Who Are We?

At Musimap we leverage the latest in machine learning and deep learning methods, empowered by a database of more than 1 million tracks labelled manually in a large-scale effort by music experts. We perform cloud-based big data analyses from the global catalog of music (35+ million tracks) to extract information about genres, sub-styles, vocal gender, moods and dozens of other parameters. Musimap is a B2B company and our customers include music streaming companies, labels, production music companies and advertising & branding companies - such as BMG, Warner Music, Universal Music, UnMute, and others. We also partner with IRCAM, BMAT, SoundtrackYourBrand and other institutions in the European H2020 project FuturePulse.

We have built fully Deep Learning based music search and tagging products.
