Chronic allergy sufferers know well the daily discomfort of seasonal allergies and environmental allergies. They also likely know about allergy shots — the treatment that requires you to go into an office to get shots on a weekly or monthly basis. But there is a lesser-known treatment, allergy drops, that requires a bit less effort. Wyndly, a startup participating in Y Combinator’s current batch, aims to make allergy drops more accessible to people.

Before the pandemic, Dr. Manan Shah, an otolaryngologist (an ear, nose, throat doctor), would have his patients come in for an evaluation and then prescribe them personalized allergy drops to train their immune system to fight off allergy triggers.  When the COVID-19 pandemic hit, Shah, began treating his patients suffering from allergies via telemedicine. That went well so Dr. Shah and his cousin, Aakash Shah, took their idea to Y Combinator. They showed their idea was working well in Denver, Colorado but wanted help taking it nationwide.
