 Second, know when it's better to use of the shelf, so AI solutions, build, customize it, the AI solution in-house or hire a company or even wait for a big tech to launch it. So I surfaced the first AI machine learning wave, which was the AI for images. And I fell a lot in the trap of developing things in-house. And then six months later, a big tech delivers the same feature. And then two more months, their solution is better than ours and we had to migrate for theirs. A good rule of thumb in this matter is the functionality is something that's general, that can be applicable for a lot of companies, regardless of their domain. Probably a big tech will launch the solution or if you build the solution, they will buy your company. That's a good strategy as well.
