Sergio Tache

Founder & CEO Dossier Perfumes

Sergio Tache is the Founder and CEO of Dossier, a digitally-native fragrance house that makes luxury fragrances without excess markups and pretentious marketing. He launched Dossier in 2019 after learning how the cost of your designer fragrances isn’t at all related to the product’s quality.

With Dossier, Sergio helps to set a new standard within the industry––removing pretenses, like the designer brand name tax and use of elitist marketing practices, namely celebrity endorsements, that drive up luxury fragrance prices. Dossier aims to help customers focus on a product’s quality, not a desired perception. All Dossier products are made in France, just without the price gouging.

Sergio launched the company with its now-hero collection of Dossier Impressions, a collection of designer-inspired fragrances available for 70-85% less. With their success, he leveraged the company’s learning from experience to develop Dossier Originals (a collection of in-house exclusive fragrances) and Dossier Home (a line of room diffusers and candles with scents from customer-favorite Impressions). As of 2024, Tache has successfully helped the company expand outside of the U.S. to Mexico, Canada, and Australia and acquired Amazon and Walmart as retail partners.

Before building Dossier, Tache held several CEO roles within the digitally-native beauty space––working within the haircare and skincare industries after leaving the finance industry.

Sergio holds an MBA in Finance from the Wharton School of Business at the University of Pennsylvania with his Master’s and Bachelor’s degree from Solvay Brussels School of Economics and Management (in Belgium, where he grew up).
