Creators pay for tools. Players pay for content. Arcanum takes a commission on every transaction — aligning platform revenue directly with creator success.
Arcanum is a structured creation engine for interactive, branching stories — combining a narrative design tool, a full game mechanic system, a live validation engine, and a built-in monetization layer in one platform. The $13.4B narrative games market is growing at 28% YoY with zero dominant creator-first tooling. Every existing tool forces creators into a binary: scripting languages for depth, or toy editors for accessibility. Arcanum eliminates this tradeoff through narrative-intent templates that convert story description into deterministic, testable, monetizable logic automatically — no code at any tier.
The business model mirrors proven creator economy platforms: a free tier with commission, professional subscription tiers, and a player marketplace. Revenue scales directly with creator success — Arcanum wins when creators publish and players pay. The moat deepens with every story published: creator graph data, player behavior patterns, and state transition analytics build a corpus that improves template accuracy, validation heuristics, and AI-assisted creation over time.
Three subscription tiers plus platform commission on all player transactions. Creator subscriptions provide recurring base revenue; commission income scales with total content volume and player engagement on the platform.

| Metric | Value | Notes |
|---|---|---|
| Blended ARPU | ~$22/mo | 60% Free (commission only) + 32% Pro ($19) + 8% Studio ($49). ARPU grows as creators publish more and commission income scales with story catalog. |
| CAC | $18 | Community-first acquisition: NaNoWriMo forums, itch.io, CoG communities, game jam partnerships. Near-zero paid media in Y1. |
| LTV (12-month) | ~$264 | 12-month average retention at $22/mo blended ARPU. Studio tier LTV significantly higher due to lower churn and team commitment. |
| LTV : CAC | 14.7:1 | Strong ratio enabled by low CAC (community-led acquisition) and sticky SaaS-like creator subscription with high switching cost. |
| Gross Margin | ~82% | Low COGS — cloud infrastructure, CDN, email. No per-user AI inference in MVP. No human review bottleneck. Scales cleanly. |
| Monthly churn target | 5% | Pro: ~4% (invested creators). Studio: ~3% (team commitment). Free: ~8% (pre-publish drop-off — addressed by guided onboarding). |
| Time to first publish | <14 days target | Key retention metric. Creators who publish their first story within 2 weeks have 3× 90-day retention. Onboarding optimized for this milestone. |
Arcanum's GTM is built on the insight that the early adopter is not a general consumer — it is a motivated, community-embedded fiction creator who has already tried and been frustrated by existing tools. Distribution is community-first; conversion is tooling-quality-first.
