Alex Wiltschko
Alex Wiltschko is the founder and CEO of Osmo, a company teaching computers to read and write smell. An olfactory neuroscientist who spent roughly 18 years studying scent, he led the team at Google Brain that built an AI model predicting how a molecule smells from its chemical structure - work published in Science in 2023 as the Principal Odor Map. Osmo spun out of Google in 2022, and in 2024 it pulled off 'scent teleportation,' digitally capturing a fresh-cut summer plum and reprinting its smell in another room. In February 2026 the company raised a $70 million Series B led by Two Sigma Ventures.
Osmo
Osmo is a digital olfaction company teaching computers to smell. Spun out of Google Brain in 2022 by neuroscientist Alex Wiltschko, it built an AI 'Principal Odor Map' that predicts how a molecule smells from its chemical structure, then uses that model to design new aroma ingredients and digitize real-world scents. In 2024 it became the first to 'teleport' a smell - capturing a fresh plum and recreating it with no human in the loop. Its platform, Olfactory Intelligence, now powers Generation, the world's first AI-driven fragrance house working with roughly 100 beauty and consumer brands.
