Meet Brynn Putnam. The executive director and founder secured $ 3 million in venture capital the same day she gave birth to her son to fund her technology-based fitness company, MIRROR. In the summer of 2020, Putnam sold MIRROR to Lululemon for $ 500 million. The pandemic was good for business. MIRROR ads are being displayed on the New York subway, broadcast on television, and clogging social media channels. But selling a business for half a billion dollars is only a small part of its history, and frankly not even the most interesting. There are three numbers to note in this story. $ 15,000: The amount Brynn had in her savings when she quit ballet. $ 3 million: your first outside investment. $ 500 million: The amount she sold MIRROR for in 2020. Brynn Putnam built a business worth half a billion dollars in just two years.
