The one question I ask every founder
What’s the name of one human being whose problem you’ve meaningfully solved?
It’s the heart of Start With One, the framework I teach. When anyone can build anything, the person is the proof.
In their words
“Your class truly made an impact on me, so much that I made my yearbook quote ‘Start With One.’”
“One of his superpowers is customer conversations. He builds trust fast and is world class at extracting signal from users and turning it into revenue and product clarity.”
“He’s dramatically impacted my life as a CEO. It’s likely we wouldn’t be as far as we are without Daniel’s help.”
What I live by
To live fully, love deeply, and help others become the best versions of themselves.
Bring your one person.
