StaffJoy (<a href="https:&#x2F;&#x2F;www.staffjoy.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.staffjoy.com&#x2F;</a>) are using Julia for staff schedule optimization, and a large multinational is using it for train schedule optimization. Its also in use (at least on a trial basis) in the financial sector.<p>It&#x27;d still be a fairly large risk to develop something built-to-last on Julia at this point, so not really the best time for most companies to jump in unless something about Julia really solves a problem they are having.
