More like parallel development. Cell Cycling is selling an updated XShifter, a Kickstarter product that was already prototyped by mid-2016. I believe Archer's D1X came later. They both fill the same niche, but XShifter appears to a better product (though the original Kickstarter backers would argue that Archer is a better company. Despite the logo on the site, however, Cell Cycling is not affiliated with XShifter's Kickstarter campaign.)
