Clark Lewis

Paul Touradji closed Touradji Capital Management in 2011 after a run that saw the fund's assets under management peak at roughly $3.5 billion and then decline amid margin calls in base metals and a contentious divorce from his wife, who was also the firm's general counsel. The closure represented one of the more abrupt Tiger Cub unwinds of the post-2008 period, and the remaining capital was consolidated into Clark Lewis, which had been established three years earlier as a parallel family office vehicle.

The office takes a physically rooted approach: direct acquisitions of ranchland, farms, and water rights form the core equity book, supplemented by opportunistic commitments to energy infrastructure and select external commodity hedge fund managers. Touradji's training at Tiger—where he specialized in copper, crude oil, and base metals—informs an insistence on understanding the physical supply chain rather than relying solely on financial derivatives. This strategy is executed primarily through direct deals rather than fund commitments.

Clark Lewis is structured as a single-family office for Paul Touradji but has been reported to co-invest alongside a small circle of industrialist families on large-scale timber, agricultural, and energy deals. The office does not openly market investment services or accept unsolicited capital, maintaining the posture of a proprietary investor that occasionally syndicates deals to trusted co-investors.

The firm is named after the Clark and Lewis mountain ranges in Montana, near the Yellowstone River. Touradji has personal and professional ties to the region, and the name signals the office's enduring focus on the American West as both a geographic investment thesis and an operating base for its ranchland and agricultural portfolio.

The office does not publicly enumerate investment restrictions, but Touradji's career track and the firm's observable deal flow indicate a low appetite for late-stage technology, venture capital, and growth equity. The portfolio is overwhelmingly weighted toward tangible assets and hard commodities, with no known commitment to software, internet, or consumer-focused venture funds.

Paul Touradji serves as the sole founder and principal investment decision-maker. Unlike some family offices that transition to a professional CIO or investment committee over time, Clark Lewis remains a concentrated expression of Touradji's personal investment framework—an owner-operator model where the founder directly sources, negotiates, and oversees the portfolio's largest holdings.

Paul Touradji is a direct Tiger Cub, having worked for Julian Robertson at Tiger Management from 1996 until 2000 as a commodities analyst before leaving to launch Touradji Capital. The Tiger network is typically associated with long-short equity managers, but Touradji's office represents a divergent path: abandoning the fund structure entirely in favor of a permanent-capital family office built around the physical resource investing skills he developed at Tiger.
