About Harry

Entrepreneur and builder at heart, I work on tech and innovative projects to launch or grow ambitious initiatives: products, brands, teams or businesses.

I have co-founded several entrepreneurial projects in the consumer, real estate and tech sectors (Firsty, Amastas, Sempi...), with roles covering product, go-to-market, brand strategy, acquisition or team structuring.

My approach is impact-oriented: I work on projects to launch, relaunch or structure to move them forward concretely (positioning, MVP, UX, offer, pricing, roadmap, acquisition…).

What I know particularly well:
• Launching a project or product from A to Z
• Creating a brand and a coherent narrative
• Implementing an acquisition and growth strategy
• Organizing a team or process around a clear objective

I am comfortable with both strategic subjects and execution. I like to embark, test, iterate, improve. And I am autonomous, structured and always attentive to business issues.
