Catharine Arnston, owner of a start-up selling a product called ENERGYbits, appeared on “Shark Tank” in Season 8, and asked for a $500,000 investment for 5% equity. The judges weren't completely sold on the product, and Arnston, unwilling to compromise, walked away. Here’s what has happened to her product since then.

Today, ENERGYbits sells four tablet products, including BEAUTYbits, ENERGYbits, RECOVERYbits, and VITALITYbits, all containing different combinations of algae types, thus catering to buyers looking for different results. As of 2021, the company is raking in $4 million each year (via Shark Tank Blog).

Arnston has not only expanded her product selection and the company's community outreach. In 2018, Arnston and ENERGYbits partnered with Family Reach, an organization that helps to provide financial relief for cancer patients, as a sponsor in an effort to further assist people with cancer and other chronic illnesses.
