| Digsy | Digsy is an online platform that makes it easy for small business owners & startups to find new office space & services — free of charge.Small business owners don't have time to search for new office space & services, and while traditionally the solution would be to hire a commercial real estate agent, agents don't want torepresent small business owners (commissions are too small). 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 | http://www.getdigsy.com/ |
