alt Hacker News>Thunderbird is revenue positive
Hmm, I thought the for-profit Thunderbird pro hadn't launched yet?
I know Thunderbird is for profit, but what are they profitting from without the paid service, and how much of that profit is going into this unrelated Thunderbolt AI platform, exactly?
Thunderbird currently runs entirely on donations, even though they have paid products in the pipeline.
I think a piece of software running on donations is not running off "charity". It's just a business model to not charge every user. Similar to how Twitch streamers operate, or my local theater group.
You can read how they spent money in 2024 [1].
