Explosive Growth by Cliff Lerner, published by Lioncrest Publishing in 2017, is a growth book wrapped in a founder story. Lerner was the CEO of Snap Interactive, the company behind the online dating app Are You Interested (AYI). The company bet its future on Facebook’s platform, gained around 100,000 new users a day at its peak and passed 100 million users, while also losing 78 million dollars along the way. The book shares what he learned from both sides of that ride.
What is Explosive Growth about?
The book follows Snap Interactive from a cash-starved startup to a company riding one of the biggest distribution waves of its era. When Facebook opened its platform to outside apps, Lerner’s team moved fast, built a dating app that lived inside the social network and found that it could grow almost for free through invitations and social features. The story then turns to the cost of that dependence: rule changes, rising competition and the hard work of keeping users once the easy growth ended.
Around the narrative, Lerner lays out the growth frameworks his team used. He covers building a product that spreads by design, choosing the few metrics that tell you whether the business is healthy, testing ideas quickly, running viral loops and getting media coverage without paying for ads. He also writes about company culture, hiring people who love experimenting and keeping a team motivated through setbacks.
What makes the book different from most growth guides is its honesty about losses. Lerner is open about bad bets and the price of fast growth, and he presents the mistakes as part of the lesson rather than a footnote.
What are the main lessons for founders?
- Treat a platform as a gift with a deadline. A new channel like an app store or social network can deliver users cheaply for a while. Use the window to build direct relationships you own.
- Build sharing into the product. Growth that comes from people using the product, such as inviting friends or showing activity, compounds. Marketing bolted on later rarely does.
- Choose metrics that matter. Daily active users, retention and revenue per user tell a truer story than total downloads.
- Test constantly and cheaply. Small experiments on screens, messages and features add up. Make testing a weekly routine, not a project.
- Get attention creatively. Clever surveys, data stories and stunts can earn press coverage that a small startup could never buy.
Who should read Explosive Growth?
The book suits founders of consumer apps, marketplaces and social products, especially those growing through one dominant channel such as a social network, an app store or a search engine. Growth marketers and product managers will find the frameworks easy to apply. It also helps any founder who wants a candid account of what fast growth feels like from the inside.
B2B founders and companies selling through sales teams will find little that applies directly. Readers wanting a polished, research-based framework should look elsewhere, because this is one founder’s experience.
How do you put Explosive Growth to work this week?
- List every channel that brings you users and mark the share each one delivers. If one channel brings more than half, write down what you would do if it vanished tomorrow.
- Pick three metrics that show real value for your users and set up a simple weekly report.
- Design one small sharing feature, such as an invite or a share prompt after a success moment, and test it with a portion of your users.
The free Digital Marketing module in the Fe/male Switch Startup School helps you plan channels beyond a single platform.
Where does Explosive Growth fall short?
The examples come from the Facebook app era of the late 2000s and early 2010s, a window that has long closed, so some tactics no longer work. The book is a personal account and lacks the breadth of research-based growth books. It also spends less time on how to build lasting retention and sound unit economics, which is exactly where the company struggled. Pair it with Hacking Growth for a structured testing process and The Cold Start Problem for a deeper look at network effects.
