What if the code you wrote in your spare time became the foundation of a global tech company?

That’s exactly what happened to Peter Steinberger.

From Indie Developer to Industry Name

Peter wasn’t backed by venture capital.
He didn’t launch with a huge team.
He didn’t even start with a big vision of building a global company.

He was simply a passionate iOS developer who loved creating high-quality tools. While working on apps, he noticed a common problem: developers struggled to handle PDFs smoothly on mobile devices.

So he built his own solution.

That side project would later become PSPDFKit, a powerful PDF framework used by major companies around the world.

The Turning Point

Instead of chasing ad revenue or consumer downloads, Peter made a strategic decision:

He would sell directly to businesses and developers.

This meant:

  • Higher-value customers

  • Recurring revenue

  • Stronger long-term growth

Soon, major enterprises started using PSPDFKit in their apps. What began as a personal tool turned into a high-revenue B2B software company.

Building Without the Hype

While many startups chased funding rounds and headlines, Peter focused on:

  • Product quality

  • Developer experience

  • Sustainable growth

  • Profitable business models

This quiet, product-first strategy allowed the company to scale globally without the usual startup chaos.

The Result

Over time, PSPDFKit became:

  • A trusted name in developer tools

  • Used by major enterprises worldwide

  • A company with millions in annual revenue

  • A success story built on code, not hype

All from a developer who started with a simple problem and a single solution.

The Lesson for Builders

Peter’s journey proves something powerful:

You don’t need viral marketing.
You don’t need millions in funding.
You don’t need a big team.

Sometimes, a single useful tool built well can change your entire life.

And in today’s world of AI, crypto, and open-source innovation, the next Peter Steinberger could be anyone… even you.
