OUR TEAM

You will always know who is running your mandate.

Our investment team is specialist and deliberately small. Investment strategy, research and client consulting stay in-house, because the intellectual capital of this business is what keeps the philosophy and the process solid and repeatable.
THE TEAM

35 specialists.

One standard.

Our team is deliberately boutique. Small enough that your fund is known by name rather than by account number and specialist enough that the technical work stays in-house.

Years of collective
experience
Every mandate is run by people who have worked through more than one full market cycle, and who are still here to answer for the decisions they made in the last one.
Investment strategy & advisory
Asset-liability modelling, investment policy design, liabilities analysis, strategic asset allocation and investment strategy design.
Manager research & selection
Continuous research across local and global managers, independent due diligence and ongoing monitoring. Evidence-led and reviewed, not set once and forgotten.
Implementation & risk
Portfolio construction, blending, rebalancing and investment risk management. Strategy and execution sit together, so nothing is lost between the recommendation and the result.
Reporting & governance
Board-ready performance monitoring and reporting, and practical navigation of COFI and Regulation 28.
LEADERSHIP

The people accountable
for your fund’s outcome.

Mentenova is owned and managed by the people who lead it. There is no external shareholder, and no unnecessary layers between a decision and the person answerable for it. This is the team that leads the business and its mandates.
