Zac Cohan

Zac Cohan is the Sydney-born co-founder of Acqualia Software. He has been making Mac apps for more than 20 years and won an Apple Design Award in 2007. In 2005 he came up with the idea for a notepad-based calculator, with a column that works out an answer for each line as you type. This became Soulver, which he has kept improving ever since and which is now in its fourth major version. Zac loves the Mac, tech history and great productivity tools. He's working on new interfaces that push plain-text thinking tools further. He lives in southern Turkey, by the Mediterranean, with his wife.
