Company logos on a marketing page are a game: "how best can we leverage our userbase to gain credibility?". I can't speak to Hypercontext (maybe they do have a relationship with Netflix!) but in general when you see a logo on the marketing page of a startup it means "we have _one person_ from this company that signed up to our service with an @company.com email".

You don't need to sell to Netflix to get their logo on your homepage, you just need to convince one person with an @netflix.com email to sign up. Much easier :)
