For a long time, gaining access to promising startup equity typically required investing through the funds managed by leading venture capital firms. However, the current surge of interest in artificial intelligence is reshaping this dynamic, prompting more family offices and private wealth managers to bypass traditional VCs and invest directly into companies.

This sentiment is widely shared. "Significant wealth is being generated long before companies reach the public markets, and currently, those private markets are heavily influenced by prominent AI firms," noted one investor. "Family offices making direct allocations into AI startups are making a smart move."

This strategic shift is evident in recent deals. Arena Investors recently co-led a $230 million funding round for AI chip company Positron, an investment that secured the firm a seat on the board. According to Arena's David Stein, this reflects a conscious move from being passive investors to becoming "active participants in the capital markets."

The drive among family offices to engage is intense. Stein framed the imperative starkly: "The greatest risk today is not having any exposure to AI, rather than worrying about potential losses from your AI investments."

The data supports this outlook. In February alone, family offices completed 41 direct startup investments, almost exclusively in AI-related businesses. Notable examples include Laurene Powell Jobs's Emerson Collective investing in World Labs, Azim Premji's family office backing Runway, and Eric Schmidt's Hillspire investing in Goodfire. Research from BNY Wealth indicates that 83% of family offices view AI as a top strategic priority for the next five years, with over half already holding AI investments.

Some are taking even more hands-on approaches. A rising number of family offices are now incubating their own AI ventures, providing the initial seed capital, assuming operational responsibilities, and applying the same entrepreneurial drive that created their wealth. Jeff Bezos's role as CEO of his robotics company, which secured $6.2 billion in initial funding last year at a valuation approaching $30 billion, is a prominent example of this model.

On a smaller scale, Stein highlighted Tyson Tuttle, an Austin-based angel investor and former CEO of Silicon Labs—a company acquired by Texas Instruments for $7.5 billion. Tuttle co-founded Circuit, a startup using AI to optimize manufacturing and distribution, which raised a $30 million angel round including $5 million from his personal family office.

Not all new entrants are former founders. Arena's team hails from institutional finance, and they contend that meticulous analysis is what grants them the authority to lead investment rounds. "We are deliberate, we are a very slow 'yes,' and we frequently say 'no,'" explained Arena's Brett Schottenstein. "We absolutely invest in the resources, experts, and personnel required to verify that a company is genuine and can deliver on its promises."

For the Positron investment, this process involved collaborating with external specialists to assess the technology and also evaluating the cap table for signals. "If a firm like Arm is joining a deal, it suggests the technology has merit," Schottenstein noted. Arena was also aware that Oracle was a key customer, making Positron one of the few AI chips deployed within a major hyperscaler's infrastructure alongside Nvidia and AMD.

This selectivity defines Arena's involvement post-investment. Unlike a typical VC firm diversifying risk across a broad portfolio, Arena executes only a small number of direct deals annually, which fundamentally alters the risk profile. Their commitment is total; Positron represents their sole investment in an AI inference chip company.

"When we engage in single-asset direct deals and only complete a few each year, our stakes are extraordinarily high," Stein stated. "We are not managing for portfolio-level returns. We do not factor in failure for a single transaction. We are assuming substantial risk with concentrated client capital, alongside reputational risk for our firm. We dedicate an immense amount of time and resources. That level of commitment creates an alignment that founders truly value."
