What it is
WorthSignal is a free, open-source customer analytics toolkit that turns Excel, CSV, or JSON data into segmentation, lifetime value, retention, and marketing ROI analyses. Its nine analysis areas include RFM targeting, customer equity, acquisition and retention budgets, Markov switching ROI, contractual retention, BG/NBD, BG/BB, and complaint recovery. The app reads XLSX, XLS, XLSM, CSV, and JSON files, suggests column mappings, and lets users adjust each mapping without changing the uploaded file. Results can be exported as Excel or JSON. In local mode, analysis runs in memory on the user's computer; the project says it does not intentionally send uploaded customer data to its maintainer or a third-party API. Hosted files are processed by the selected server, whose operator is responsible for access, logs, retention, and privacy obligations. WorthSignal requires Python 3.10 or newer and offers launch guidance for Windows and Mac, terminal use across operating systems, and Docker deployment. Its documented methods are described as classic and deliberately simple models. The project uses the AGPL-3.0-or-later license, with commercial use subject to its conditions.
