The 24-month gap between Essential Upsell & Cross Sell's and Aris Product Options, Variants's time-to-1,000 highlights how unevenly product-market fit landed across this add-ons set — the leader found its merchant audience early, while late-rampers took multiple years to reach the same review depth. For merchants comparing these apps today, slower-ramping apps may have closed the functionality gap but still operate on smaller review bases.
