Hi there — thanks for checking out Entrix.
I’m Martim, leading Sales for Iberia (Spain & Portugal). I joined in April, and we’re now building and scaling the market from the ground up.
My background is in renewables across business development, growth, sales, and M&A, with experience at OX2, Ventient Energy (now rebranded Nadara), and Vestas. Outside work I spend a lot of time with my family, I am a big football fan and love travelling. I am Portuguese and living in Madrid for a long time.
We’re at an early stage here — which means real ownership, fast pace, and the chance to shape something meaningful from day one. It’s ambitious, hands-on, and definitely not “business as usual.”
If you’re excited by building, moving fast, and having real impact, we’d love to hear from you.
Martim
Sales Director - Iberia
