We adopt a network effects (NEs) perspective to conceptualize AI strategies, highlighting the context’s specifics. argue that nascent strategies’ success depends on data NEs: companies establishing functional “running system” capitalize these effects. However, this presents challenge known as cold-start problem (CSP), which involves initiating and accelerating virtuous...
