Ethan Nelson is a founder and AI systems builder with 11 years of experience applying high-performance computing instincts from atmospheric science to practical AI-led growth and marketing. Based in Boulder, he has launched and scaled AI service products that drove recurring revenue and audience growth—building GTM strategies, AI outbound campaigns, and content systems that reached 100k+ monthly views. He combines full-stack engineering chops (notably contributions to the Humanitarian OpenStreetMap Tasking Manager front- and back-end) with hands-on prompt engineering and automation to turn content into measurable funnels and email pipelines. His background in atmospheric and oceanic science informs a data-first, systems-oriented approach to productizing AI for mid-market tech companies. Ethan is equally comfortable shipping code, designing marketing infrastructure, and teaching others how to replicate scalable AI workflows. A less obvious strength: he repeatedly translates complex technical domains into high-volume creator and community growth systems that scale predictably.
Designed and built for Humanitarian OpenStreetMap Team collaborative emergency/disaster mapping, the OSM Tasking Manager 2.0 divides an area into individual squares that can be rapidly mapped by thousands of volunteers.
