With record amounts of investor cash flowing into private equity even as the days of cheap credit have come to an end, buyout firms are looking for an edge to make deals float. Ronald Blaylock’s newly launched GenNx360 Capital Partners is betting on its ability to turn portfolio companies around by working closely with company executives or installing its own management teams. To help out, Blaylock, founder of Blaylock & Co., a leading minority-owned investment bank, has brought in Lloyd Trotter, 62, a former vice chairman of General Electric as a general partner. Trotter was perhaps best known for creating the Trotter Matrix, a method of evaluating management performance that legendary former CEO Jack Welch once said had never failed to generate a significant improvement in performance at the company’s business units. GenNx360 will target companies in water treatment, specialty chemicals and other industries with $250 million to $1 billion in annual revenues.
