The best things in life sustain themselves over time. Whether it's relationships, investing strategies, careers, or habits – if it can't go the distance, I'm not interested. I try to write about those concepts in plain English. No jargon, no fluff. Just honest insights on enduring concepts in investing and life. I've blogged on and off for the last several years and this simple site has what I consider to be my best, most enduring writing. I'll continue to update over the coming months with more content as I dig through the archives. # About Me For the past 15 years, I've been active in climate tech and sustainability. My journey's taken me through: - Finance at a Fortune 500 power generation company - Product leadership at a high-growth startup - Early-stage investing - And now, growth-stage investing. Currently, I lead Growth investing at Energize Capital. We focus on capital light solutions solving problems surrounding industrial digitization and the energy transition. # Newsletter > [!NOTE] [Subscribe to Sustainable Returns my weekly newsletter](https://kevindstevens.substack.com/) # Contact Have questions, feedback, or want to get in touch?
