Most people take one internship and call it experience. Between 2012 and 2015, while finishing an NYU business degree, she took ten. A newsroom, a cable network, a music magazine, two denim and apparel houses, a beauty brand, a research firm.
Before she was ever paid to explain a company, she had watched ten of them try to explain themselves.
That is the unglamorous part nobody puts on a slide, and it is exactly where the pattern recognition came from. Different industries, same failure: the story inside the building never matched the story that left it.
She started at Young & Rubicam as an apprentice and left as an associate in corporate communications, running social and digital for a network of more than 180 offices. She rebuilt the content for the yr.com relaunch, wrote the agency's global blog, and grew organic reach 800% in seventeen months.
Then McCann new business, which is the purest form of selling there is: you get one room, one hour, and no second chance. TJX, Pernod Ricard, Lockheed Martin and Lane Bryant came out of those rooms. She also organised the first Time's Up: Advertising event in New York.
Pitching teaches you something quota never does: how to make a stranger believe you in sixty minutes, with no product to demo.
Then Wondersauce, running pitches directly with the CEO and founders, winning UrbanStems, Boll & Branch, Nutrafol and The Trade Desk.
Barcelona, and a different kind of sale. At Criteo she averaged 167% of target in 2020, selling performance marketing to ecommerce brands. At Autodesk she carried AutoCAD, Revit and BIM 360 into technical evaluations with two to six month cycles and rooms full of engineers.
Then Deel, joining during hypergrowth and helping scale the UK and Ireland motion while the company ran toward a $12B valuation and past $100M ARR. She finished at 268% of quota. Then Red Points, where enterprise brand protection meant building the business case with legal, ecommerce and marketing in the same room.
Advertising taught her to sell a story. Enterprise software taught her to sell a system that has to still be working in eighteen months.
Eight AI certifications, six from Anthropic Academy and two from Google, every one independently verifiable. Behind them: three live sites, twenty open-source MCP servers, and a catalogue of installed Claude systems running in real businesses.
The throughline finally makes sense here. Fourteen years of watching companies fail to say what they do, then selling for them, then selling the software that runs them. The work now is building the thing that does it automatically, in the owner's own voice.
She is not an engineer who learned sales, or a seller who watched a tutorial. She closed for a living, and now she builds the thing that closes.
Six Anthropic Academy and two Google. Nothing appears here without a working verification URL issued by the awarding body. Click any card.
Bachelor of Arts, Business and Integrated Marketing Communications, through Gallatin, NYU's school for students who design their own degree rather than pick one off a shelf. The ten internships ran alongside it, which is why the degree and the first agency job arrived at roughly the same time. Also interviewed live on NBC on the Holocaust Impact Theater's 2012 production, Xenophobia.
Swiss and American citizen, based between Barcelona and Miami. Client work runs across EMEA and North America.
