There's a secondary goal here in that it benefits them to have a pool of skilled individuals out in the market who are familiar/expert on the Google platforms/technology.

So if they get a few hundred startups to use Google, most of them fail, a few hold steady, a few become heavy users of Google adn they make some money.

But - there's people from every one of those startups who now are familiar with how to use the Google platform and will potentially recommend/use Google at their next startup.
