AI product leader and entrepreneur with 10+ years building technology products from zero to acquisition. I am currently designing and deploying production agentic AI systems in healthcare (multi-LLM orchestration, RAG pipelines, voice AI, and custom tooling) as cofounder and lead AI engineer at Basilias.
I grew up and completed undergrad in Johannesburg before winning scholarships to attend NYU for grad school in philosophy. In 2016 I founded podcast technology startup Pippa, led it through Techstars, and sold it to Acast in 2019. At Acast I served as Director of Product and then VP of Strategy through and after their IPO, leading platform partnerships with Amazon, Apple, and Meta.
I spend my year between NYC, Philadelphia, and Plettenberg Bay, South Africa.

Drove strategic acquisitions and competitive disruption initiatives; developed operational efficiency frameworks for digital advertising, SaaS, and subscription products.
