Delta Purna Widyangga graduated from Nanyang Technological University in Singapore in 2009 with an engineering degree in electrical and electronic engineering. He then worked as a software engineer at Accenture and as an SAP consultant at ecenta AG.
In 2011 he co-founded a digital agency in Singapore called 1.618. He stayed with it until 2017. The agency brought in revenue while Qiscus was still looking for its market.
Qiscus began in 2013 with Evan Purnama, Muhammad Md Rahim and Amin Nordin. A seed round of about $100,000 arrived in late 2014. In 2015 Nordin left and Widyangga became CEO.
The company sells a chat SDK and a multichannel customer inbox to businesses. Qiscus reached profitability in 2019, and Init6 later made a strategic investment in the company.
