Climate CEOs: Scaling Startups

William McDonough is one of the world's most influential sustainable design thinkers. His book, Cradle to Cradle, kick-started my career path. And I enjoyed working with him in environmental private equity for many years.Bill has advised companies, governments, and cities on regenerative design for decades and has won awards such as the Presidential Award for Sustainable Development, the National Design Award, the Presidential Green Chemistry Challenge Award, and the title of "Hero for the Planet" from Time magazine.Climate tech often focuses on reducing harm. Bill McDonough argues that's the wrong starting point. In this episode, we explore how design, economics, nature, and human intention can create systems that are not merely less bad but genuinely beneficial.🌎 Sample topics we discussed:Climate tech needs a better story – Many environmental challenges result from default outcomes, not intentional design. Leaders should actively choose the future they want to create rather than inherit existing systems.Nature before artificial intelligence – AI can optimize almost anything, but first, we should ask what nature would do. Bill shared examples ranging from local sourcing to designing buildings and infrastructure around natural conditions.End of use, not end of life – Products, materials, and buildings should be designed for their next use. The goal is continuous value creation rather than disposal.Turning liabilities into assets – From desert sand and desalination brine to district heating infrastructure and green roofs, some of the best climate solutions emerge when waste streams become valuable inputs.Why CFOs belong in the design room – Climate solutions succeed faster when economics are considered from the beginning. Bill advocates net-positive thinking, practical implementation, and early involvement of financial leaders in the design process.--1️⃣ Join our confidential CEO community.Private CEO group for VC/PE-backed climate tech founders navigating capital, strategy, and scale.

Aalo Atomics is developing modular nuclear power plants designed for factory production. They seek to make nuclear energy scalable enough to support AI infrastructure, industrial heat, desalination, and synthetic fuels.Matt Loszak, founder and CEO of Aalo Atomics, discusses how his team is moving from software to nuclear, scaling from 2 to 165 employees in three years, raising $300M+, and pursuing a vision of abundant energy for AI, industry, and beyond.Prior to returning to his nuclear engineering roots, he founded Humi, a payroll and HR software company that grew to process roughly $10 billion in payroll.Here's what we discussed:Project to product – Why nuclear's biggest opportunity may be moving from custom megaprojects to mass-manufactured energy systems.Designing around logistics – The team constrained reactor size to what can be shipped on a truck, enabling factory production and modular deployment.Speed as a competitive advantage – Going from company formation to first reactor in under three years while scaling to 165 employees.The economics of abundance – Why sub-10¢/kWh is a critical milestone and how 3¢/kWh could fundamentally reshape global industry.Building the nuclear talent stack – Recruiting leaders from SpaceX, Tesla, Bloom Energy, and advanced reactor programs to accelerate execution.--1️⃣ Join our confidential CEO community.Private CEO group for VC/PE-backed climate tech founders navigating capital, strategy, and scale.
