A Global Alts New York 2026 fireside chat explored how Andreessen Horowitz built a family office from scratch to serve the specific needs of tech founders navigating liquidity events. The conversation covered the structural difference between taxable and non-taxable investing, the Perennial approach to venture allocation, and why the a16z family office playbook challenges several institutional dogmas that have defined the LP landscape for decades.

The a16z family office playbook starts from a different premise than most wealth management firms. Andreessen Horowitz just closed a $15 billion fund. The principals decided to build a family office — Perennial — to serve the founders and executives in their network who are navigating liquidity events, concentrated stock positions, and the complexity of multi-asset-class wealth management for the first time. The firm runs Perennial on a break-even basis. “This is really a strategic endeavor to build a community,” the session guest explained. “We put our money where our mouth is.”

Why taxable investors need a different playbook

The taxable investor problem is the center of gravity for the a16z family office playbook. Non-taxable institutions — endowments, pensions, foundations — can optimize for pre-tax returns. Taxable investors cannot. “Two equal investments: private credit and real estate. Both could return 16%. Real estate could be 16% after tax for a taxable investor. Private credit could be as low as 4%.” That gap is structural and almost never reflected in the benchmarking frameworks that institutions use.

The real estate example recurred throughout. Traditional GP carry crystallizes on asset sale, which creates a taxable event. The Perennial approach prefers to hold assets, depreciate them to zero over their useful life, and tax-free cash out through refinancing. That is a fundamentally different holding period and a fundamentally different way to compensate the professionals managing the assets.

How the a16z family office playbook approaches venture allocation

On venture investing, Perennial runs a hybrid model. Some allocations go through fund-of-funds relationships for access and vintage diversification. Some go direct where the team has genuine edge. “Vintage diversification is non-negotiable,” the session guest said. “The one thing that every venture investor who has been doing this for more than a decade says is most important is vintage diversification, being able to deploy over large periods of time. All the returns in venture capital come from the best year vintages.”

The hybrid approach reduces the fund-of-funds headwind while maintaining the access benefits. The firm also builds in stage diversification — seed through late stage — and sector rotation awareness across vintages.

What institutional dogmas the a16z playbook challenges

The session guest pushed back directly on institutional constraints that family offices are not bound by. The three-year track record rule eliminates managers who have been in the industry for 15 years and simply have not crossed an arbitrary AUM threshold. The “outsource all macro to managers” rule means missing the AI wave entirely if you treat it as someone else’s problem. Over-diversification into 30 to 40 managers produces an expensive, illiquid index that underperforms the 70/30 you could buy at any brokerage for near zero cost. The a16z family office playbook is built on flexibility that the endowment model cannot accommodate.
