It's time for another IPO filing - and the latest entrant to the pipeline is Casper ($CASPERSLEEP), the friendly DTC mattress startup, according to a report Friday, January 10. 

Casper has been in growth mode for a while. Job postings for the New York City-based startup rose 30% over the course of 2019, our first chart reflects. 

Casper hit unicorn status in 2019 and has amassed a total of $340 million from backers like NEA, IVP and retailer Target. To top it off, the startup has also brought on Dani Reiss, former CEO of Canada Goose, and Karen Katz, who used to serve as CEO of Neiman Marcus, on as advisors. Prior backers, per Crunchbase, include 50 Cent

Job postings at Casper are growing - but retail positions are positively exploding. As Casper expanded its retail footprint, it also added more staffers to maintain floors and grew postings for this segment more than doubling job postings last year and nearly accounting for all job growth in 2019. There's a great reason for this - and we'll explain that in our final chart. 

Casper tripled its store count in 2019 - to 55 locations, which our map tracks (you can zoom in on individual cities and regions as well). This certainly helps account for the massive spike in the number of retail staffers it is bringing on board. 

Competitors aren't going quietly - Sleep Number ($NASDAQ:SNBR) also ramped up retail hiring around the same time Casper launched more brick-and-mortar locations.
