In accelerators, that means having more consistency in what factors work, and more selectiveness. Take things that repeatably work and use that.
In my opinion, companies like Google build one hit after another, internally, by re-using their internal platform and users and virality. There are failures but not as much as with startups. But it all benefits from internal resources, server farms, infrastructure, user base etc.
If you are outside such a company, use an open source platform that worked for others. We are working on such a platform and will probably take partners in a couple years, to build apps for our several million users, and provide them with all the infrastructure to try things out and take a % if it works out.
