Patrick Stewart built Pepperweed Consulting into one of Pittsburgh's fastest-growing companies with $12 million sales in four years before selling the Sewickley-based IT consulting firm to Avnet Inc. in July 2012. Now Stewart and a handful of Pepperweed/Avnet alums have started Innovu LLC, aimed at helping self-insuring companies navigate the complex health care environment to deliver efficient and cost-effective benefits plans.
