Bill Jula isn't planning to become another Mark Zuckerberg. His Sarasota-based Fast Pitch is a B-to-B networking/marketing site, not a social one like Zuckerberg's Facebook. Jula co-founded Fast Pitch in 2006 and says membership has reached "hundreds of thousands," including 20% outside of the United States, although he won't reveal the exact number of users. "We're definitely a nice strong niche," he says.
