BERLIN – February 13, 2014 – Clue, the Berlin-based digital fertility startup, today announced a €500K seed round led by early stage investor Christophe Maire. Angel investor Joanne Wilson joined the round, along with New York-based Luminary Labs and previous investor Thomas Madsen-Mygdal.
The additional capital will be invested into ongoing product development of its top-rated fertility-tracking app, international localization and the recruitment of additional staff.
Clue is on the leading edge of innovation when it comes to mobile health,” Maire said. “The value for women and their physicians is obvious, and the potential for powerful data analysis is huge.”
Clue has also brought on Adam Wiggins as an advisor. Wiggins is one of the founders of Heroku, a platform for web apps acquired by in 2010. Wiggins will assist in building and scaling Clue’s engineering team and technical infrastructure necessary to support the upcoming developments.
“I’m very impressed by Clue’s team and product vision,” says Wiggins. “Reproductive health is a huge problem space which has seen hardly any innovation in the past 20 years. The potential in this market is huge, and I believe Clue has the right team, the right product, and the right timing to go very big.”
