The tills have been ringing at mining software company, K2fly, with annual recurring revenues from just one of its software offerings, “RCubed”, almost doubling the annual target of $500,000 in just six months, with $900,000 a year now contracted annually for RCubed. The latest numbers come only weeks after the Perth based ASX-listed company signed a five-year software provision contract with mining goliath, Rio Tinto.
