About us

Schlafender Hase develops TVT, a content verification platform for regulated industries. TVT verifies text, images, barcodes and spelling across different file formats, languages and layouts, ensuring error-free documentation before you print or publish. Today, more than 440 companies in pharma, medical devices, FMCG/CPG and crop science rely on it.

Founded in Frankfurt in 2001 (our name – German for "sleeping hare" – started out as an internal code name), we are now a team of around 40 people, headquartered in Frankfurt am Main with an office in Montréal, Canada. With Maguar Capital joining as a new investor in 2026, we have entered our next phase of growth – and that is where you come in.
