The collapse in active usage of Prosus portfolio company Stack Overflow over the last three years has been nothing short of spectacular.
The repository of coding knowledge, where developers are able to get help from peers on questions, saw the number of user questions per month drop to below 3 500 in December 2025 or just under 7 000, when including deleted questions a decline of 80 from the prior year.
This level is 98 lower than its peak, reached in March 2014, according to company data. Including deleted questions, its peak was around 300 000 per month at the start of the Covid-19 pandemic.
