So, the 28M U.S. small business owners are left out in the cold when it comes to getting help finding a new office for their business.With Digsy, we've built a solution that uses software automation + a network of 3,000 relocation experts to make it easy for business owners find their dream office & get the best deals on telecom/internet, office equipment & movers. That way, they can focus all their energy on growing their business, while Digsy helps them find a new home.We get paid by landlords, brokers and service providers for connecting them directly with new tenants & customers. | Venture - Series Unknown / Mar 28, 2016 | ||
