Developer Marketing & Product-Led Growth Strategist

About

👋 Hi, I'm Emma. I'm currently a Senior Manager of Developer and Growth Marketing at Auth0, leading global strategies that drive user acquisition, engagement, and conversion. I build and scale integrated campaigns, partnerships, and content programs that accelerate adoption across a product-led growth funnel. I’ve launched joint campaigns with ecosystem leaders like Vercel and Cloudflare, directly fueling sign-ups and free-to-paid conversion.

Previously at Marqeta, I led digital strategy, driving a full CMS migration and global site launches that scaled international reach. Earlier at American Express, I focused on partnerships and growth marketing to expand customer engagement.

I’m mission-driven and passionate about creating seamless, accessible user experiences. Recognized for building and mentoring high-performing teams, I thrive in fast-paced, experiment-driven environments where growth and impact are measurable.
