Tiffany and Leon Chen started the nation’s first on-demand, baked-to-order, warm cookie delivery brand in 1999, as 19-year-old sophomores while in college. Over the next 20+ years, they've grown the business from one store to over 200 locations by the end of this year, employing thousands and being valued in the hundreds of millions of dollars.

They both graduated the University of Texas in 2001 and live in Austin with their boy/girl twins. In addition to running Tiff’s Treats, they often keynote at events such as the McCombs School of Business, University of Texas Commencement Address, numerous SXSW events and for companies like Southwest Airlines and Dell Technologies. They've been chosen as Ernst and Young Entrepreneurs of the Year and Leon has been named as an Outstanding Young Texas Ex. They are also investors in dozens of other companies and are active in supporting local non-profits such as Foster Angels of Central Texas, The Andy Roddick Foundation and the ConnorMan Foundation.

In 2022 they launched their book, "It's Not Just Cookies: Stories and Recipes From the Tiff's Treats Kitchen", published by HarperHorizon, which is currently in its second print run. The book details their hardships in building and growing a business, advice on fundraising, company culture, working with a spouse and of course, includes some recipes.
