As the GTM Lead at Maire, I lead our market expansion efforts. My career has moved from large corporate environments like Tesla and Mandatum to growth-stage companies like Upright Project.

I have experience of building B2B sales pipelines and managing client relationships in finance and technology. I now use the sales discipline I learned at global leaders to help growth-stage companies grow their revenue and reach new markets.
