About KOLLAZ

KOLLAZ is an Ottawa, Ontario publisher of personal finance guides and spreadsheet tools, run by Valentin Iosif. The guides on this site answer one money question at a time, with worked numbers and named sources, and each one pairs with a spreadsheet in the Kollaz Etsy shop for readers who want the math done for them.
