Group Chief Executive Officer IBL Together Mauritius
Arnaud Lagesse
Leading one of the Indian Ocean's largest diversified groups — from a Mauritian house of enterprise into a regional operator and investor.
Arnaud Lagesse is Group Chief Executive Officer of IBL Together, the Mauritian group whose commercial lineage reaches back to 1830. In 2016 he initiated the amalgamation of GML Investissement Ltée and Ireland Blyth Limited to create IBL Ltd, and has since directed its expansion across the Indian Ocean and East Africa. In September 2025 he was elected President of Business Mauritius, the country's private-sector federation.
A career built on the long view: taking a family-founded Mauritian house, merging it with a 190-year-old trading company, and turning the result into a regional operator and investor that now trades in more than twenty countries.
Few business stories in the Indian Ocean have the shape of this one. Arnaud Lagesse began his working life in finance in Paris before returning to Mauritius in 1993 to join the family company — the group his grandfather, Joseph Lagesse, had set in motion with the acquisition of the Mon Loisir sugar estate in 1939. Twelve years later he became its chief executive.
What followed was less a series of transactions than a sustained argument about scale. A Mauritian group, however successful at home, is bounded by an island economy of roughly 1.2 million people. Growth beyond that ceiling requires either deeper diversification or a genuine move outward — and, usually, both. The 2016 amalgamation of GML Investissement Ltée with Ireland Blyth Limited answered the first question. The Beyond Borders strategy launched in 2021 answered the second.
The outcome is a group that describes itself as both operator and investor: nearly 300 companies working in retail, consumer brands and distribution, industrials and services — food, healthcare, energy, logistics, engineering, financial services and hospitality among them. It is a portfolio deliberately weighted toward the everyday economy rather than the speculative one, and it is increasingly earned outside Mauritius.
That trajectory is the subject of this website. It sets out what is publicly documented about Arnaud Lagesse's career and responsibilities, and places it in the wider context of Mauritian enterprise, regional expansion and the practice of long-horizon corporate leadership.

Seven turning points across three decades
Each of these moments is publicly documented. Together they trace a progression from finance, to stewardship of a family group, to the leadership of a listed regional conglomerate.
2005
Appointed Chief Executive
Twelve years after joining, he takes the chief executive's role at what was then the GML group.
2016

He initiates the merger of GML Investissement Ltée and Ireland Blyth Limited; IBL Ltd lists on the Stock Exchange of Mauritius on 14 July.
2018
A permanent base in Nairobi
The group opens a standing office in Kenya, formalising an East African presence rather than trading into it from a distance.
2021
Beyond Borders strategy
A deliberate reorientation toward regional growth, partnership with established local businesses, and renewable energy.
2025
President of Business Mauritius
Elected on 30 September to lead the national private-sector federation, succeeding Anil Currimjee. The group also adopts a four-cluster structure.
2026
IBL Together
Ten years after the merger, the group refreshes its identity as IBL Together around the values Truth, Trust and Together.
03 — Leadership in motion
Leadership is a practice, not a position
Running a diversified group means holding several time horizons at once: the quarter, the cycle and the decade. The discipline lies in refusing to let the first quietly consume the third.
01
Navigating change
Currency movements, freight costs, commodity swings and shifting consumer habits arrive together. Diversification is only useful if the centre can read all of them at once.
02
Resilient organisations
Resilience is structural: balance-sheet discipline, sensible gearing, businesses that do not fail in the same weather, and the willingness to exit what no longer fits.
03
Human capital
Lagesse has repeatedly named talent — attracting it, developing it, keeping it — as Mauritius's central constraint, and by extension the group's.
04
Culture and trust
The group's stated values are Truth, Trust and Together. In a federation of nearly 300 companies, shared behaviour is what makes devolved authority workable.
“It requires astute business acumen, and provocative, courageous and forward-thinking undertakings to maintain leadership.”Arnaud Lagesse Quoted in The CEO Magazine, executive interview
An island economy that decided to trade its way out of its own size. Mauritius: sugar, then textiles, then tourism, then financial and business services — and now a gateway position between Africa and Asia.
04 — Business & Mauritius
The economy behind the enterprise
No account of Mauritian corporate leadership makes sense without the country's own trajectory — one of the most-studied economic transformations in the Indian Ocean.
At independence in 1968 Mauritius was a single-crop economy with few obvious advantages: no hydrocarbons, no significant minerals, a small domestic market and a long distance to every major trading partner. The successive additions of an export processing zone, a tourism industry, a financial and business services sector and, more recently, technology and logistics activity turned that constraint into a strategy.
The result is an economy that behaves like a trading platform: bilingual, common-law and civil-law literate, connected by treaty and by air and sea routes to Africa, India and Asia. For a domestic group, that platform is the enabling condition for regional expansion — a base from which to operate elsewhere, rather than merely a market to serve.
It is also a demanding place to operate. A small labour market makes specialist skills scarce; an open economy imports its inflation; and dependence on tourism and financial services concentrates exposure to decisions made far away. These are the conditions in which Mauritian groups have had to build.
“Mauritius is ideally situated and structured to be Africa's preferred partner.”Arnaud LagesseQuoted in The Business Report

Four forces shaping the decade
Economic reordering. Supply chains that optimised purely for cost are being rebuilt for resilience and proximity. For groups positioned between Africa and Asia, that redrawing is an opportunity as much as a disruption.
African consumption. The centre of gravity in East African retail has moved toward organised, formalised grocery. IBL's investment in the Kenyan retailer Naivas — USD 145 million alongside partners in 2022, with a further subscription in 2023 — is the clearest expression of that thesis in the group's portfolio.
Technology and expectation. Consumers in Nairobi, Antananarivo and Port Louis increasingly expect the same digital service standards. Meeting that expectation is a capital and capability question, not a marketing one.
Energy and the environment. When the group set its strategy in 2021 it identified renewable energy as a sector with strong potential, and has since taken positions in solar generation in East Africa. For an island economy exposed to imported fuel and to sea-level risk, this is not a peripheral concern.
