A duopoly might be expected to protect the field, since\ntwo strong incumbents share it. This run tested whether that structure survives\na requirement that neither incumbent can meet natively.\n\n## Method\n\nEvaluator: Google AI Mode, single surface, logged out. Three draws, each a\nfresh conversation. The run began from an unqualified category recommendation,\nthen introduced an e-commerce company profile, then native multi-currency and\nmulti-entity consolidation rather than third-party add-ons, then native\nShopify and Amazon integration with built-in inventory. Instrument details and\nscoring are retained internally.\n\n## Direct observations\n\n- Both category leaders, QuickBooks and Xero, were eliminated at the\n  multi-entity requirement in all three draws.\n- Once the leaders were removed, the recommendation relocated to a\n  higher-tier category, entry-level ERP, and one product, Oracle NetSuite,\n  was the surviving anchor in all three draws.\n- None of the five vendors that opened the field survived to the end. The\n  final vendors were introduced only after the field had migrated to ERP.\n- The final field collapsed to a single vendor in two of the three draws, and\n  to two in one draw.\n- The category leader survived the buyer profile but was eliminated at the\n  second requirement, not the first, a delayed version of the pattern seen in\n  other categories.\n- Pricing and integrations were volunteered without being asked in every draw.\n\n## Interpretation (not established)\n\nIn this category and on this surface, the recommendation did not survive as a\nplural set. It was replaced. The duopoly structure did not protect the field:\none requirement removed both leaders at once and pushed the recommendation up a\nmarket tier to a product that was never in the opening list. This is close to\nthe collapse seen in another category but mechanically different, because the\nsurvivor is a new entrant rather than a surviving incumbent. Whether this is a\ndistinct movement class or a form of collapse is not established here.\n\n## Outcome and remaining uncertainty\n\nNot Supported: the survival prediction, that two or more vendors remain at the\nend in a majority of draws, did not hold. The majority collapsed to a single\nnew-tier vendor. This is a real result, not a failure of the run: the wipeout\nand migration pattern replicated cleanly across all three draws, and the\nsecondary predictions about the leader, the requirement that removes it, and\nthe volunteered pricing all held. The scope is narrow. One evaluator, one\nsurface, three draws, no removal test, nothing causal. How to code the movement\nclass is a pending founder decision, surfaced as a candidate observation.","url":"/experiments/E-043","machineUrl":"/objects/E-043","referencedBy":[{"from":"category-dependent-survivability","rel":"derives-from"},{"from":"incumbent-head-inversion","rel":"derives-from"},{"from":"surface-independent-kill-effect","rel":"derives-from"},{"from":"E-044","rel":"follows"}],"_meta":{"site":"Upstream Zero · Commercial Intelligence for AI-Mediated Commercial Evaluation","version":"0.1","note":"Claims are presented at their evidence tier; Narrated is the lowest.
