Erfan Hardanian

I learn from history and borrow the best ideas. I find problems and build what fixes them.

Five things I’ve built. Pick one up.

What I’ve built

  • Compounding over decades fascinates me. The people who did it best wrote down how; I follow them, with tools they never had.

    Elie-lee

    A research system that looks for companies worth owning for decades.

  • At work, people held back from artificial intelligence over privacy. Yet without it, it’s hard to compete.

    Sayasah-yah

    Lets artificial intelligence work on a confidential file without seeing the names and numbers in it.

    87%

    of sensitive values caught in an outside set of 300 records.

  • On an old file server, one stolen password often opens every project folder.

    Kelikeh-lee

    Sets who can open each folder on a shared drive. It changes nothing until a person types how many folders will change.

    3 of 40

    folders open to one account after Keli, in one example.

  • Hundreds of founder stories, and nowhere to search them. So I built my own almanac, inspired by David Senra’s Founders podcast.

    Yadiyah-dee

    My notes on how founders and investors thought. Everything I build can ask them.

You have to keep learning because the world keeps changing and your competitors keep learning. You have to go to bed wiser than when you got up.
