ABOUT

Connecting market insight with commercial execution

Originally from Argentina and now based in Paris, I have worked across B2B marketing, product management and sales in European markets. My experience spans market prioritization, product commercialization, customer negotiations and cross-functional execution.

Building Mujeres en París alongside my corporate career has also given me direct responsibility for customer acquisition, profitability and adapting a business to changing demand.

I bring customer understanding, product knowledge and commercial judgment to decisions about where and how a business should grow.
