comdirect started in 1994 in Quickborn, near Hamburg, as the direct bank of Commerzbank. In November 2020 Comdirect Bank AG was legally merged into Commerzbank AG, and comdirect has run as a Commerzbank brand ever since. Contracts are therefore with Commerzbank AG, one of Germany's largest banks.
The product range is that of a full bank rather than a trading app: the comdirect Depot (securities account) and a cheaper Pure Depot, the Girokonto current account, Tagesgeld savings, a Junior Depot for children, cominvest managed portfolios and savings plans on shares, ETFs and funds. In the depot you can trade shares, ETFs, funds, bonds, certificates and listed derivatives on German exchanges, through direct trading partners and on foreign exchanges.
