Kreditech, the German startup backed by Peter Thiel, Rakuten and the IFC that creates credit ratings and provides finance to people who may not otherwise have credit histories, has raised another round of funding from one of its strategic partners. PayU, the payments company owned by Naspers that is known by some as the “PayPal of emerging markets” — its business is mainly in providing payment services to online merchants — is investing €110 million ($120 million) in Kreditech.
