Web-based debt B2B-marketplace Firstwire has built a B2B-marketplace which decentralises and democratises the debt capital markets by using blockchain. It empowers issuers to self-arrange debt directly with investors – without the need for arranging banks or intermediaries - cutting down their issuing time from 4 weeks to 1 hour. Firstwire is built on secure technology enabling issuers and investors to transact directly and instantly with each other. Vonzu was founded by Michael Dreiner and Johannes Heidl in 2015.
