WHAT IT’S REALLY ABOUT
Angel Investor Reveals Cold Start Secrets Behind Network-Effect Giants
- Andrew Chen, general partner at Andreessen Horowitz, explains how network effects underpin the world’s biggest products, from social apps to marketplaces and collaboration tools. He contrasts the traditional, centralized venture model with today’s decentralized, globally accessible startup ecosystem, enabled by remote work, social media, and Web3. A core focus is the “cold start problem”: why products whose value depends on other users are almost worthless at the beginning and must grow through small, dense “atomic networks” rather than broad blasts. Throughout, he illustrates with case studies like Google+ vs. Facebook, Uber, Tinder, Clubhouse, Substack, and crypto, and he argues that creators and users will increasingly own and shape the networks they build.
IDEAS WORTH REMEMBERING
5 ideasTreat public content as a core investing tool, not a side project.
Chen’s long-form writing and book both clarify his thinking and broadcast his expertise, improving deal flow (sourcing), decision quality (picking), attractiveness to founders (winning), and his ability to help portfolio companies (operating).
Understand network effects: value grows with users—but so does fragility.
Products like social networks, marketplaces, and collaboration tools become more valuable as more people join, but are nearly worthless at the beginning or when a user’s contacts aren’t active, which is the essence of the cold start problem.
Start with dense “atomic networks,” not big launches and vanity metrics.
Instead of chasing huge top-line user numbers, founders should manually build small, self-sustaining networks (e.g., a campus for Tinder, a city for Uber, a team for Slack) and then replicate those units, as broad, shallow signups rarely produce real engagement.
Do unscalable things early to seed the right users and interactions.
Borrowing from Paul Graham’s “Do Things That Don’t Scale,” Chen highlights tactics like Stripe onboarding Y Combinator founders one by one or Tinder sponsoring specific campus parties—high-touch methods that create strong early usage patterns and quality networks.
Focus on the hard side of the network and serve it obsessively.
Every network has a scarce, high-value side (Uber drivers, YouTube creators, attractive dating profiles, Substack’s top writers); products win by offering unique benefits or formats that make these participants prefer the new platform over entrenched incumbents.
WORDS WORTH SAVING
5 quotesFor this style of product, these are products where the more users that use them, the more valuable the products become.
— Andrew Chen
A product that is more valuable when more people use it is not valuable when no one’s using it. And that is the cold start problem.
— Andrew Chen
The problem is that’s just not how startups should create network effects-based companies. You have to be very, very manual.
— Andrew Chen
It’s not necessarily about having the widest access to potential audience. It’s about having a particular type of person on the same platform that creates a magnified network effect.
— Chris Williamson
Most people think of viral growth as putting out a really cool video that everyone shares. That’s not what I mean. There is a science behind viral growth.
