[ ] **[must-have]** An agent can query customer data and create or activate audiences end to end through documented APIs or MCP — no dashboard in the loop - [ ] **[must-have]** An agent can manage the pipeline itself — create sources and destinations, wire streams, inspect deliveries — through a documented API or MCP server - [ ] **[should-have]** Describe an audience in natural language and AI builds the segment definition for review, grounded in my actual schema - [ ] **[should-have]** AI decisioning agents pick messages, timing, and channels per customer autonomously within guardrails I set, with measurable lift ## Audiences activation - [ ] **[must-have]** Build audiences from traits and behavior in a visual builder — no SQL required — and see estimated size before activating - [ ] **[should-have]** Audiences sync to ad platforms and engagement tools continuously, with membership entering and exiting in near-real-time - [ ] **[should-have]** Computed traits and predictive scores (LTV, churn or purchase propensity) are calculated on profiles and usable in targeting ## Automation depth - [ ] **[must-have]** Define rules that trigger actions automatically on events - [ ] **[should-have]** Perform bulk operations across many items at once - [ ] **[should-have]** Schedule recurring jobs or workflows - [ ] **[nice-to-have]** Version, review, and roll back my automations ## Destinations integrations - [ ] **[must-have]** Route events to a large catalog of documented destination integrations with per-destination mapping and filtering ## Event collection - [ ] **[must-have]** Collect events from web, mobile, and server apps through official SDKs that implement a documented tracking spec (track, identify, page) -

[ ] **[must-have]** Export all of my data in open formats and leave - [ ] **[must-have]** Self-host the core product - [ ] **[should-have]** Do everything through the API that I can do in the UI - [ ] **[should-have]** Read the product's source under an open license ## Pipeline observability - [ ] **[should-have]** Watch events flow live and diagnose delivery failures per destination — debugger views, delivery metrics, and alerting ## Privacy consent - [ ] **[must-have]** User consent is captured and enforced across destinations — opt-outs and consent categories are honored downstream automatically - [ ] **[should-have]** Process user deletion and suppression requests (GDPR/CCPA) and have them forwarded to connected destinations - [ ] **[should-have]** Control PII flow per destination — hashing, masking, and field-level filtering of sensitive attributes ## Privacy posture - [ ] **[must-have]** Prevent my data from being used to train AI models - [ ] **[should-have]** Choose where my data is stored (region/residency) - [ ] **[should-have]** Control data retention and deletion - [ ] **[should-have]** Opt out of telemetry and usage tracking ## Replay portability - [ ] **[should-have]** Replay archived events into a new destination or backfill history when a tool is added or a pipeline breaks ## Transformations quality - [ ] **[should-have]** A tracking plan or schema is enforced — violating events get flagged, blocked, or quarantined instead of silently corrupting downstream data - [ ] **[should-have]** Transform, filter, and enrich events in-pipeline with custom code or functions before they reach destinations ## Warehouse native - [ ] **[must-have]** Raw events and profiles land in my own warehouse or lake (Snowflake, BigQuery, ClickHouse, S3) on a schedule I control - [ ] **[should-have]** Run warehouse-native: define models and audiences on tables already in my warehouse and activate them without re-collecting the data (reverse ETL) --- Source: https://ultrametric.ai/productarena/arena/customer-data-platforms (evidence-graded verdicts for 5 products) · methodology: https://ultrametric.ai/productarena/methodology
