I spoke with an entrepreneur whose company is building a new, disruptive product for the education sector. One of the challenges he’s facing is that none of the company’s co-founders have worked in the education sector before. He wondered if he should hire someone with some relevant experience.

Another entrepreneur friend of mine is building a tool that is catered to the public sector. The company is struggling to scale as a business. The sales process is too slow. The product is becoming too specific for one sector.

In both cases when these entrepreneurs asked for my advice, I told them: Don’t be a parasite if you want to be a disruptor.

There are so many verticals out there that still have not been fully transformed by the Internet — education, public sector, book publishing, the list goes one. But it’s extremely hard to transform any industry if you have a lot of dependencies with the old systems. You can’t think out of the box. Your sales cycle is too long. And often you end up with a product or a service that is incremental at best rather than revolutionary.

Now, there’s nothing wrong with that. In fact, a lot of people have built great businesses by providing incremental solutions like consulting services to the government. But, if you want to build something truly transformative and net-native, then you have to stay as far away from the traditional systems as possible and draw closer to your end users or customers.

If you want to create something truly game-changing and be a disruptor, you can’t begin the journey as a parasite.
