MCJ is a seed fund manager for industrial transformation and infrastructure resilience. We discover and invest in startups rewriting industries to be cleaner, more profitable and more resilient.
We successfully closed our second fund at MCJ, MCJ 2023, bringing in $80.6M in total capital commitments, and pushing our total assets under management to over $115M. As with our earlier funds, this capital is dedicated to backing startups driving the transition of energy and industry and solving the inevitable impacts of climate change. The need for greater climate resilience drives us to seek solutions that make our infrastructure stronger and our world safer. Conversely, humanity will unlikely embrace austerity in the face of climate change (our societal drive for ever greater computing needs are but one example of this) and so we are continuously seeking clean solutions to meet an increasing demand for power. These dual themes of energy transition and climate resilience have been driving much of our recent investment activity.
We strengthen our investments through the MCJ Collective — a vetted member network that connects talented tech and industrial leaders with our portfolio and with one another. Our media platform, including the Inevitable podcast and MCJ Newsletter spotlight key perspectives critical to our portfolio and the transition at large, reaching tens of thousands of professionals multiple times per week. And finally our corporate partnerships, which span industries and provide unique value to portfolio companies, sector expertise for due diligence, and capital for future funds.
Investment Example
Base Power provides reliable home energy solutions powered by distributed batteries, enhancing grid resilience and lowering costs. Co-founders Zach Dell (CEO) and Justin Lopas (CTO) bring expertise in venture-backed startups, energy systems, and distributed storage to build a smarter, more resilient grid. MCJ first connected with Base Power through an LP introduction. In April 2024, MCJ invested $400K in the company’s Series A, led by Valor Equity Partners. After its initial investment, MCJ immediately leveraged its network to strengthen Base Power's team, directly contributing to three key hires: Mechanical Engineer, GTM, and an intern. MCJ further elevated their industry profile by featuring Zach Dell in a live Startup Series podcast during Houston's inaugural Energy & Climate Startup Week. Base Power exemplifies MCJ’s approach—investing in early companies and providing the connections, expertise, and opportunities to accelerate impact.
