Simon de Carlan
Founder and art director of Sonho Agency
Simon de Carlan founded Sonho in 2023, in Paris. He designs and codes the agency's Shopify stores and websites, and works on their visibility on Google and in AI engines.
What he does at Sonho
Simon is the brands' point of contact from the first call to launch. He takes the brief, designs the pages, codes them and trains the client's team so they can edit their site on their own.
Sonho brings four trades under one roof: Shopify stores, websites, brand identities, and search visibility on Google and in AI engines. A site goes live in six weeks on average.
