Tim's secret feature inspired the subscription model for channels on Twitch and across the internet.

We shifted The Onion's business model to prioritize readers over advertisers, launching a subscription service that has successfully attracted tens of thousands of subscribers.

Subscriptions are powerful because they feel less expensive than a flat fee, leading to more people willing to pay over time.

In 2010, we launched Reddit Gold as a subscription service out of desperation to generate revenue since advertising wasn't sufficient, and it surprisingly raised more money in one day than we made in ads that month.

After launching the paywall, I forgot about the Captions app, but later discovered it was generating over $500,000 in revenue with no employees working on it, and users were retaining it without any support.

I am the CEO of Substack, which makes it simple to start a paid newsletter and also allows audio integration.

I chose a subscription-based model because it aligns with the benefit users receive from having more users, and it's a common practice in our industry.

After leaving Scribd, I immediately discussed new ideas with Paul Graham, and we decided to apply to Y Combinator again, even though we didn't have a product yet. I co-founded a subscription billing service called PipePay, but we didn't want to compete directly with Stripe, which was doing really well at the time.

By September 2014, we officially made Instapaper free and launched a new subscription pricing model, which led to a recovery in revenue and a growth trajectory for the app.
