Let’s say a full 50% of Canva’s customers eventually churn because of this. They’re raising prices 3x, so they’d still make 1.5x their previous revenue. And they’d make even more profit, because their customer support costs have been cut roughly in half.
Meanwhile, the 50% of customers who dropped are now on the market for a new design tool — and a big hole has just opened in the low end of the market. So it’s good for competition, too!
Of course, if 80% of Canva’s customers leave, that’s bad for them. It’s a gamble! But in general, increasing prices by Nx in hopes that you’ll retain at least (1/N)x customers is a totally reasonable strategy.
