Sesame Sustainability, a Boston-based climate technology startup developing software for industrial decarbonization, has raised $2.4 million in seed funding to accelerate the development and commercialization of its engineering-grade platform that helps organizations evaluate and optimize low-carbon infrastructure investments. The financing marks an important milestone for the MIT spinout as heavy industries increasingly seek practical tools to model decarbonization pathways while balancing cost, operational performance, and emissions reduction.

The seed round was co-led by Flybridge and Powerhouse Ventures. The investment will enable Sesame Sustainability to expand its software platform, grow its engineering and commercial teams, and accelerate deployment among industrial companies seeking data-driven approaches to decarbonization planning.

Founded by Jim Owens and Paul Sizaire, Sesame Sustainability was created to address one of the most complex challenges facing heavy industry: identifying economically viable pathways to reduce carbon emissions across large-scale industrial operations. While many organizations have established ambitious climate targets, evaluating the technical and financial implications of competing decarbonization strategies often requires extensive engineering analysis, fragmented data, and months of specialized consulting work. Sesame aims to simplify this process through an integrated software platform that delivers engineering-grade analysis in a fraction of the time.

The company’s platform combines economic, environmental, and systems analysis capabilities to evaluate industrial decarbonization projects across multiple scenarios. Users can compare technologies, estimate capital and operating costs, model emissions reductions, and assess infrastructure requirements through an intuitive interface designed for engineers, executives, project developers, and sustainability professionals alike. Rather than relying on disconnected spreadsheets or custom-built models, organizations can perform standardized analyses that support more informed investment decisions.

According to the company, the platform enables users to conduct rapid scenario analysis across a wide range of industrial applications, including hydrogen production, carbon capture, renewable energy integration, fuel switching, electrification, and other decarbonization initiatives. By providing consistent methodologies across different technology pathways, Sesame seeks to improve decision-making while reducing uncertainty surrounding major capital investments.

The newly raised funding will primarily support continued product development as Sesame expands the functionality of its software platform. The company also plans to enhance user experience, strengthen simulation capabilities, and broaden commercial adoption among industrial customers seeking comprehensive planning tools for net-zero initiatives.

Sesame Sustainability originated from research conducted at the Massachusetts Institute of Technology, where its founders developed advanced modeling techniques capable of evaluating complex industrial energy systems. The technology has already been applied to projects involving organizations such as the U.S. Department of Energy, MIT, and Virginia Tech, demonstrating its ability to analyze infrastructure decisions involving multiple technical, economic, and environmental variables. The transition from academic research to commercial software enables the company to make these analytical capabilities available to a much broader range of industrial organizations.

Chief Executive Officer Jim Owens has emphasized that industrial decarbonization requires more than ambitious sustainability goals—it also demands rigorous engineering analysis that helps organizations understand the financial and operational consequences of different investment strategies. The company’s software is intended to reduce the time required to evaluate major infrastructure projects while providing stakeholders with greater confidence in their decisions.

Investor interest reflects the growing demand for digital tools that support industrial decarbonization. As governments and corporations continue committing to long-term emissions reduction targets, companies operating energy-intensive assets increasingly require software capable of evaluating competing technologies, optimizing investment decisions, and measuring environmental impact before committing billions of dollars to new infrastructure.

The participation of Flybridge and Powerhouse Ventures also highlights broader venture capital interest in climate software companies addressing industrial emissions. Rather than focusing solely on developing new hardware technologies, investors are increasingly supporting software platforms that help existing industries implement decarbonization strategies more efficiently through better planning, modeling, and decision support.

Sesame’s platform is designed to serve a broad range of industries, including energy, chemicals, manufacturing, transportation, and other sectors where infrastructure investments involve significant financial commitments and long operating lifecycles. By allowing users to compare multiple pathways using standardized methodologies, the company aims to improve both the speed and quality of industrial climate planning.

With fresh seed funding and backing from experienced climate technology investors, Sesame Sustainability is positioned to expand its industrial decarbonization platform as organizations accelerate investments in cleaner infrastructure. By combining engineering-grade simulation, economic analysis, and environmental modeling within a single software platform, the company aims to help industrial businesses make more informed decisions while advancing the transition toward lower-carbon operations.
