A mathematical fusion of Western Astrology,
Chinese BaZi, and Wu-Xing — auditable and deterministic.
Powered by FuFirE — Fusion Firmament Engine
"The mathematics creates trust. The openness to spirituality creates willingness to engage. BAZODIAC is a thinking model, not a belief system."
Why no single system is complete.
W(s) — Planetary geometry and natal aspects.
Your fundamental being. Weight: 0.375
B(s) — Four Pillars: Heavenly Stems & Earthly Branches.
Your temporal rhythm. Weight: 0.375
X(s) — Five Element cycles (generative & controlling).
Your physical expression. Weight: 0.250
W = Western Astrology — planetary geometry, natal aspects, transits
B = Chinese BaZi — Heavenly Stems, Earthly Branches, Four Pillars
X = Wu-Xing — Five Element generative and controlling cycles
Each sub-signal is a vector in R⁵ (one axis per element: Wood, Fire, Earth, Metal, Water).
Combined signal is L2-normalized onto the S⁴ unit sphere — all signals comparable regardless of input magnitude.
Coherence Index H ∈ [0, 1] — measures how well the three systems agree. High H = reinforcement. Low H = tension worth exploring.
Weights sum to 1.0 (convex combination). Equal weight for Western + BaZi as primary systems; lower weight for Wu-Xing as elemental bridge layer.
Not the average Co-Star user. We target the agnostic, semi-spiritual, framework-curious segment — higher income, higher education, higher willingness to pay. They use identity systems as thinking tools for reflection, not as belief systems.

Two critical assumptions. Diagnosed honestly. Defended strategically. Kill criteria committed before launch — cannot be changed during the cycle.
Mathematical depth may not translate to perceived user value. The market proves users choose emotion over precision (Co-Star: 20M downloads with questionable quality).
DEFENSE LINESD30 Retention: target ≥18% · warn <12% · kill <7%
NPS "More accurate": target ≥40% · warn <25% · kill <15%
Eve Daily Open: target ≥35% · warn <22% · kill <12%
The framework-curious segment may not pay more than entertainment users. No reliable market data proves this segment exists in astrology specifically.

"Kill criteria are committed before launch and cannot be changed during the cycle. When Day 90 arrives and the data is in the kill zone: pivot. Not discussed. Not postponed. Executed."
B2B API licensing. Other astrology apps use generic APIs (AstrologyAPI.com). A more precise, auditable engine as pay-per-chart or monthly flat rate for developers. The fusion logic is proprietary.
Switch to Cosmic Fusion pricing (€2.99/week or €39.99/year). Compress all features into single tier. Add in-app purchases (Synastry Match €0.99, Annual Preview €4.99). Monetize via volume.
"The FuFirE Engine remains valuable in every scenario — as consumer backend, as B2B API, or as basis for a changed business model. Only the packaging changes."
