Lecture 1 - How to Start a Startup (Sam Altman, Dustin Moskovitz)

Key ideas

Sam Altman lays out why a startup needs a strong idea and a product a few users love; Dustin Moskovitz weighs the bad and good reasons to start one.

From YouTube’s captions. Quotes link to the moment they are said.

  1. 1

    The idea matters more than people admit

    Altman says the pivot-happy view that ideas don't matter has gone too far: great execution on a bad idea goes nowhere. He favors mission-driven ideas that look bad at first, aimed at small markets that are growing fast.

  2. 2

    Make something a few users love

    Altman argues it is far easier to expand from a product a small group loves than from one many people merely like. Until that is working, founders should do little besides build the product and talk to users.

  3. 3

    Recruit early users by hand

    Altman advises getting the first users manually, staying very close to them, and building a tight loop that turns their feedback into product changes; organic word-of-mouth growth is the sign it is working.

  4. 4

    Glamour, control and money are poor reasons

    Moskovitz says founding is mostly stressful desk work, the CEO serves everyone else's priorities rather than setting the rules, and early employees at a winning company can often earn and achieve more than a founder.

  5. 5

    Start one when you can't not do it

    Moskovitz's best reason is a problem you are so passionate about, and so well suited to, that you would build it anyway, as he and Justin Rosenstein did with Asana while still at Facebook.

In their words

“Great execution towards a terrible idea will get you nowhere.”
