Cover image for  Full client engagement pipeline demonstrated
 Full client engagement pipeline demonstrated on fictional Series A SaaS data: 90,950 CRM rows, 1,025,447 Stripe  transactions, 115,500 QuickBooks invoices, 200 enterprise contracts — the exact profile of a typical new            engagement.                                                                                                                                                                      Five stages on one machine. No cluster. No cloud database fees.                                                         Stage 1: Ingest dirty data from CRM, Stripe, and QuickBooks exports.                                                Stage 2: Audit — quality scores, grime map, null analysis.  Stage 3: Clean — DuckDB SQL transforms, Parquet out.                                                                Stage 4: Analyse — 5 business queries, anomaly detection.                                                           Stage 5: RAG — embed, index, query across documents.                                                                                                                                                                                    Every stage runs inside DuckDB on a single workstation. This is the pipeline your data goes through on every        engagement.
