+# INVESTOR BRIEF: Spark Platform
+
+> **BLUF**: Spark is a multi-tenant content scaling platform that generates location-targeted SEO articles using spintax permutation and Cartesian pattern matching. Current capacity: 50,000+ unique articles per campaign configuration.
+
+---
+
+## 1. Platform Function
+
+Spark automates SEO content production at scale. The system:
+1. Ingests buyer personas (Avatars), location data, and content templates
+2. Computes Cartesian products of location × persona × offer variations
+3. Generates unique articles with geo-specific and persona-specific content
+4. Manages multi-site content distribution with scheduling controls
+
+**Core Problem Solved**: Manual SEO content creation produces ~2-5 articles/day. Spark produces 100-500 articles/hour with equivalent uniqueness and targeting precision.
+
+---
+
+## 2. Technical Stack
+
+| Layer | Technology | Version | Purpose |
+|-------|------------|---------|---------|
+| Frontend | Astro | 4.7 | SSR + Islands Architecture |
+| UI | React | 18.3 | Interactive components |
+| Backend | Directus | 11 | Headless CMS + REST/GraphQL |
+| Database | PostgreSQL | 16 | Primary data store |
+| Extensions | PostGIS | 3.4 | Geographic queries |
+| Cache | Redis | 7 | Session + job queue backing |
+| Queue | BullMQ | - | Async job processing |
+| Deployment | Coolify | - | Docker orchestration |
+
+**Infrastructure**: Self-hostable via Docker Compose. No external SaaS dependencies.
+
+---
+
+## 3. Data Assets
+
+### 3.1 Location Database
+| Dataset | Count | Source |
+|---------|-------|--------|
+| US States | 51 | Census data |
+| US Counties | 3,143 | Census data |
+| US Cities | ~50 per county | Population-ranked |
+
+### 3.2 Intelligence Assets
+| Asset Type | Description | IP Value |
+|------------|-------------|----------|
+| Avatar Intelligence | 10+ buyer personas with psychographics | Proprietary |
+| Wealth Clusters | 5+ economic profile groupings | Proprietary |
+| Spintax Dictionaries | Word/phrase variation libraries | Proprietary |
+| Cartesian Patterns | Title/hook formula combinations | Proprietary |
+| Offer Blocks | 10+ promotional templates | Proprietary |
+
+---
+
+## 4. Capacity Metrics
+
+### 4.1 Theoretical Maximum
+```
+10 Avatars × 10 Niches × 50 Cities × 10 Offers = 50,000 unique articles
+```
+
+### 4.2 Practical Campaign
+```
+2 Avatars × 3 Niches × 10 Cities × 2 Offers = 120 articles
+```
+
+### 4.3 Generation Speed
+| Operation | Throughput |
+|-----------|------------|
+| Headline permutation | 1,000/second |
+| Article assembly | 100-500/hour |
+| Queue processing | Configurable batch size |
+
