Jessica Alba – $350 Million

Jessica Alba’s acting career started when she was 13 but it wasn’t until her lead role in the cyberpunk TV series Dark Angel that she rose to prominence. She made her big-screen debut in 2003 on Honey and went on to appear in numerous box office hits like the Fantastic Four series of movies. In 2012, she co-founded a non-toxic household goods startup called The Honest Company alongside her friend, Chris Gavigan. As of 2014, the company’s worth was $1 billion and its success contributed to a chunk of Alba’s $350-million wealth. Alba and Gavigan have continued growing the business and in 2015, they launched a collection of skin care products under Honest Beauty.
