WHAT IT’S REALLY ABOUT
Network Effects Explained: Bootstrapping, Measuring, and Defending Marketplaces and Platforms
- Anu Hariharan defines a network effect as a platform becoming more valuable to existing users as more users join, and stresses it is distinct from fast growth or viral adoption.
- Both guests argue that retention-style metrics, such as Facebook's daily-to-monthly active ratio, reveal real network effects, while Angry Birds-style download curves reflect only viral growth.
- Case studies show founders solve the chicken-and-egg problem with deliberate hacks and small-scale validation, such as OpenTable's restaurant tools, Facebook's Harvard focus, and WhatsApp's tiny feedback group.
- The guests discuss paid versus organic acquisition, monetization timing, and the view that growth versus monetization is a false dichotomy, especially for marketplaces with transactions flowing through them.
- In audience Q&A, Jeff Jordan covers how OpenTable survived a funding drought that wiped out competitors, why branded marketplaces beat white-label ones, whether brands have network effects, data network effects, and how external shocks affect networks.
IDEAS WORTH REMEMBERING
5 ideasGrowth is not the same as a network effect.
Anu Hariharan says viral growth is speed of adoption, while a network effect is rising value to users as the network grows, which shows up in retention and engagement.
Retention reveals a network effect.
Facebook's daily-to-monthly active ratio rose from the mid-40s to 57%, and Jeff Jordan recalls Mark Zuckerberg telling him 53% of all historic users were active the day before.
Every successful network has a bootstrapping hack.
Jeff Jordan says investors look for a founder's theory on which side starts first; examples include OpenTable's restaurant tools, Facebook pre-populating the Harvard directories, and Instacart's initial markup.
Validate in a small test environment first.
Jeff Jordan advises running smaller experiments like OpenTable in San Francisco or Facebook at Harvard, and for local businesses wants to see the model replicate outside the founders' home market.
Overnight success is rare and networks can take years.
Airbnb took about 36 months to reach critical mass, Pinterest had nothing happen for two to three years, and OpenTable's network built extremely slowly.
WORDS WORTH SAVING
5 quotesSimply put, I think, uh, the simple definition is, as more users join the platform, it's more valuable to existing users.
— Anu Hariharan
Growth is different because in... especially as a s- as a startup in your early days, you're growing really fast. That's growth. But network effect is really value.
— Anu Hariharan
Virtually every marketplace we can think of did some, had some hack or hacks that enabled them to solve the- impossible chicken and egg problem.
— Jeff Jordan
One of the founder stories that's so entertaining and so, and almost always so patently false is the overnight success.
— Jeff Jordan
The thing that you don't want happening is where you're paying lots of marketing dollars to acquire users, and then when you sort of dial down your marketing dollars, the growth also slows down
