Sean McDonald writes about time, life, and the future.

Sean is a 3x startup founder, and sometimes portrait artist.

This substack will focus on my time-centric professional work, but I’m doing it under my name, not my company - Sundial - because some projects, especially the clockchain, will be outside of that work. I might throw in some art here and there, too.

Please say hello. The only social platform I reliably use is twitter.com/sean_mcdonald. Thank you for reading.
