Ostium homepage: the headline “The site that brings in your owners” over the living room of a holiday rental opening onto pines and the ocean

Ostium builds the websites of short-term rental managers: the property catalogue, booking wired into the software they already run, and the page that goes after owner mandates. Agency site designed and built in Next.js, in French and English, around a revenue-per-mandate calculator.
