Mavros
Mavros Asset Management · Outsourced CIO

Your Outsourced Chief Investment Office.

We manage the whole portfolio at full discretion, public and private, to one fiduciary standard. It's the institutional investment office most families and institutions would otherwise have to build themselves.

Your Private Investment Office

Running a serious portfolio is a job in itself. Setting the policy, allocating across public and private markets, finding managers and checking their work, sizing the illiquidity, watching the risk, reporting the truth. Most families and institutions can't staff all of that, and shouldn't have to. That's what an outsourced chief investment office does, at full discretion, as a fiduciary.

Mavros becomes that office. It's how the old family investment houses, Rockefeller among them, held onto fortunes across generations that never met: one team, one book, every asset class, one standard. You keep the goals and the governance. We carry the portfolio.

Who we serve

Who We Manage Money For

Families & Family Offices

Wealth that needs an institutional investment office and shouldn't have to build one. We become that office.

Endowments & Foundations

Perpetual capital with a spending mandate, where both the investment and the governance around it have to hold up for decades.

Institutions & Retirement Plans

Boards and committees carrying a fiduciary duty they can't fully staff, who would rather hand discretion to a team that answers for the result.

The difference

We Take the Portfolio

The difference is discretion. A consultant hands your committee a stack of recommendations and leaves the implementing, and the results, to you. We just run it.

Traditional consultant
  • Recommends managers and strategies for your committee to weigh.
  • Advises when called upon. The committee still owns the implementation.
  • You keep the internal staff, the systems, and the coordinating.
  • The outcome stays your responsibility.
Mavros OCIO · full discretion
  • Takes full responsibility for managing the portfolio and its performance.
  • Makes and implements every call (allocation, manager selection, rebalancing, trading) under your policy statement.
  • Stands in for an internal investment office and its systems.
  • Acts as a fiduciary, and answers for the result.
Why discipline

Roughly nine in ten family fortunes are gone by the third generation. The market is rarely what did it. What's usually missing is a plain, disciplined way of holding the money.

The process

How We Actually Run the Money

No two portfolios are alike, so we skip the models and build each one to fit. The method underneath stays the same, every time.

01

Discovery

We start with your objectives, liabilities, liquidity needs, time horizon, and constraints. No model portfolio pulled off a shelf.

02

Investment Policy Statement

The blueprint. Roles, goals, benchmarks, allocation guidelines, and restrictions, written down and governing everything after it.

03

Asset Allocation

The mix across public and private that drives most of the return, sized to what you actually need rather than what's easy to sell.

04

Manager Selection

High-conviction picks from a screened universe, chosen on a repeatable process and the numbers. Not on a name or a good pitch.

05

Portfolio Construction

We assemble the managers and exposures into one coherent book, size the illiquidity on purpose, and keep the risks legible.

06

Risk Management & Monitoring

Ongoing oversight against the policy statement, disciplined rebalancing, and reporting that tells you the truth, on schedule.

The philosophy

Six Things We Believe

None of these are new. That's the point. The edge here isn't a secret. It's the discipline to hold the boring, right answers when the market gets loud.

01

Allocation Decides Most of It

The mix of assets drives most of what a portfolio returns over time, far more than any single clever pick. So we get the mix right first, before anything else.

02

Active Only Where It Earns Its Fee

Where markets are efficient, we index and keep the fee. We pay up for active management only where real skill, access, or structure can add value. Most of the time it can't.

03

Risk Is Permanent Loss, Not Volatility

A price that moves isn't the risk; it's the cost of admission. The real risks are quieter: capital impaired for good, inflation eating it a little each year, a plan abandoned at the bottom.

04

Build for Uncertainty, Not Forecasts

We don't bet the portfolio on a view of next year. We build it to survive whatever actually shows up, because the forecast tends to be wrong right when it counts.

05

Judged by What You Keep

What matters is what you keep after fees, after taxes, after the frictions nobody quotes you going in. The headline number and the money that lands in your account are rarely the same.

06

Diversification Requires Access

Real diversification means reaching return streams most portfolios can't touch. More tickers of the same market won't get you there, and that gap is why we run a private arm.

One book, two arms

Public and Private, One Book

Every portfolio needs both. Assets you can sell on a Tuesday, and assets you're paid to lock away. We run each with the same discipline and size them to what you actually need.

Public Markets

The liquid core. Global equities and fixed income, indexed where markets are efficient and active only where it pays. This is the ballast: liquidity, transparency, and money you can reach without notice.

Global EquitiesFixed IncomeLiquid AlternativesCash & Ballast

Private Capital

The illiquidity premium, and our in-house arm: venture, private equity, private credit, and real assets, sourced and underwritten directly. Longer lockups, higher potential return, and access that used to be reserved for institutions. It's a separate thing from Global Wealth, our client-facing wealth platform.

On keeping it

“It requires a great deal of boldness and a great deal of caution to make a great fortune; and when you have got it, it requires ten times as much wit to keep it.”
