Germany-headquartered mobile banking startup N26 has raised a whopping $300 million in a series D round of funding led by Insight Venture Partners, with participation from Singaporean sovereign wealth fund GIC and a handful of existing investors. This raise officially elevates N26 into the much-coveted unicorn club, bestowing upon it a valuation of $2.7 billion. Founded in 2013 as Number26, the Berlin-based fintech startup rebranded as N26 in 2016 just as it obtained its own banking license.
