A lot of musicians, athletes, and actors have found other means of making money while they are busy with their careers. Besides endorsements, we have seen smart celebrities make great businesses that end up becoming multi-million investments.

We can tell you that Pitt started Plan B productions, which produced the Oscar-winning "12 Years a Slave" and "Moonlight." What this means is that these celebrities don’t just wait for money to come to them, they go after it by investing wisely. What do you know about Gwyneth Paltrow besides her solid acting career?

Paltrow is among those who took an unusual business investment in a different niche that opened roads of success and wealth to her.  Paltrow has a lifestyle brand, Goop that ended up raising millions in venture capital. Goop was mocked for selling expensive knickknacks when she started but what started as a joke turned into a major business.

However, Paltrow convinced her investors that it was a promising investment and she ended up with a $20 million in venture capital funding. Paltrow is one of the many celebrities who has gone the extra miles in getting investors on their businesses. But considering the fact her company is worth $250 million today, all her efforts were worthwhile.
