Hey Rational Optimist,
“Pessimists sound smart. Optimists make money.”
That quote from tech founder Nat Friedman has guided most of my career, except for the very beginning.
I actually started out as a cynic. But it didn’t work in investing, or in life.
I’ve watched the opposite prove true again and again: smart-sounding people explain why something can’t work… right up until someone builds it anyway.
We’ve been fortunate to build a very deep network of founders at ROS. Many are #1 in the world in their burgeoning fields, whether it be small nuclear reactors, supersonic jets, or asteroid mining.
Now you can join me as I talk to these innovators building the future with our new YouTube show and podcast: Optimists Make Money.
My aim with Optimists Make Money is twofold.
One, to give you closer access to the network of extraordinary founders we continue to build.
Two, to better understand and predict the future by talking to the people directly building it.
Theories and thinkers are great. But this podcast will feature my conversations with doers. The founder-CEOs with dirty fingernails who are in the trenches building new, cutting-edge businesses.
On this week’s debut episode, I talk with AstroForge CEO Matt Gialich on his plan to mine trillions of dollars’ worth of platinum from asteroids.

His startup AstroForge is trying to do something no company has ever pulled off: land on an asteroid, mine tens of millions of dollars’ worth of platinum metals … and bring the refined ore back home to Earth safely.
Listen to Matt for five minutes, and you’ll understand why founders like him are the ones building the future.
