I use this site to deconstruct how things work:

  1. I pick a skill I want to be good at.
  2. I research and experiment to uncover its principles. I question the assumptions behind its conventional teaching.
  3. "The difference between knowledge and wisdom is experience,” so I get my hands dirty and experiment.
  4. I rewrite until I have a handbook that is interesting, concise, and effective.
  5. I post updates to Twitter along the way.
  6. I release the handbook for free. Each takes around 1,000 hours. They're read by about a million people every year.

I release handbooks instead of books because books are worse for education:

  1. Educational books become outdated, whereas I update handbooks.
  2. Books lack audio and video, which can be critical for effective learning.
  3. Books contain boring filler to reach page count requirements.
  4. Book excerpts can't be linked. So, people rarely return to re-read.

I announce new handbooks via my newsletter, which you can learn about here.

A quote

“I had lunch with a producer a few years ago. At some point, I said, 'Every film I do, I have to believe that I’m making the best film that’s ever been made.' He was absolutely shocked by this. It never occurred to him that someone would think like that. And that, to me, was truly shocking—because films are really hard to make. They're all-consuming. Your family life and everything else goes into it for two years. So it had never occurred to me that there were people doing it who weren’t trying to make the best film that ever was. Why would you otherwise? Even if it’s not going to be the best film that’s ever been made, you have to believe it could.” —Christopher Nolan

I founded Demand Curve, a Y Combinator startup that grows other companies: We train teams in marketing, we help them hire marketers, and we run a growth agency. Clients include Microsoft, Segment, Basecamp, and Zendesk.

I also wrote TechCrunch's growth marketing column and occasionally appear on podcasts to chat about growth.

In my free time, I write handbooks and blog posts on Julian.com. They're read by 1 million+ people per year.

I also created Velocity, a web animation engine used by Samsung, Uber, WhatsApp, and thousands more. Velocity was awarded the Stripe Open Source Grant. I was interviewed about my open source work on Forbes.

I'm an active angel investor across all stages, sectors, and geographies. Reach out if you're growing quickly and think I can be of help.
