Cal.com personal booking link R0 before enterprise sales

Why this can grow a startup

Cal.com's handbook is unusually specific about why the short-term growth motion stayed bottom-up. A single active customer shares a booking link many times in the first six months. If a small share of receivers make their own account, each active user creates several new users. The important part is that the link is both a utility and an invitation. It reaches buyers at the exact moment they are scheduling, not while they are reading an ad. The enterprise motion can come later, after employees and technical decision-makers have already used the product enough to become internal advocates. This is a useful lesson for any tool with a naturally shared artifact: make the artifact do quiet sales work before hiring the heavy sales machine.

Company example

Cal.com's handbook says the company chose short-term B2C bottom-up growth through cal.com/username links, estimating that one active customer shares a link 50 to 100 times in the first six months and can create an R0 of 5 to 10 new users if 10% of recipients sign up.
