Brian O'Kelley

Brian O'Kelley personally leads all investment decisions. He is the principal and founder, drawing on his experience building and scaling AppNexus. The office does not disclose a formal investment committee (per public record).

O'Kelley leverages his network from AppNexus and his ongoing board and advisory roles in the ad-tech and data ecosystem. Many deals come through direct founder relationships and industry introductions rather than a formal intermediary process (per O'Kelley's public statements).

It is structured as a single-family office. O'Kelley invests his personal capital from the AppNexus liquidity event. The office does not raise external capital or manage third-party funds, though it may co-invest alongside other early-stage investors (per public record).

The firm is focused on seed and Series A rounds. It seeks to invest early in technology companies where O'Kelley's domain expertise can provide strategic guidance. Later-stage or growth equity investments are not part of its stated strategy (per public record).

The firm has not publicly disclosed any explicit avoidance sectors. Based on its known focus areas, it does not appear to target biotech, hardtech, real estate, or healthcare services, but no formal exclusions have been stated (per public record).

The wealth originates from the sale of AppNexus, a digital advertising exchange co-founded by Brian O'Kelley, to AT&T in 2018 for $1.6B. O'Kelley served as CEO through the acquisition and later as an advisor, generating liquidity that formed the family office's capital base (per public filings and media reports).

The firm appears to primarily make direct investments in startups. There is no public evidence of fund-of-funds or GP commitments. However, it may co-invest with venture capital firms in early-stage rounds (per public record).
