Dear Daniel Aegerter,
This is a note of gratitude.
Over the last 6 months, we have been able to accomplish great things. This is extremely generic and terrible copy. I can't even believe I am writing this.
But I think this will be a good way of reaching Aegerter, in a website rather than a PDF, to honor him. Emphasize that we see him as a great funder, not only for his philanthropy which we have benefitted from, but because he takes a view on investing that we believe deeply in.
Show a unique determination and stamina, an elegant solution to a massive problem. Creating our niche.
Show that Dr. Keefer has been a visionary and a leader.
Why now is the moment, and demonstrate long-term thinking (we need to be building the social and political foundation now for the technologies of the future or something like this).
