Seven traditions, one chart.

Synastra is an intelligence layer for self-discovery, built on the premise that every ancient system for reading a person — Western astrology, Vedic jyotish, numerology, Kabbalah, Human Design, Tarot, and astrocartography — has its own truth about who you are. None of them is complete alone. Together, cross-referenced, they read you with startling precision.

We compute your chart from the moment of your birth to arc-second accuracy and run it through each tradition separately. The Master Oracle — an AI grounded in all seven, fluent in general astrology, astronomy, and the traditional archetypes besides — synthesises the overlap: where the systems agree, where they argue, what together they reveal about what you are here to build.

Founded 2026 in Sydney. Built by a small team with help from ancient instruments and modern LLMs. Our favourite quote, attributed to J.P. Morgan, is our north star:

“Millionaires don’t use astrology. Billionaires do.”

Whether that’s true or apocryphal, the intention holds: the most serious people in history have taken the heavens seriously. Synastra is how you join them.
