“Last year, our mighty donor base – representing approximately 300,000 daily users – contributed a total of $6,442,704 in donations to the Thunderbird project.”
Thunderbird took in $6.4 million in 2022 and spent $3.6 million. Donations are more than 99.9% of revenue. The surge came from an in-app donation appeal and more blog posts, not from ads or data deals. Staff grew from 15 to 24. Turns out asking users for money works better than selling them.
