Chestnote, an Antwerp, Belgium-based time-defying app, raised €650k in funding.
Backers included Nova Reperta Holding, imec.istart and Martin Raeymakers.
The company intends to use the funds to grow operations and expand into Europe and globally.
Founded in 2015 by Tom Le Clef and Peter Wellens, Chestnote allows users to create a message, choose when and where messages unlock, send to friends and connect to channels.
The app is available for free download for iOS and Android.
