Lightyear Network Solutions
Founded in 1993 as UniDial, Lightyear experienced financial difficulties from its inception. On April 1, 2013, after posting a net loss of $2.3 million for 2012, the company announced it was looking for a buyer. That buyer turned out to be Birch Communications which subsequently dissolved and liquidated the company. (And, as mentioned before, Birch was acquired by Fusion Connect in 2018.)
