Starting at research, through ideation and validation to launch to finally product-market fit, and from PMF to global scale. The strategy and execution changes. The principles not so much.
Generalist depth.
Not an oxymoron. Research, product strategy, operations, data, growth, measurement, growth. I work in systems and you will get the whole package, even if it goes beyond the JD.
A decade at Meta took me from sales to product, from machine learning, to business integrity, to commerce, to messaging, to VR, to wearables. I led major product launches: GDPR readiness, Political Ads, the EU Parliament Elections, and the first ML model for Commerce Solutions (which scaled to a $2B+ run rate). I was part of the first wave of WhatsApp exploration on wearables (do you remember Rayban Stories?) and emerging tech (metaverse explorations and beyond), managing teams and budgets along the way. Earlier: product marketing for advertisers in 128 countries across EMEA. Since leaving, I've run a portfolio: product consulting (including back at Meta on SMB Commerce and GenAI video), fractional/NED roles for startups and NGOs, and teaching AI applications at the London School of Public Relations. I also build. Pulp (redefining cinema), QueSitio (voice-built websites for LatAm entrepreneurs), Its A Jug (climbing safety), Mog (consumer) and Squared Coaching (a passion venture where every coaching engagement funds one for someone starting out in their careers). I am now building and advising, while scoping my next full-time role. Always happy to connect.
