Seegrid, a Findlay company that makes vision-guided vehicles used in factories and warehouses, said it has received $12 million in additional equity to develop new products and undertake other initiatives. O’Hara-based Giant Eagle, Seegrid’s majority shareholder, provided more than half of the latest funding, according to Jeff Christensen, vice president of products and services. The rest came from new and existing shareholders Mr. Christensen declined to identify. He said the regional supermarket chain has also agreed to provide an additional $13 million on an as-needed basis. Seegrid equips forklifts and other industrial vehicles with cameras and computers that enable them to move safely to and from loading docks, warehouses, production lines and other industrial settings.
