About Zach

I help companies stop losing customers they worked hard to win.

I specialise in onboarding and customer success, building the systems and relationships that turn new customers into long-term ones. I've rebuilt onboarding programs from scratch, managed large account books, and coached CS teams to above-target results.

I work cross-functionally with product, engineering, and leadership to translate strategy and insights into actual changes, not just slide decks.

Barcelona-based, English-market, available for projects or ongoing work.
