1. Growth key is retention
2. Network effect - people use what others use
3. Build more category

one of the best videos ive ever watched

One of my favs from this year's series.

Great talk. Especially loved you reiterating on focus on channel, then targeting, then creative.

There were sending out a lot of spam emails. I remember I got 5-6 everyday asking to sign up. That time public email service users were asked to share they contacts list with the app, so that is how they got hold of my emails addresses.

Very insightful - should be mandatory to go through this series before starting a startup

Great presentation. Very thought provoking statement @ 24:53
"The purpose of a Startup is to grow."

This was great! Please do more slides/presentation type talks like this instead of panels. Panels seem to have orders of magnitude fewer deep introspective takeaways to communicate.

I did the math at 11:14. It was 800,000.
1 (New User) - 1.3 (Churn) + 1.1 (Resurrecting Users) = 0.8 - Add the units and its 800,000.

Pure gold

It fascinates me how knowledge like this is free on the internet, learning from entrepreneurs like Alex is so extremely valuable and people rather be watching Netflix all the time to entertain themselves

Personalized communication is very crucial.

My favorite lecture so far

Looking forward to the day I will also be in Stanford to give a lecture as a Founder.

I watch people on youtube for long years. This is in my Top10 list.  This guy has a unique shaped brain with filled so much useful information. Loved.

As an early-stage founder currently reading 'Hacking Growth' by Sean Ellis and Morgan Brown, I can relate to what Mr. Alex said about using different retention metrics based on the category you're in. A Saas business retention metric may be different from an E-commerce's.

Tons of take home messages. Worth taking some time to digest.

its 2025! And im here!

Great but anyone could help to clarify what he talks about at 15:29 and further. Is it about the curve that will become flat at some point so you may assume that it will be at the same level +100 days from that point OR it is that you may take curve representing the retention and use it to predict other metrics?

1.Retention is very important
2.Understand what's going on，identify the opportunities in that data you've understood,and then execute against it.
3.Best of talks about making decisions with 70% of the data not 90% of the data.
4.Move fast, focus on retention and have one key metric that you care about for your company growth.
