Tech Valley Communications, a Riverside Partners portfolio company that provides fiber optic data, voice and high-speed Internet services, has agreed to acquire TelJet Longhaul. The transaction includes TelJet's fiber network and colocation facility. Based in Vermont, the company provides data, Internet and colocation services to enterprise and wholesale customers in Vermont, New Hampshire and Montreal, utilizing its own fiber optic network. The acquisition will create a dense fiber network in Upstate New York and Northern New England, with more 190,000 fiber miles and nearly 1,100 lit buildings combined. Riverside Partners, a Boston-based PE firm, acquired a majority stake in Tech Valley in 2010.
