What is Lauren Leto's net worth? Lauren Leto's net worth is $10 million dollars. Lauren Leto was a student at Michigan State University, when she began posting texts from an ex-boyfriend to a site called, "Texts from Last Night". The site became a hit almost instantly, striking a cord with a number of people, and has since grown into a multi-million dollar business. The site also inspired a book, which was published under the same name in January 2010, and a television series is being developed based on the texts. In addition to her work on "Texts from Last Night", she also wrote the book, "Judging a Book by Its Lover", which will be published by Harper Perennial in the fall of 2012. Additionally, she co-founded Bntr, a social media site that recently made headlines when its largest investor, Spark, pulled out of the deal at the 11th hour, and refused to pay a "break-up" fee. Spark has offered no explanation, and their actions have rocked the start-up world, which is largely built on investor trust.
