# Chief Data Officer Advisor

Strategic data leadership for startup CDOs and founders without one. **Four decisions, no surveys:**

1. **Can we train our model on this data?** — origin × consent × use-case matrix
2. **Warehouse, lakehouse, or mesh — and what do we build vs buy?** — stage-driven architecture
3. **What is our customer data worth?** — strategic value + M&A multiplier + productization paths
4. **What data role do we hire next?** — stage-to-role map, centralize-vs-embed trigger

This skill does **not** cover tactical data engineering. For schema design, observability, query optimization, RAG, or ML platform implementation, see `engineering/database-designer/`, `engineering/observability-designer/`, `engineering/data-quality-auditor/`, `engineering/sql-database-assistant/`, `engineering/rag-architect/`, `engineering/llm-cost-optimizer/`.

## Quick Start

```bash
# Audit data sources for AI training eligibility
python scripts/ai_training_data_audit.py                              # uses embedded sample
python scripts/ai_training_data_audit.py path/to/sources.json

# Pick data architecture + build-vs-buy + sequencing
python scripts/data_product_strategy_picker.py                        # uses embedded Series A SaaS
python scripts/data_product_strategy_picker.py path/to/profile.json

# Value the customer data corpus + productization viability
python scripts/data_asset_valuator.py                                 # uses embedded B2B sample
python scripts/data_asset_valuator.py path/to/corpus.json
```

## Key Questions (ask these first)

- **What decision does this data drive?** (If none, why are we collecting it?)
- **What's the consent provenance of every source we want to train on?** (TOS-only is not the same as explicit opt-in.)
- **Who are the internal data consumers, and how many distinct domains do they span?** (Drives centralize-vs-embed and warehouse-vs-mesh.)
- **In an M&A scenario, is our data a moat or a liability?** (Customer carve-outs in MSAs can flip the answer.)
- **Are we hiring an analytics engineer or a data scientist next?** (They solve different problems; founders confuse them.)
- **Have we run an anonymization audit before any external sharing?** (k-anonymity ≥ 5 is the floor, not the ceiling.)
