Ancient Wisdom. Modern Intelligence.
Rimfactory is a cultural intelligence company that applies vector search, retrieval-augmented generation, and multi-model AI validation to classical Eastern wisdom systems — starting with Korean Four Pillars (사주).
Computational Astrology at Scale
In an age of uncertainty, billions seek guidance from astrology. But most services offer surface-level readings based on crude categorizations. We believe millennia of accumulated pattern recognition deserves rigorous computational analysis. Rimfactory bridges 2,000+ years of Eastern metaphysical theory with retrieval-augmented AI — every reading grounded in classical source texts, every claim verifiable.

Why We Can't Be Replicated
Classical Theory RAG Engine
562 passages from 5 foundational texts (滴天髓, 穷通宝鉴, 子平真诠, 渊海子平, 格局论命) — vectorized into 1,536-dimensional embeddings and matched to each user's birth chart in real time via cosine similarity search. Not a lookup table — a live retrieval-augmented generation pipeline.
RAG + Multi-LLM Pipeline
Classical passages injected into prompts via vector search → Gemini (interpretation) + Claude (verification), 5-stage fallback achieving 99.9% uptime. Each reading cites specific classical sources with similarity scores — verifiable, not hallucinated.
Domain-Specialized Architecture
Purpose-built saju calculation engine (만세력 calendar + solar time correction), custom embedding pipeline, and 6 months of prompt optimization across 3 languages. The stack is not reproducible by calling a generic API.
Data Compound Effect
More users → better AI quality → more users. Time compounds our advantage into an ever-widening gap.
A $14B+ Market, Ripe for Disruption
The global astrology market exceeds $14 billion and is accelerating online. Japan alone is a ¥1 trillion market transitioning from offline to digital. Existing services are limited: Western astrology offers only 12 types, Korean saju apps are Korean-only with dated UIs, and subscription fatigue is driving users away from monthly-fee models. Rimfactory enters with a one-time payment model, multilingual support, and AI precision that no incumbent offers.
