Brilliant innovation deserves to scale, especially when it helps the planet. But scaling that impact takes more than tech; it takes structure, clarity, and support. I work with founders building planet-positive technologies: climate solutions, biotech breakthroughs, sustainable infrastructure, and more. Often, they come to me stuck; the tech is
strong, but the business side isn’t landing.
That’s where I step in. With over 15 years of experience in cleantech, climatetech, and sustainable innovation, I’ve founded and led multiple startups from inception to international success. I bring a founder’s mindset, deep technical insight, and practical strategies to help early-stage innovation become fundable, scalable, and impactful.
I’m currently the CEO of Nexuma, a firm accelerating the commercialization of cleantech solutions for rising sea levels, carbon capture, and renewable energy.
I work alongside founders and teams to: -Fix what’s broken and identify the fastest path to traction. -Prepare for capital raises with compelling decks and clean data rooms. -Align messaging, operations, and leadership to support real growth. -Guide market entry into the US and EU with the right strategy and support.
I also lead Sealor, our nature-inspired flood prevention venture, which uses biotechnology to protect coastal cities from climate-driven disasters.
From strategic insight to hands-on execution, I help transform great tech into investable ventures, built to last.
