Let's make this birthday one to remember.

51 years old (Born on December 12, 1973)

Happy Birthday, Tony! From selling LinkExchange to Microsoft for a cool $265 million back in '99, to revolutionizing customer service at Zappos.com—your journey has been nothing short of legendary. You've proven that happiness and shoe shopping can indeed go hand-in-hand!

Here's wishing you another year filled with innovation, inspiration, and perhaps even more quirky company culture experiments. May your birthday be as memorable as the time you convinced us all that delivering shoes overnight was not just possible—but essential. Cheers to you, Tony—the entrepreneur who taught us all how to step into success comfortably (and stylishly)!
