CNBC’s Family Office 15: Robert Frank Ranks the Most Active U.S. Family Offices Using FINTRX Data

What Is the Family Office 15?

The Family Office 15, curated by Robert Frank and the Inside Wealth Team at CNBC, identifies the 15 most active U.S. single family offices based on direct investment activity in 2025. Using FINTRX’s comprehensive family office database, they analyzed transaction volume, industry focus, and investment pace to determine which firms are deploying capital most aggressively in private markets.

The ranking offers rare transparency into one of the most influential yet historically opaque segments of the investment ecosystem. Unlike institutional investors, family offices often invest quietly and directly into companies, making high-quality, continuously updated family office data essential for tracking real activity.

Who Tops the List?

Leading the 2025 ranking is Hillspire, the family office of former Google CEO Eric Schmidt. Hillspire recorded 15 direct investments so far this year, with a strong concentration in artificial intelligence and next-generation technology companies.

Investments highlighted in the report span:

• AI voice and automation platforms
• Advanced fusion energy developers
• Enterprise software companies
• Luxury and technology-enabled services

Hillspire’s activity reflects a broader trend among leading family offices: increasing conviction in artificial intelligence, deep tech, and frontier innovation sectors.

Broader Family Office Investment Trends in 2025

Beyond the headline ranking, the Family Office 15 underscores several key themes shaping family office investment strategy:

1. Direct Investing Continues to Accelerate

Family offices are expanding beyond traditional fund allocations and increasing participation in direct deals, co-investments, and venture opportunities.

2. AI and Advanced Technology Dominate

Artificial intelligence, machine learning infrastructure, energy innovation, and next-generation software are attracting significant family office capital.

3. Agility in Private Markets

Family offices can move quickly, write flexible checks, and pursue long-term thematic strategies aligned with generational wealth objectives.

For asset managers and fund sponsors, these trends reinforce the importance of identifying which family offices are actively deploying capital and how their investment mandates are evolving.

The Role of FINTRX in Mapping Family Office Capital Flows

Family offices have historically been difficult to track due to inconsistent reporting, varied definitions, and fragmented transaction visibility.

By leveraging FINTRX’s AI-driven data ingestion, continuous transaction monitoring, and verified family office database, CNBC was able to produce a ranking grounded in measurable investment activity rather than anecdotal reputation.

The Family Office 15 demonstrates how structured private wealth intelligence can:

• Identify the most active family offices by deal count
• Surface sector concentration trends
• Track direct investment momentum
• Provide greater transparency into private capital markets

For professionals raising capital or distributing alternative strategies, access to timely, accurate family office intelligence provides a significant competitive advantage.

Why This Matters for Asset Managers and Capital Raisers

Family offices represent one of the fastest-growing pools of private capital globally. With long-duration capital, strategic flexibility, and increasing appetite for direct investments, they are playing a larger role in venture, growth equity, private credit, and real assets.

Understanding which family offices are most active—and where they are investing—enables fund managers to:

• Prioritize high-intent family office prospects
• Align outreach with demonstrated sector interests
• Engage decision-makers with relevant, data-backed insights
• Position strategies alongside real-time capital deployment trends

The Family Office 15 is more than a ranking. It is a data-backed snapshot of where private wealth capital is moving in 2025. For firms seeking to better understand the family office landscape, investment trends, and capital flows, actionable private wealth intelligence is no longer optional; it is foundational to modern distribution and capital formation strategy.
