Logan Grizzel

Logan is an Operating Partner at MUUS Climate Partners, where he works closely with portfolio companies to accelerate growth, scale operations, and drive impact. Drawing on a deep background in venture capital, product development, and net zero energy, he brings a pragmatic, hands-on approach to helping founders navigate the complexities of commercialization and market expansion.

Logan has decades long experience sourcing and executing climate technology investments, as well as supporting portfolio companies post-investment. Prior to MCP, he served as Partner and CTO at Blackhorn Ventures, where he invested in technologies advancing resource efficiency across the built environment, transportation, and energy sectors. During his time there, he helped grow the firm from a single fund to three, and built a portfolio of more than 60 companies.

Logan began his career in physics at Georgia Tech, developing a strong foundation in analytical problem solving. He went on to join Toyota, where he worked across electrified vehicle product planning, marketing, and strategic research, including launching a new powertrain and vehicle. He later joined Navigant (now Guidehouse) as a management consultant, advising major automotive OEMs and utilities on mobility electrification and energy efficiency programs. This breadth of experience ultimately led him to venture capital, driven by a passion for supporting mission-driven founders.

Logan’s operating perspective is grounded in years of firsthand experience working with startups and corporates alike to bring sustainable innovations to market. Based in Colorado, he recharges by spending time outdoors, mentoring early-stage entrepreneurs, and diving into audiobooks on everything from history to systems thinking.
