Freelancers and contractors are a rapidly growing part of the workforce. Without benefits, however, many struggle with issues like figuring out how much of their earnings to withhold for taxes and finding insurance providers.

A new startup called Zen99 wants to help contractors with a free service. Backed by Y Combinator, Zen99 lets users sign up for health insurance, track earnings and expenses, and figure out how much to save for taxes on a single dashboard. It also offers advice through online guides at Zen99 University.
