History

Six One Commodities US LLC, known as 61C, was founded in August 2018 and established its headquarters in Stamford, Connecticut. The company was founded by Ben Sutton, who serves as Chief Executive Officer. Before founding 61C, Sutton spent more than eight years at Noble Americas and accumulated more than two decades of industry experience. His background reflects the broader pattern of independent energy merchants founded by former trading-house executives. From its founding, 61C positioned itself as an integrated global energy merchant rather than a pure trading shop. Its business model combines three activities: marketing energy commodities, optimizing energy assets, and investing in infrastructure. This integrated approach allows the company to participate across the physical and financial energy value chain. 61C expanded its geographic footprint beyond its Stamford headquarters, opening offices in Houston, Madrid, Singapore, and Zug. These locations place the company in major energy trading and financial centers: Houston for North American energy, Madrid for European and Iberian markets, Singapore for Asian markets, and Zug for European commodity trading. The company states that it is active in global energy markets and operates across a global network. In natural gas, 61C reports managing more than 3.5 billion cubic feet per day and more than 85 billion cubic feet of natural gas storage capacity. This scale positions it among the leading marketers of natural gas in North America. The company leverages analytics, market insights, logistics capabilities, and disciplined risk management to serve partners, investors, and customers. The leadership team has remained centered on its founder and a group of senior executives with functional responsibilities spanning finance, operations, trading, risk, legal, investments, and asset management. The company emphasizes that its people are the foundation of its success and that its leadership possesses deep industry expertise and a proven track record of creating value. As a private company, 61C has not pursued a public listing and does not disclose detailed financial results publicly.
