Fund Structure & Independence
Mentawai Ventures operates with a 12-year investment horizon. Its legal separation from the core infrastructure companies — the seven OpCos and their SPVs — is deliberate: it allows the fund to pursue opportunistic investments, accept different risk profiles, and engage with earlier-stage companies. Ring-fencing ensures volatility in the ventures portfolio does not affect infrastructure balance sheets, and infrastructure investors are not exposed to venture-stage risk.


Seven Target Sectors
The fund invests across IT and AI, IoT and sensor systems, fintech and green finance, cooling technology for data centres, aerospace aligned with seaplane manufacturing, aggrotech and precision agriculture, and construction systems including modular building and low-carbon materials. Portfolio concentration limits require no single sector exceeds 25% of committed capital, ensuring genuine diversification.
Three-Phase Deployment
The fund operates across three defined phases. Deployment focuses on initial capital commitments across the diversified portfolio, prioritising companies creating direct operational value. Follow-on allocates reserve capital to the highest-performing portfolio companies for growth and integration. Exits and legacy transition manages realisation through M&A, strategic sale, or integration into the Mentawai One OpCo structure.


The Mensarius Oath
All investment decisions are subject to the Mensarius Oath — the programme's code of ethical investment conduct. Fund managers evaluate investments not only on financial return but on people impact, environmental stewardship, responsible technology deployment, and business practice integrity. Taking an oath — rather than signing terms and conditions — creates a different psychological and social contract for those who deploy capital.
People
We invest in ways that dignify, protect, and create opportunity for the people touched by our activities — workers, communities, indigenous peoples, and future generations.
World
We recognise that the natural world is the source of all economic value and that its protection is not in conflict with prosperity — it is the foundation of it.
Technology
We deploy technology in service of human and ecological flourishing. We reject the use of technology to extract value from people without their informed consent.
Business Practices
We conduct our business with transparency, honesty, and the discipline of independent verification. We do not make claims we cannot support.
Veto Power and Accountability
The Mensarius Oath carries governance weight. Investment committee members who take the Oath can invoke it to veto investment decisions — including those that meet financial return criteria — where they judge that the investment materially contradicts the Oath's commitments. This veto right is documented in fund governance documents and investment committee charters, making the ethical dimension of decision-making legally operative rather than merely advisory.

Invest in Innovation
Technology-led investment opportunities across seven sectors — governed by the Mensarius Oath and the long-horizon logic of the Mentawai One programme.
