On a recent podcost MrBeast said he's building a data & analytics company.
My bet is It's going to become a unicorn in < 1 year of launch.
He has the hardest part done: building a brand
The next generation of billion dollar tech companies are going be built off creators.

Obviously if he hires the wrong people, specifically those without the right tech expertise, it's going to fail.
But when you have access to 100m people and hiring policy like he does it's almost impossible to fail.

Another example of this is @DougDeMuro + cars&bids.
He promotes his company to his audience every video.
5M People get blasted with "cars and bids is an automotive..."
0$ in ad spend, tight customer <-> company coupling = recipe for success.

But I don't really see any other creators doing this. Most go the route of selling Merch or some random tech products.
The next 2-3 years will change though. There just needs to be 1 catalyst (aka mr beast)

If anything, small scale founders should reach out to these massive creators.
They have the tech background. Pair that with a massive audience = a MASSIVE headstart
