Operator. Builder. Delivering Unique Growth Solutions.
I help companies turn ambiguous opportunities into clear roadmaps, measurable tests, and repeatable commercial models, with 25 years building businesses, digital products, and revenue lines from zero.
About
I grew up in South Africa and Italy and have spent the last few decades in New York building products and launching new businesses: from enterprise innovations labs to multi-million-dollar growth and build studios.
I run V. Steward Group and Prota Studios, delivering AI-driven product development and growth marketing. I lead teams that deliver lean experiments, develop agentic product and growth solutions and ship alongside founders, product teams, and Fortune 500 executives. I work best at the front edge of new businesses: the part where the brief is half a page and the answer is somewhere out in the world.
Outside work I cook whatever is in the fridge, follow the long-suffering NY Knicks (but..Knicks in 5!) and AS Roma, and speak four languages with varying degrees of conviction.
