Academia asks the right questions, but I wanted to apply the answers in the real world at scale. Marble gave me everything I needed to make the transition from academic to entrepreneur.
What We Look For In Founders
Climate Motivated
You only want to work on things that are directly trying to solve climate change. It’s a singular focus for you and the only way you want to spend your time. You have some knowledge of the climate tech world and existing startups in the space.
Technically Outstanding
You are technically outstanding in a relevant domain. A PhD in a relevant field is a big plus. You must be very comfortable reviewing and assessing scientific literature and be able to ideate technically. Your technical background directly relates to the impact areas we are looking to build in, or in an area that we believe could unlock high impact climate solutions.
Drive and Determination
You are a driven individual who has always pushed themselves to achieve the best outcome they can get. You’ve worked around problems in the past. Found innovative ways to get what you needed done. And you’re determined to see things through to the end. You’ve experienced failures in your professional or personal life that you had to overcome to get to where you are today.
Convincing
You are able to explain complex topics simply. You understand the key message you need to get across. You have used successfully convinced others to collaborate with you on topics or approaches that you believe to be the most interesting.
Creativity
You look for new and unexpected approaches when you’re solving problems. You’re open to new suggestions when you’re trying to solve a hard problem and actively seek input from others. You can break down complex challenges into component parts so that you can more effectively find innovative ways to solve them. Whether it’s the latest technical paper, or established techniques from another field, you explore many routes when looking for a solution.
Ready to Build
You are convinced that starting a company is your best way to make the maximum impact on climate. You’ve thought about stepping into entrepreneurship, but haven’t felt like you can take the leap before now. You’re tired of focusing on academic goals and want to find a way to build and effect real world change, quickly.
