Founder

Mark Tyndall

Mark Tyndall founded Certulo because he believes much of the work of decarbonising the economy will be done by ordinary businesses, and that many of their projects will need a loan.

Certulo is being built to help owners get the paperwork behind a project in order before they take it to their bank and, where Certulo holds a mapping, to show which criteria in Version 1 of the Australian Sustainable Finance Taxonomy an asset can be matched against. Lenders can refer to the Taxonomy for some of these projects, and the lender decides whether, and how, to use it.

Mark was a solicitor at Herbert Smith Freehills from 2015 to 2019, working on regulatory investigations in financial services and energy. Since 2020 he has worked in technology company strategy, sales and delivery. He holds a Juris Doctor from the University of Melbourne.
