Zipz, a single serve wine company, made Shark Tank history last week by closing the biggest deal in the show’s history. The company makes a wine-by-the-glass product that is covered in a protective wrapping to increase its shelf life. Zips came to Shark Tank seeking $2.5 million for 10 percent of the company, which it received from Kevin O’Leary along with some other contingencies. To date, the company has raised $8.5 million from 25 backers, including six former Goldman Sachs partners.
