Lecture 6 - Growth (Alex Schultz)
Executive Summary
Alex Schultz teaches a growth-focused lecture in Stanford's 2014 How to Start a Startup course, starting with retention and the moment users first understand a product's value. He explains choosing a company-wide metric, aligning acquisition with real activity, and using examples from eBay, Facebook, Hotmail and PayPal to discuss distribution. Notes cover selected business passages from roughly 49,700 characters of public auto-captions for the 47-minute lecture; the closing section is not covered. Course identity is checked against the official archive and the date is the October 9, 2014 video upload. Company statistics, search tactics and platform behavior are historical examples, not current verified guidance. The introductory physics example is not summarized.
Key Takeaways
Check retention before scaling acquisition
Schultz says growth tactics cannot rescue a product people do not keep using. He recommends looking at activity by acquisition cohort and whether retention stabilizes, rather than celebrating sign-ups alone.
Choose a useful company-wide metric
Different businesses need different measures. Schultz contrasts active users, messages sent, nights booked and merchandise volume as examples of metrics tied to actual product use rather than simple registration totals.
Chase activated users
At eBay he changed affiliates' payment from confirmed registered users to activated ones who then bid or bought. Registrations fell about 20 percent but activated users only about 5 percent, and activated growth then accelerated.
Find the magic moment
Landing someone on a search results page for what they want to buy gets them excited. Registration-first pages give people no magic moment, so drive them toward the moment that hooks them.
Marketing is work
He says that build it and they will come is the Valley mantra and he does not believe it, giving the Pinterest example as driven by marketing.
How virality works
Hotmail and PayPal went viral through a high conversion rate, with Hotmail sending a link with every email and PayPal paying people to invite friends. Facebook grew mostly by word of mouth.
International and SEO
Facebook internationalized too late and had to fight clones in many countries. For SEO, research keywords, win links from high-authority sites, and link internally. A directory added at Facebook boosted SEO traffic 100 times.

Core Frameworks & Ideas
Retention before growth tactics
The lecture asks whether early users continue to use the product over time. If they do not, the problem may be the product or its market fit rather than the acquisition channel.
North star and magic moment
A shared metric helps the team choose what to improve. The first experience that reveals value to a user should connect to that metric, such as finding friends or an item they want.
Payload, frequency and conversion
Schultz uses these three factors to examine a viral loop. His examples show that a small audience per message can still spread a product when messages recur and recipients have a strong reason to join.
Actionable Next Steps

- ✓Pay partners for activated users, not just sign-ups.
- ✓Check that every important page can be reached by search engines in a few clicks.
- ✓Review retention by acquisition cohort before raising your acquisition budget.
