Private Capital Sidesteps VCs, Bets Directly on AI's Foundational Builders

A significant shift is underway in how the wealthiest investors back technology. Family offices and private wealth managers, traditionally limited to venture capital funds, are now writing direct checks to AI startups. The reason is straightforward: the most substantial value creation is happening long before a company considers an IPO, and the architects of AI infrastructure are seeking capital now.

Mitch Stein, founder of Arena Private Wealth, observes that companies are staying private longer. "A lot of money is being made well before companies go public," he said. His firm recently co-led a $230 million investment in AI chip company Positron, securing a board seat and moving from passive allocator to active participant.

The driving philosophy is defensive. "Your biggest risk is not having exposure to AI, not what could happen to your AI investments," Stein stated. His colleague, Ari Schottenstein, added that the foundational layer of AI is being constructed in real time, creating a narrow window for strategic positioning.

The data supports the activity. In February alone, family offices made 41 direct startup investments, nearly all AI-related. A BNY study finds 83% of these offices rank AI as a top five-year priority. Some are advancing beyond investment, incubating their own AI ventures or taking operational roles, applying the same entrepreneurial drive that generated their wealth.

This approach demands intense scrutiny. Arena's team, with institutional finance backgrounds, emphasizes deliberate vetting. "We are a very slow 'yes,' we say 'no' a lot," Schottenstein explained. For the Positron deal, validation included technical audits and analyzing the investor roster for credible co-investors like Arm.

The strategy results in concentrated, high-conviction bets. Instead of managing a broad portfolio, Arena executes only a few direct deals annually. Each commitment carries significant capital, reputational risk, and firm resources. "We don't model in failure on a single asset transaction," Stein said. This deep alignment, they argue, is what founders and co-investors now seek from their financial partners.
