Mark Cuban is bringing his 'Shark Tank' investments to Amazon's exclusive store

Mark Cuban has made a number of investments through his hit reality show "Shark Tank," where he appears as an investor. He's also seen how a "Shark Tank" appearance could instantly boost the sales of the companies he invests in.

But it looks like Cuban believes Amazon is the better platform to promote and sustain the sales of his portfolio companies. It's why he's bringing some of his "Shark Tank" companies to Amazon Exclusives, a site dedicated to products sold exclusively on Amazon.

"Amazon is the best in the world in online transactions," Cuban said in a statement.

According to Amazon, Cuban is bringing more than 100 items from about 20 of his portfolio companies, including the ones that previously appeared on "Shark Tank," such as Tower Paddle Boards and Nuts 'n More.

The products will be showcased under a section called "The Mark Cuban Collection" on Amazon Exclusives, but will be available on Amazon's main website as well.

Cuban's move also suggests more companies are seeing Amazon Exclusives as a viable platform for growing their businesses. Launched last year, Exclusives is a third party marketplace where sellers can sell their products exclusively on Amazon for added exposure and access to Amazon Prime's two-day shipping. Amazon takes a cut of their sales in return.

Cuban cited the "back-end support" and logistics that Amazon offers for customers as big benefits.

Amazon also shared updated numbers for its Exclusives service. Since last year, it's added 20,000 items, 60 of which went on to become one of the best sellers on Amazon's main site. Sales from the Exclusives store has passed $50 million in 2015, and it's been growing 15% a month since the start of the year, Amazon added.
