Sydney Angels portfolio company Atomo Diagnostics listed on the ASX (ASX:AT1) on 16 April. A few far sighted Sydney Angels members invested in Atomo starting back in 2010 - and their investment has been worth it - with the closing price on the first day representing more than 10x return on investment (based on the closing price of $0.39). Congratulations to Atomo and its investors. Atomo is a global leader in pathology on a stick diagnostic kits and has achieved remarkable success, especially with its HIV test in developing countries without a network of pathology labs. One of its key investors is the Bill & Melinda Gates Foundation.
