Nina Vaca is the chairperson and CEO of Pinnacle Group, an IT and staffing firm based in Dallas, which has grown so fast it has made the Inc. 5000 list of fastest-growing companies thirteen times. It was named the fastest-growing woman-owned business in the United States by the Women Presidents Organization in 2015–when her company crossed a billion dollars in revenue, and again in 2018. Nina founded it 25 years ago, when she was just out of college, with just $300.
