About Casper

Casper ( is a sleep brand that launched in 2014 with one perfect mattress sold directly to consumers — eliminating commission-driven, inflated prices. Its award-winning sleep surface was developed in-house, has a sleek design, and is delivered in a small, "how did they do that?" sized box. A year and a half after launching the mattress, Casper expanded its universally comfortable product line, which now includes a perfect pillow and sheets.

The company is one of the fastest growing consumer brands of all time with more than 100 full-time employees, $100M in revenue for 2015, and 100,000 Casper owners. Casper was named one of Fast Company's Most Innovative Companies in the World, and its eponymous mattress was crowned one of Time's Best Inventions of 2015.
