Disguising a blog post as a native advertisement for your startup is not clever or "growth hacking."
I don't think they're trying to "disguise" anything. The article is informative, if they have a solution to present, use it if you agree, don't use it if you don't. They mention their company twice towards the bottom of the article, a place you won't get if you don't find the content interesting.
While the article is informative, it's also an ad for a recruiting agency, and the advice has to be interpreted in that light. Still, if this is the future of "native advertising", I like it.
