Co-Star
The hyper-personalized, social experience bringing astrology into the 21st century.
What is Co-Star?
WHAT IS ASTROLOGY? Astrology is a system based on the exact positions of the stars and planets in our sky, helping humans understand themselves, their friends, and the world around them for 2,500 years.
HOW DOES CO-STAR WORK? Co-Star uses NASA data and proprietary technology to generate hyper-personalized horoscopes. By building a complete map of the sky at the moment you were born, always knowing exactly where the stars are and updating in real time, Co-Star gives you the tools to make sense of the world.
WHAT IS CO-STAR’S FOUNDING STORY? Banu Guler discovered astrology in elementary school, where she would thumb through magazines to find her horoscope. It’s long been a tool she’s utilized to make deeper and more meaningful connections with people her in life.
A few years ago, when a good friend of hers had a baby, she made a full book-length reading of the baby’s natal chart. When she presented the gift at the baby shower, the other guests fawned over it, asking if she could make one for them and their children. She realized she was onto something.
For over 2,500 years humans have utilized astrology as a way to understand themselves, their friends, and the world around them. By 2017, millions of people were using astrology in their everyday lives, but that there wasn’t a modern astrological tool to make the experience digital, personal and social. So in 2017, Banu Guler, Ben Weitzman, and Anna Kopp launched Co-Star, the hyper-personalized, social astrology app bringing astrology into the 21st century.
HOW POPULAR IS ASTROLOGY? First, astrology has been used by humans for thousands of years, and belief in astrology has actually been consistent for the past 50 years, about half of young people and a third of adults. Now, the reason there's been so much written recently about astrology is because all that interest has moved online. People now have social tools, like Co-Star, to share and communicate via astrology and that's simply never been available before.
