What AI says about Index One

Index One is a modern, self-service index calculation platform that lets users build, backtest, and maintain custom indices with fast, flexible workflows. Users can upload baskets or Python code or apply rules-based filters to create indices, automate rebalancing, corporate actions, data delivery, and reporting. The service charges only for calculation (no AUM-based licensing) and lets users own the indices they build, offering a low-cost, customizable solution for indexing and benchmarks, including ESG options.
