Mark Cuban is dishing out a little advice for Box in advance of its IPO: Focus on the financials.

Box, the content-collaboration company, filed to go public last night, and the deal could fetch the company a valuation of $2 billion.

Cuban, the billionaire investor and entrepreneur, was Box's first outside investor back in 2005. But a change in strategy at the company made him sell his stake about a year later.

Despite missing out on what could have been a nice payday when the company holds its initial public offering, Cuban seems unperturbed -- on Twitter at least -- and is warning about focusing on results.

According to its filing with the Securities and Exchange Commission, Box lost $168 million last year.
