About BigSur Energy

BigSur Energy is an Argentinian EnergyTech company that converts stranded or vented natural gas from oil fields into low-cost electricity for off-grid, modular data centers. The company’s business model is centered on energy arbitrage, installing its data centers directly at oil wells to harness otherwise wasted gas. This approach provides an independent power source for high-performance computing tasks required for AI and Bitcoin mining. By monetizing previously unmonetized energy reserves, the company offers new revenue streams for oil and gas producers and reduces methane flaring.

The company was co-founded by Ariel Perelman, a serial tech entrepreneur with a background in cloud development, and Bernardo Cabral Nonna, who has two decades of experience in the oil and gas industry. Their leadership team also includes CFO Claudia Perez, who has IPO experience, and General Manager Maria Emilia Cabral Nonna.

BigSur Energy has undergone several funding rounds, including a $4.7 million seed round in December 2025 and a Series A in the summer of 2025. In March 2026, the company closed an $11.5 million Series B funding round, which brought its total capital raised to over $20 million and its valuation to over $90 million. The Series B was supported by existing investors, including the Braun Saint family. BigSur Energy operates 14 sites in Texas and Louisiana and plans to use the funds to expand its operations in the United States. The company is also preparing to enter the Argentinian market by 2026 through an asset-light partnership model, where local oil companies finance the infrastructure while BigSur provides the technology and operational management. The company has stated its goal of going public with an IPO in the United States by early 2028.
