According to FINTRX data, family offices deployed capital across 112 transactions and 99 unique companies in August 2026, an increase from July's 107 transactions, with AI reaching its highest concentration of the year and energy investing posting its strongest month to date.

Here's a breakdown of where the capital went:

AI Reached a New High in August
Artificial intelligence appeared as a sub-sector in 34 of 112 transactions—nearly one in three deals—making August the most AI-intensive month in the Q2/Q3 dataset. The theme ran across every stage and multiple geographies.
Notable AI-focused deals included:

• CodeRabbit - $143M Series C (Hirtle, Callaghan & Co.)
Series A Led All Deal Stages for the Third Consecutive Month
Series A was again the most common transaction type, accounting for 20 deals—matching June and July exactly. The full stage breakdown showed a notable shift from July: Seed activity nearly doubled, Pre-Seed climbed to 8 deals, and Acquisitions dropped from 18 in both June and July to just 12 in August. Private Equity also pulled back to 6 deals, suggesting family offices tilted back toward earlier-stage deployment after July's growth-stage lean.
The full stage breakdown:
• Series A: 20 transactions
• Seed: 15 transactions
• Venture: 14 transactions
• Series C: 13 transactions
• Series B: 12 transactions
• Acquisition: 12 transactions
• Pre-Seed: 8 transactions
• Series D: 6 transactions
• Private Equity: 6 transactions
• Series G: 3 transactions
• Series E, Post-IPO Equity, Undisclosed: 1 each
Energy Had Its Strongest Month of the Year
Energy, Materials & Agriculture appeared in 16 August transactions—its highest count across the full May through August dataset. The two standout rounds were Form Energy's $750M Series G, with Capricorn Investment Group participating, and Base Power's $1B Series D, with a16z Perennial participating.
Other energy rounds with family office involvement included:
• Emerald AI - $150M Series A, spanning energy and AI (Emerson Collective, Fahr LLC, Foris Ventures, and Olayan Group)
• Mariana Minerals - $310M Series B (a16z Perennial)
• Voya Energy - $35M Series A (Foris Ventures)
• TerraBlaster - $12.5M Seed (Builders Vision)
Foris Ventures participated in three energy-adjacent rounds in August alone, making it the most concentrated energy investor of the month.
Early-Stage Activity Rebounded Sharply
Seed and Pre-Seed rounds totaled 23 transactions in August—more than double July's 10 and the highest combined early-stage count since June. YZi Labs (CZ Family Office) was the primary driver, participating in 10 transactions—the majority at Seed and Pre-Seed—across blockchain, cryptocurrency, and fintech companies in Hong Kong, Singapore, and Colombia. Other active early-stage participants included a16z Perennial, Builders Vision, Dolby Family Ventures, and Artha India Ventures.
Healthcare Rebounded from July
Healthcare & Life Science appeared in 16 August transactions, up from 9 in July.
Notable rounds with family office participation included:
• LifeMine Therapeutics - $188M Series E (Bezos Expeditions)
• Epicrispr Biotechnologies - $90M Series C (Duquesne Family Office)
• InduPro - $77M Series B (Emerson Collective and Euclidean Capital)
• Stability AI - $76M Series B (Hillspire LLC)
• Hopscotch Primary Care - $53M Series D (Foris Ventures)
• Network Bio - $50M Venture (Breyer Capital and Thiel Capital)
• Remepy - $36M Series A (Ofer Global)
• Leal Therapeutics - $30M Series A (Euclidean Capital)
Financial Services Acquisitions Pulled Back
Acquisitions dropped to 12 in August, down from 18 in both June and July.
Active acquirers included:
• Wealth Enhancement Advisory Services - 3 deals
• MAI Capital Management - 2 deals
• Corient, Modera Wealth Management, Merit Financial Group, Balentine, and Sequoia Sentinel - 1 deal each
The pullback in acquisition volume may reflect seasonal dynamics or a temporary pause in the consolidation pace that defined the prior two months.
Co-Investments Hit a New High
11 companies attracted multiple family office investors in August, matching July's count—but the depth of syndication increased. Emerald AI drew four separate family offices into a single Series A round. Etched, Whatnot, Rillet, InduPro, Network Bio, Moove, Volta Infra Holdings, Farmbot, River Mobility, and Centricity each saw two family offices participate.
For fund managers, this level of co-investment activity signals that family offices are increasingly comfortable participating in the same rounds alongside one another—and that relationship intelligence within this channel is becoming a competitive advantage.
What This Means for Fund Managers
August reinforced several trends that have defined the summer. AI is now a structural feature of family office deal flow, not a thematic bet—it appeared in nearly a third of all transactions. Energy is increasingly attracting large-check family office participation, particularly from climate-focused offices like Capricorn, Foris Ventures, and Builders Vision. Early-stage appetite is back after July's pullback. And a16z Perennial's active month, participating in four of the ten largest rounds, underscores how a small number of highly active family offices are shaping the market.
For fund managers raising capital from family offices, knowing which investors are active in your sector and stage—and reaching the right contacts within those organizations—is where FINTRX comes in.
