The Idea:

Dan Ni had the kind of career that normally makes your parents stop worrying.

A Yale degree. A job in trading. A fairly clear route to making a lot of money.

Then health problems sent him back to his parents' house.

With his original career on hold, he taught himself to code and built ScraperAPI. Getting his first ten paying customers made the business feel real. Eventually, he had something valuable enough to sell.

But alongside the software business, he started something considerably less complicated.

An email.

Keeping up with technology had become a job in itself. Too many tabs. Too many articles. Too much time spent finding the interesting bits.

Ni's answer was to do that work for people: a short daily roundup of the stories that mattered, written for people working in tech.

No revolutionary technology. Just a useful filter, delivered consistently.

This was the beginning of TLDR.

The Execution:

• 2012: Ni graduates from Yale and goes into trading. Health problems interrupt that career, so he returns home and teaches himself to code.
• Before TLDR: He builds ScraperAPI. As the business grows, he learns to hire people better at particular jobs than he is—a useful lesson for what comes next.
• 2018: He launches TLDR as a side project and invites existing software users to subscribe. His first audience is already sitting in his inbox.
• 2018–2019: He tests Reddit and Quora ads alongside newsletter cross-promotions. As the audience grows, reader referrals become a bigger driver.
• 2020: He sells ScraperAPI, freeing up time and money for his next chapter. In his exit interview, TLDR is already on the list.
• Around 2022: At roughly 200,000 subscribers, he brings in help running paid subscriber acquisition. The side project starts getting a proper growth engine.
• 2024: TLDR records its first year of eight-figure revenue—and is profitable. A daily email has become a very serious business.
