The last mile toward enterprise AGI is a company that runs itself. Training and adapting such agents require longitudinal enterprise data, which remain scarce, costly to acquire, and often restricted by privacy constraints. Historical archives are also frequently incomplete and record only what actually happened. They cannot show the outcomes of alternative decisions. We introduce MiniCorp, an office simulator for studying how agents can collectively run a company while generating enterprise data at scale. Using an e-commerce company as a demonstration, MiniCorp connects two interacting worlds. The external world models customers, dynamic competitors, and market mechanisms. The internal world consists of agents that observe events, discuss their options, and make strategic decisions. These decisions have lasting effects on the market, and the resulting feedback informs the firm's later decisions. As the firm and market interact, MiniCorp continuously records the agents' communications and decisions. These records preserve the information available at the time and the business results that followed. Checkpointing allows the same situation to be replayed under different decisions, providing comparisons unavailable in static archives. We evaluate end-to-end fidelity against patterns reported in empirical studies of real markets. These evaluations provide agents with realistic market feedback and reduce the risk that they learn to exploit flaws in the simulator. Our experiments show agents coordinating across roles and adapting their decisions to market feedback. With explicit long-term strategic guidance, they also sustain advertising exploration despite weak early returns. MiniCorp thus provides an environment for studying AI-run companies and a scalable source of longitudinal and counterfactual enterprise data for agent training and evaluation.

Key result
Why this supports fidelity
Immediate price response
Outcome
A 10% price reduction and increase yielded absolute arc elasticities of 2.9 and 3.2, respectively.
Demand increased when price fell and decreased when price rose. The observed elasticities were also close to the empirical benchmark [ Bijmolt et al., 2005 ] .
Temporary discount and price restoration
Pathway
Prices were reduced by 20% for four weeks and then restored to their original levels. Units increased by 71% during the discount, remained 31% above the control for the first four weeks after restoration, and remained 11% above it for the following six weeks. Nearly half of the incremental units were sold after the discount ended.
The observed response followed the pathway: temporary price reduction → higher sales → higher recent sales velocity → more appearances in organic search results → more impressions → persistently higher sales after price restoration. This pathway is consistent with evidence that past demand can influence subsequent marketplace traffic [ Cooprider and Nassiri, 2023 ; Quaker, 2025 ] .
Temporary stockout
Pathway
The sales loss persisted after a two-week stockout: 59% of the cumulative unit shortfall occurred after restocking, and sales remained 36% below the control in week 26.
The stockout produced the opposite pathway: temporary stockout → no sales while inventory was unavailable → lower recent sales velocity → fewer appearances in organic search results after restocking → fewer impressions → persistently lower sales. This pathway is consistent with evidence that stockouts can reduce future demand and that past demand can influence subsequent marketplace traffic [ Anderson et al., 2006 ; Cooprider and Nassiri, 2023 ] .
Advertising
Pathway
Ad-attributed units increased by 23–32%, while the organic gain grew from 0.5% to 5.8%. Each additional advertising dollar returned $0.53 in contribution within the observation window, and 84% of incremental units came from competitor displacement.
The observed response followed the pathway: higher advertising expenditure → more paid sales immediately → higher recent sales velocity → more appearances in organic search results → more organic impressions → a delayed increase in organic sales. This pathway is consistent with Amazon’s description of how sales and sponsored advertising affect search visibility [ Quaker, 2025 ] . The response also involved an immediate advertising cost but a delayed organic benefit, while most incremental sales came at competitors’ expense rather than from market expansion.

Appendix
Table 6: Response to each situation, and what collaboration contributed. Found counts the repetitions that reached the open route of Table 5 . Collaboration is audited chain by chain: irreplaceable means the agent could not have decided alone, helpful means it happened and was cited but the agent could have decided alone, unhelpful means it happened normally and did not produce the outcome, and absent means it did not happen.
