MUUS Climate Partners Adds Logan Grizzel as Partner

MUUS Climate Partners, a climate-focused investment firm, today announced the addition of Logan Grizzel as Partner. The former partner and CTO of Blackhorn Ventures will co-lead MUUS Climate Partners' deal execution and portfolio company support.

"Climate investing has become one of the greatest business opportunities of this generation, and perhaps the most important lever for decarbonizing the atmosphere before it is too late. Logan's extensive background in renewable technologies, in addition to his ability to develop and foster long-term relationships will aid MUUS' expansion efforts across the globe," said Michael Sonnenfeldt, Chairman, MUUS Climate Partners. "Logan's expertise as both a fund manager and in sustainable market solutions will properly position us to find deals where small amounts of capital can unlock massive opportunities to scale impactful solutions.'' 

Prior to joining MUUS Climate Partners, Grizzel worked on vehicle electrification at Toyota for most of his 10 years there, plus three years focused on transportation and energy efficiency at Navigant, before moving to Blackhorn Ventures, where he invested in opportunities that improved resource efficiency in the built environment, transportation, and energy sectors. While there he helped grow the team from one to three funds and more than 60 portfolio companies.

"Logan has been a trusted collaborator for years, and we've always been impressed by his ability to connect the dots between technology and markets, through the lens of climate impact," said Ben Wolkon, Managing Partner, MUUS Climate Partners. "His impressive track record stems from deep expertise in the sectors most relevant to us, and he's one of the rare investors that can add significant value to portfolio companies."

Grizzel will be based out of Boulder, Colorado. MUUS Climate Partners is headquartered in New York.

"I'm incredibly grateful to join MUUS Climate Partners. I have known the partners and founder for years, and they have successfully built an exceptional organization that delivers superior returns. I look forward to working alongside a world-class team positioned for significant growth and long-term success," said Grizzel.
