity activities and its outcomes-based contracts is maintained through distinct fund vehicles and segregated limited-partner rosters.

KOIS co-invests selectively with development finance institutions and impact-oriented family offices, particularly on affordable-housing and health-tech deals where its structuring expertise adds value. It does not advertise a broad co-investment program, and its bespoke blended-finance vehicles are typically KOIS-led rather than participation stakes in another sponsor's fund. In the outcomes-financing space, KOIS often acts as the sole arranger, bringing in outcome payers and service providers rather than co-sponsoring with peer asset managers.
