What it is: Casper was founded to simplify the process of getting a mattress. Instead of a traditional mattress you'd buy at Sleepy's, Casper stuffs a big, fluffy mattress into a box and delivers it right to your door. In New York City, Casper says it'll deliver your mattress in two hours. Casper's mattresses come in six sizes and cost between $500 and $950 with a 10-year warranty. Casper told Business Insider the company was profitable on its first day of business, doing $1 million in sales in its first 28 days.

Launch date: Casper launched in April.

Funding: In January Casper raised a $1.9 million round of seed funding from QueensBridge Venture Partners, Correlation Ventures, Crosslink Capital, Vaizra Investments, Lerer Hippeau Ventures, and Norwest Venture Partners. In August, Casper raised $13.1 million in a Series A round of funding from Kevin Colleran, Slow Ventures, Vaizra Investments, Crosslink Capital, Norwest Venture Partners, Cendana Capital, Silas Capital, Consigliere Brand Capital, SV Angel, A-Grade Investments, Lerer Hippeau Ventures, and New Enterprise Associates.
