Hi there!

PreThink was founded by Dan Egan (me) in 2021 to help with on a wide array of personal finance and investing.

I've worked at Betterment since 2013 on how the design of personal finance apps influences behavior.

I love helping create new digital tools, data visualiations, science fiction, dogs, and snowboarding.

I studied economics and decision science, finishing my MSc in 2005. I've collaborated on a few academic papers, done a lot of public speaking and press, and some pretty cool coding. You can find me on Twitter and GitHub.

I'm based in NYC.

Why "PreThink?"

"He can look ahead. See what's coming. He can - prethink. Let's call it that. He can see into the future. Probably he doesn't perceive it as the future."

"No," Anita said thoughtfully. "It would seem like the present. He has a broader present. But his present lies ahead, not back.

Our present is related to the past. Only the past is certain, to us. To him, the future is certain. And he probably doesn't remember the past, any more than any animal remembers what happened."
