1. If u build it, they will come X IF U BUILD IT, THEY WONT COME 2. 2 Skills needed at the beginnging. a. Do a lot of things that dont feel right. b. Do things dont scale. 3. Go to the users, and watch how they use it - so start with users near u who has that problems. 4. Startups take off because founders make them take off 5. Retention is the best way to determine product market fit. cont : 16.43

I'm always excited when i hear "Retention"

Retention as the product-fit evidence is great. Many times we think too much on the acquisition in the beginning. Although it’s important to acquire users, if retention is low (high churn rate), you’re just bringing more people who will be somehow frustrated with your product.

Great class about growth for startups!! Congrats YC team and Gustaf for the rich content.

This is a gold mine.. please add each topic as a new series..

This is about one of the best talks I have received here! Gustaf nailed it! Thank you.

Excellent. Concise and precise

So grateful for this channel. God bless.

Great Talk!!! I find it really full of value, i kind of knew the story about how Airbnb took off,but didnt know that the guys that went to took the photos were actually the founders!!! Now i get what you mean with " things that dont scale and feel unconventional" . The teaching of the metrics were brilliant too, im a fan of measuring everything and now i understand more about measuring what really matters to grow. Thanks a lot for this! Greetings from Argentina 🇦🇷👌

Probably the best Ycombinator video ever

Thanks Gustaf for your useful advices!

Thank you Gustaf. This is very informative video. Some of the points discussed are very very helpful. Very good presentation. 👍 My gratitude to Y Combinator as well.

Thank you, insightful 👍

Thank you Gustaf!!!!

Thank you ✪

I work as a contractor for a major government agency, and its kind of sad we don't A/B test. We did an AB test, where we literally had one universe, but with two opposing colliding galaxies (aka. differing control/experiment on different pages of the same site, shown to all users)

Great talk!

I loved this talk. I keep coming back to this channel every few days. You sure have a product market fit Y Combinator! But, hey, this is a free channel, so, this doesn't count, I guess. ;)

Thank you for the insights

Great one Gustaf. 🙌🙌🙌 YC

Gathered More Info ! Thanks !

I love YC

Thanks bro

Massage chairs business are less expensive amongst all vending machine in market. 26. It really amazed me how big I earned for the first week of my vending machine business. This is really a good business idea

How does this whole "PMF = retention" formula work if it's a one-off business model that solves a problem for people which they typically only encounter once (or rarely) in their life? For example, stuff like ancestry research, intelligence tests, Gallup Strengths Finder etc. How/when do you know your product fits the market? NPS/CSAT? Also, more generally, why not use the market share of the target market as an indicator of PMF? If 3-5% are the early adopters needed to "cross the chasm" into the "growth stage" resp. the critical mass needed to go from push to pull marketing (M2M, network effects etc.) needed for expontential growth, why not use this market share as a potential threshold value for PMF? Is it too abstract? In a similar vein, I struggle with YC's general advice against paid marketing; to me, it seems very plausible to get closer to said 3-5% MS and build momentum faster and more linear and predictable in the target market this way. As long as the runway allows it...🤷‍♀️

11:22 I think Riders is a typo and it should just be Rides. Isn't Ride the metric and the weekly/monthly frequency is how often the Rider takes a Ride - that would be consistent with Airbnb when a Guest books a Stay at least Annually

Question for anyone who can help. At -26:21 the graph for Lyft. The first plot point, week 0 is at 50% for 10 riders. Why isn’t that point at 100%?

Anybody know what metrics should startups like AirBnB measure that is VC approved?
