At one of last Blender conferences, the founder (and at that time CEO) gave some insights about funding and compared it to Thunderbird. https://youtu.be/VZ5022VaMmA?si=m1hD9wEQ16s8Zu3b&t=1297 ;

Fore More recent numbers: In 2024[1] (last info I found), Blender had 3.1m € in donations (600k more than the year before) and Thunderbird had around 9m € [2].

I kind of get it, Blender is way more niche than Thunderbird, but imagine what they could do with even more money.

[1] https://download.blender.org/foundation/Blender-Foundation-A... on page 76 [2] https://blog.thunderbird.net/2025/10/state-of-the-bird-2024-... I did the money conversion based on today's exchange rates

A quick AI Google search and some fact-checking later, and yeah. At least as of 2 years ago, Thunderbird was getting 3x the contributions that Blender was.

It just goes to show you how badly managed Thunderbird is, since Blender is doing so much more with the money. I'm more and more disappointed with Mozilla all the time.

Market size is different: everyone needs a mail client, but not everyone needs 3d modelling.
