Looking for a word that describes a little known but nevertheless influential person, group, etc

Heard an old joke about someone trying to namedrop. The person they were talking to didn’t know who they were talking about, so they said, “Well, they really are very famous, even though most people don’t know who they are.”

But there’s a kernel of truth in that old joke, namely that someone not all that well known can still be very influential, though they are by definition not very famous. Further, certain people really like the idea of knowing people like this, since it makes them feel like they are “in the know”. I’m not talking about conspiracy theories, like the Head of the Bilderbergers or Masons or something. I mean, perhaps there is some fashion designer that fashion designers are all copying, or some music mogul who pretty much decides what the next pop music style is going to be. And then the internet is rife with urban legends of people who can build up a product’s brand through anonymous viral marketing.

Is there a single word for people, organizations, what have you, that fit this description?

A Matchstick puzzle with a little twist

Here is a matchstick puzzle with TWO (possibly more) solutions.

Matchstick Puzzle

There are two types of matchsticks.

1 Short (eight and = sign) Total 9

2 Long ( All ones) Total 4

Please move 3 matchsticks and make the equation right.

Rules

  • Must move 3 matchsticks, one or two moves not allowed.

  • Cannot remove matchsticks

  • Must move at least one of each type ( either 2 long ones and 1 short or 1 long one and 2 short)

  • No < or > or “not equal to” allowed

  • No looking from the top or mirror image

  • Except for 1, other digits (2,3,4,5,6,7,8 and 9) use short match sticks only.

I have 2 solutions: One kind of obvious but another requires lateral thinking which is what I am looking for. Please give both the answers together

Question: Does our President have a little tiny wee-wee which he uses on animals?

“Ladies and Gentlemen, may I present your president,” Stormy Daniels tweeted in response. “In addition to his…umm…shortcomings, he has demonstrated his incompetence, hatred of women and lack of self control on Twitter AGAIN! And perhaps a penchant for bestiality. Game on, Tiny.”

Question: My cat has scabs on her neck and is itching a little more than she usually does.?

She doesn’t have fleas or ticks(I had her checked out), I don’t know if it’s a food allergy(just switched her food recently from Purina to Rachael Ray) so I don’t know if that’s the problem. And someone told be it might be that she has dry skin so I bought stuff for that. Please help!
