This Week in MCJ (3/27/21)

Hi all,

We had a great Town Hall this week, where we shared some of the things we are thinking about and excited about, and got a lot of great feedback from the MCJ’ers who attended. The big theme for us heading into Q2 is making things better for the people who are already here. That includes both existing MCJ members, and the MCJ Collective portfolio companies we’ve already backed. We are big believers that this is not only the best way to keep the existing community strong, but also the best way to grow!

There are a whole host of things we have planned to start to streamline and improve the MCJ experience. Some of them are little, and more incremental improvements to reduce friction and increase delight. And some are bigger moves, that should introduce some great new capabilities to the platform! There is a lot of work to be done, and it won’t be done overnight. But we are deeply committed to continuing down this path, and plan to stay focused, bring in additional resources, and expand our pace of development. Cliche to say, but we truly are just getting warmed up.

Thank you for joining us on this journey!

🎙The Week’s Episodes

Jason had a lively conversation with the New York City Comptroller, Scott Stringer, on Episode 149 of the MCJ pod about his decision recently to divest NYC pension funds from $4B of fossil fuels.

Later in the week, Jason had a chance to catch up with Andy Towne on a great episode of our Climate Careers podcast. Andy is a Founding Partner and CEO of Hobbs & Towne, an executive search firm that has been working in climate tech since well before it was called climate tech. Andy has great insight into what is happening in the trenches of climate tech innovation, and how this time is similar or different to the last wave.

During Wednesday’s MCJ Live show on Clubhouse, Jason was joined by Kelly Hering (Charm Industrial), Maria Carolina Fujihara (SINAI), Chris Tolles (Yard Stick), and Shashank Samala (Heirloom) to discuss Climate Tech Startups: Lesson from the Trenches.
