Both are important: product development + marketing. Mr commonsense once thought that code was all-important, and now, it seems, makes the opposite error. New technology can and does make a difference. Edison focussed on technical contribution, so did Hewlett Packard (once), and google began with technical innovation in a saturated market. Though to be fair, it's the technology that makes the difference (the concept, the algorithm, the insight, the approach) not the code per se.
