This math is off because the vast majority of Silver sponsors are at $10k, and some of the sponsors at all levels are in-kind, meaning we get something other than cash from them.

In 2019 we spent $3.35M in cash (we came in a little under our projected budget of $3.6M). We raised $3.82M in cash between sponsors, grants, and individual giving.

(For those who aren't aware, parent is the executive director of LE).

Thanks for the $3.35M/$3.82M figures -- is this published officially anywhere? $3.6M was the latest figure I was able to find on your website: https://letsencrypt.org/2018/12/31/looking-forward-to-2019.h...

The philanthropy-based funding model, coupled with the fact that this is now load-bearing Internet infrastructure, still makes me quite nervous, but I'm glad that you're able to sock away ~$500k for a rainy day.

Well I did say it’s rough, I wasn’t claiming to know your finances, I also couldn’t know the amount from donations :)
