Strategy Arena Lab

Lab subscriptions

Builder for your reports and versions. Operator for supervised research.

Monthly or yearly billing · cancel online · no audit required

A Lab software subscription, not a premium site. Free keeps the first proof. Builder keeps every useful report. Test for free. Keep your work. Supervise an AI.

Payment never improves the verdict, holdout or uncertainty evidence. Cancel online at any time from your account. See the CGV and the privacy policy.

Arena Credits are not sold and never required to subscribe. Optional AI-credit packs are a separate product.

A public Lab Report publication is a separate one-time purchase from your report library; the Strategy Passport stage above stays unsold.

Need one independent audit, not a subscription?

Survival Audit costs 9.90 EUR once for one private report. It is a separate purchase, not included in Builder or Operator, and is never required to subscribe.

Upgrade for a workflow, never for a better verdict

A subscription never changes the verdict. All plans use the same scientific rules. You pay for workspace or research capacity, never a promise of profitability.
