Jean Kacou Diagou, Ivorian entrepreneur who built NSIA into a Pan-African financial empire

In 1995, the Ivorian insurance executive left a senior position at multinational insurer UAP to establish the Nouvelle Société Interafricaine d’Assurance (NSIA). Three decades later, the group has expanded beyond insurance into banking, asset management, technology and digital finance, with operations across approximately 12 African markets.

Diagou’s strategy combined acquisitions, regional expansion and international partnerships to build an African-owned financial-services group from Abidjan. His story is not simply about wealth; it is about how an entrepreneur used insurance as the foundation for a Pan-African financial empire.

From insurance to banking

The defining moment in NSIA’s transformation came in 2006, when the group acquired BIAO Côte d’Ivoire, creating the foundation for its banking business. The acquisition transformed NSIA from an insurance company into a broader financial-services group, combining banking and insurance under one African-owned platform.

NSIA subsequently expanded its financial-services portfolio into asset management, capital markets, technology and digital finance, while continuing to build its insurance and banking operations across West and Central Africa. The group’s regional footprint now stretches across 12 countries, including Côte d’Ivoire, Benin, Togo, Senegal, Ghana, Nigeria, Cameroon, Gabon and Congo.

Its expansion has been driven by a mixture of acquisitions, organic growth and strategic partnerships. One of its most notable modern partnerships came through Orange Bank Africa, where NSIA holds a 25% stake alongside Orange. The digital banking venture strengthened the group’s push into technology-driven financial services.

The challenger becomes the consolidator

The evolution of NSIA is particularly striking because Diagou eventually moved from competing against international insurers to acquiring their African assets.

In 2023, NSIA acquired four Sanlam insurance subsidiaries in Togo, Gabon, Congo and Guinea, strengthening its position across the region. The move echoed NSIA’s earliest expansion strategy. 

In 1996, the young Ivorian insurer had acquired operations from AGF. Decades later, it had grown sufficiently to acquire assets from another major international insurance group.

That transformation captures the scale of Diagou’s achievement. What began as a CFA300 million ( over half a billion dollars) insurance company became a regional financial institution with banking, insurance and investment businesses.

Family control strengthens

The latest chapter of Diagou’s story has centred on ownership.

In April 2025, his family investment vehicle, Manzima Holding, acquired National Bank of Canada’s 22.6% stake in NSIA Participations. The transaction increased Manzima’s holding from 46.67% to 68.73%, making the Diagou family the dominant shareholder in the holding company.

The transaction followed Manzima’s acquisition of Amethis’ 6% stake in 2024 and marked a further consolidation of family ownership. The development is significant because NSIA had attracted international institutional capital during its expansion. Swiss Re, National Bank of Canada and Amethis were among the institutions associated with the group’s shareholder base.

Building beyond one generation

Diagou’s legacy is also becoming a family enterprise.

His daughter, Bénédicte Janine Kacou Diagou, has held senior responsibilities within NSIA and became chair of the group’s board in 2017.

The transition gives the group a new challenge: preserving the entrepreneurial culture that helped NSIA expand while strengthening the governance required to manage a complex, multinational financial institution.

For Diagou, however, the achievement is already substantial. NSIA has evolved from a single insurance company founded in Côte d’Ivoire into a diversified African financial group. Its banking arm has become a major regional institution, while its insurance operations continue to provide the foundation on which the group was built.

Recent developments underline the scale of that transformation. In 2026, NSIA Banque Côte d’Ivoire reported assets exceeding $5 billion, while the group secured a $34.2 million facility from British International Investment to expand lending to SMEs and women entrepreneurs.

Diagou’s story, therefore, is less about an uncertain personal fortune than the institution he created.

From 300 million CFA francs in 1995 to a financial group operating across 12 African markets, Jean Kacou Diagou has spent three decades proving that an African-owned financial institution can grow beyond its home market and compete at regional scale.

The insurance executive who left UAP to build his own company did not merely create another insurer. He built NSIA into an African financial-services group, and turned a modest CFA300 million bet into a Pan-African business empire.
