Northwind
Overview
Northwind is a tele-dermatology start-up changing how chronic skin conditions Psoriasis and Atopic Eczema are treated.
We connect 31 million American patients to specialists in under 12 hours, and provide a tailor-made treatment plan with our proprietary line of clinically tested vegan OTC and Rx products.
Patients register and go through our digital questionnaire, uploading pictures of their affected skin. In under 12 hours the patient receives their own specialised dermatologist who then decides the correct treatment plan required - with monthly checkpoints where the plan is adjusted based on patient feedback and results.
Today, thousands of users rely on, and love Northwinds proprietary Swedish formulas. The company is led by a patient suffering from 20 years of severe Psoriasis.
