About Sunflower

Sunflower is building an AI-native telemedicine clinic for addiction. There are over 18,750 patients on a waitlist for Therapy or Meds, representing $153M worth of TAM just waiting to be served. We started by launching Sunflower Sober, the first AI Sponsor for addiction which grew to 100 MAU in less than 6 months and currently driving about $1.5M in run-rate worth of subscription app revenue. Sunflower Sober is currently pacing to add over 800,000 new users a year which means we are growing literally faster than Alcoholics Anonymous. We have built one of the largest and most deeply loved brands within sobriety, and now we are building the clinical services underneath this brand to better fulfill on our mission & serve Medicaid who spends over $30B a year on SUD services. Sunflower is founded by Koby who previously led Growth at Rupa from $5M to $75M/year. Our team includes clinical leaders (MDs / LPCs) from the Mayo Clinic, Choose Your Horizon, & Charlie Health.

    Why hasn’t there been a better product built for addiction yet? I have no idea.

    Why hasn’t there been a better product built for addiction yet? I have no idea. 🤷🏻‍♀️ But Sam & the rest of our worker bees are busy creating something magical. If you’re ready to stop drinking, smoking, vaping, gambling, or ANY destructive behavior… come follow along. :)

    Headspace getting acquired for $300M is EXACTLY why we are launching the Sunflower Clinic Don't cancel me: Consumer Health Apps don't create venture scale businesses.
