Can your personality traits and background predict the success of your company? Startup Predictor, a computer program from YouNoodle, values companies by asking up to 100 personal questions of their founders -- relationships, work habits, salary history and so forth. About 6,000 entrepreneurs have already tried the free program, but venture capitalists remain skeptical. "If this worked, VCs would use personality tests and resumés," says the co-founder of Venture Hacks, a Web site for entrepreneurs seeking capital. "We can't measure an entrepreneur's spirit or determination online."
