Jason Jacobs built his climate investing platform by first becoming a leading podcaster through My Climate Journey, conducting hundreds of conversations with climate leaders that became his deal-flow engine and gave him unusually broad cross-sector pattern recognition before launching MCJ Collective. He came into climate investing after successfully founding and exiting Runkeeper, a mobile fitness app acquired by ASICS, bringing a distinct product and community lens that's less common among climate investors who typically come from energy, policy, or finance backgrounds.

• Deep interest in the intersection of sports and education, specifically within the niche of ice hockey player development. He actively produces content for his own project, Puck Academy, where he interviews coaches and experts about teaching "hockey IQ" and the nuances of coaching different levels from college to the pros.
• A focus on the "builder" mindset and the "ship early" philosophy. He frequently shares his own experiences prototyping new ideas, such as a tool for teaching sports strategy, and believes that if you aren't embarrassed by your first version, you waited too long to launch.
• Active experimentation with Artificial Intelligence, particularly regarding how LLMs interact with human ideas. He has expressed a desire for AI that pushes back and challenges his thinking rather than just agreeing with him, and he even tested creating a digital profile trained on his own writing to see how well it could mimic his responses.
• Observations on modern parenting and the shift in childhood dynamics. He often contrasts the unstructured free time he had growing up with the highly scheduled lives of kids today, while also sharing relatable anecdotes about raising a teenage son, such as finding a fan message his son sent to a professional athlete.
• Appreciation for soft skills and professional courtesy in business. He values the ability to "close the loop" with people who aren't a good fit for a deal or role, emphasizing that letting people down gently is a crucial part of building a long-term brand.
