Avenor is a web-based, AI-assisted decision-support platform for business leaders. It helps teams frame consequential choices, assemble relevant company context and evidence, compare alternatives, and review recommendations, assumptions, risks, uncertainties, and information gaps. Leaders record the decision they adopt separately from AI-generated analysis, then assign an owner, next action, target date, review date, and success criteria. At review, teams compare observed results with expectations, document lessons, and retain decision records for future use. Avenor is intended for founders, CEOs, general managers, and functional leaders considering product, market, investment, operations, hiring, pricing, customer, and risk decisions. Teams provide context and outcome information themselves; the product does not automatically sync external tools, execute decisions, or monitor KPIs.
