Mark Cuban announced that after leaving Shark Tank after 13 years, his investment record was brought up again. This guy has invested in a total of 85 companies, with his biggest investment being $150K in Tower Paddle Boards, which later yielded dividends of over a million – this is what true long-term returns look like.

His secret to success is actually not complicated: identify the right track + invest in the right people. From fitness snacks to SAT training, and then to horror-themed experience venues, Cuban has invested in industries with strong demand. Especially Tower Paddle Boards and Nuts'N More, which not only survived but also achieved a six-figure annual income.

The most interesting thing is his investment in Prep Expert in 2016—$250,000 for a 20% equity stake, and then helping the company achieve an annual revenue of $5 million. This shows that Mark Cuban's value lies not only in money but also in his business sense and celebrity effect.

To turn things around in Shark Tank, the key lies in these three points: a product with genuine demand, a reliable founder, and an investor who can leverage resources. Mark Cuban has all three.
