Growth Inflection was founded after two decades of scaling early and growth-stage companies from seed to Series B, mainly in ad tech, AI, and climate tech. Recognizing common challenges, we decided to use our expertise and networks to help founders streamline and accelerate go-to-market, operations, and leadership. In climate tech, sales cycles and budgets are often complex and policy-driven. Drawing on both successes and lessons learned, our mission is to accelerate growth and reduce key stressors for founders.

„We identify your next inflection point, and work with you to achieve it.“

Go-To-Market, Marketing, Operations, Customer Centric, bringing businesses to US and EU

I help bold companies grow—fast, smart, and for the long haul – I’ve spent 2 decades in the trenches — building brands, scaling startups, and steering businesses through stormy markets and soaring highs in USA and EMEA. I’ve helped early-stage teams find their footing and late-stage companies unlock their next leap. I speak the language of sales, marketing, eCommerce, and SaaS — and I know what turns a pitch into a revenue pipeline. For the past 10 years I’ve helped ambitious founders grow. Not with jargon. Not with hype. With strategy, storytelling, and execution that works. Because growth isn’t luck. It’s a system. And I know how to build it.

My whole career has been working in startups, building out go to market teams from the ground up. I’ve navigated through bootstrapping, scaling with VC funding and optimizing for profitability. My focus is on moving our world toward a cleaner future. Unlocking repeatable growth in the complex climate tech market is where I thrive. Having worked in the US, Europe, Africa and Asia, I gravitate toward global opportunities.
