Lol, think from the founder / teams perspectives. Giving 80% ownership would be insane. How could you build a company like that? It’s not so simple.

Those are called Spin-Ins. Now abandoned, Cisco once pioneered this model: https://news.ycombinator.com/item?id=8348900

The closest Google had to it was Area 120, which has also been abandoned?

Isn't this what incubators do now?

The value add by most incubators and accelerators is minimal, compared to what a large parent company can provide though.

The sort of people who would accept those terms are not the sort of people you want to build a startup.

I might take that 80% deal, for the right killer IP that I knew how to apply in a marketable way, and a couple years of sufficient GCP credits.

I might bootstrap revenue without much hiring, so that business success means the team does better financially than the sure-thing FIRE if they'd just taken a FAANG job and grinded promotions.

This business giving away 80% equity would lean on the value of IP, and on knowing how to be very effective with solo/small teams -- not 'scale' in the sense of trying to herd hundreds of software and product and business people. (This is another thing that big orgs can have trouble doing, and so sometimes do insulated spinoffs/units instead, just to unburden people.)

I think they basically employ that model already at Area 120 [0]. This interview platform called Byteboard was spun out of Area 120 a couple of years ago, and I imagine Google has a large ownership stake in it, while avoiding the brand association [1].
