Tübin­gen — The Tübin­­gen-based audio start-up Mirelo AI has raised 41 million US dollars in a seed round. The round was jointly led by renow­ned inves­tors Index Ventures and Andre­es­sen Horo­witz (a16z). Other inves­tors include Atlantic.vc and Triple­Point Capi­tal. YPOG provi­ded compre­hen­sive legal advice to Mirelo AI on the finan­cing round. 

Mirelo AI was foun­ded in Tübin­gen in 2023 and deve­lops AI models for the auto­ma­ted gene­ra­tion of sound effects for moving image appli­ca­ti­ons. The tech­no­logy aims to simplify and rede­fine the crea­tion of sounds for adver­ti­sing, games and film produc­tions. Sound effects can be gene­ra­ted, edited and auto­ma­ti­cally synchro­ni­zed on the basis of video mate­rial. The basic tech­no­logy is conside­red promi­sing for appli­ca­ti­ons in the crea­tive and media industry. 

Mirelo AI intends to use the finan­cing to grow faster, in parti­cu­lar to prepare for market entry, drive forward the further deve­lo­p­ment of its models and expand the team. In addi­tion to inter­na­tio­nal venture capi­tal inves­tors, the company is supported by renow­ned perso­na­li­ties from rese­arch and industry. 

Mirelo AI announ­ces: “Our over­ar­ching mission is to become the audio plat­form for all visual content, inclu­ding videos, games, social media and movies. We are now looking for people who want to join us in shaping this future — a future where Mirelo revo­lu­tio­ni­zes the way ever­yone works with sound and helps bring more emotion and impact to audio­vi­sual content worldwide.” 

“Mirelo AI combi­nes a highly specia­li­zed AI appli­ca­tion with a scien­ti­fic foun­da­tion. The finan­cing round crea­tes a strong basis for further scaling the tech­no­logy and taking the next growth step,” says Dr. Adrian Haase, Part­ner at YPOG.
