Fast, an online commerce-focused company, yesterday announced that it would shut down. The company, which employed 450, raised $120 million (at a valuation of over $500 million) from Stripe, Index Ventures, and Addition. While the news is what it is, a more interesting piece to read is about Fast Founder Domm Holland, who, to put it mildly, has a colorful past, and those in his native Australia aren't big fans.
