We became cash flow positive in 2016 and profitable in 2017. In 2020 our CEO Patrick at the time started on a path to figure out how we could buy out our series A investors. When we were acquired in 2022 by Ziff Davis we were fully employee and founder owned.
Cash-flow positive 2016, profitable 2017, bought back Series A in 2020, exited 2022 fully employee-owned
Lose It! launched in 2008, took a small Series A for walking-around money, added subscriptions in 2012, hit profitability in 2017, used cash flow to repurchase the Series A in 2020, and exited to Ziff Davis in 2022 as a fully employee-and-founder-owned company.
