Being inside FB (or any other large company) has way more advantages than users entering the door.

Just the metrics and analytics that FB can gather on experiments is an insanely huge hill a regular startup can't climb. FB can gather and analise data at a scale, on so many markets and devices and demographics that none other plan tier at 3rd party integrations can hope to match. The SRE support you get, a 30 minute conversation with other great product managers, engineers, designers one meeting invite away, a history of what others have tried and what worked and what didn't, and so much more.

And if you get a VP to support you, even for a bit, we're basically talking about a torrent of money and resources being thrown at your project while you still drawn a 6 figure salary (plus benefits and bonus and stocks!). It's really apples to oranges here.
