A startup building hardware - not to mention advanced image-tracking, autonomous navigation, (hopefully) hazard avoidance, which are hard problems - would in my estimation have more staff doing engineering and manufacturing, rather than design and sales.
Is this a reasonable team arrangement? Am I underestimating the skills of their technical staff, are they outsourcing engineering, or are they using a preexisting plaform? Or am I underestimating the importance of design and sales (which have certainly produced and brought to my attention a gorgeous Kickstarter page)?
