About Ream
Ream is an innovative online mental health service dedicated to delivering effective and affordable support for adults with ADHD. The company faced challenges with low user retention and engagement using text-based tools and sought a solution that would add emotional nuance and personalization to its interactions.
Recognizing that voice interactions feel more natural and empathetic, Ream set out to transform its coaching approach. Hume’s EVI has been a game-changer for Ream, enabling the company to deliver a coaching experience that truly resonates with users.

Integrating Hume’s EVI
Ream integrated Hume’s EVI to enable daily 5-minute AI coaching calls via Twilio’s outbound phone calling API. Hume’s EVI transformed Ream’s coaching experience by adding:
-
Empathic Conversations: Hume’s EVI brings human-like voice interactions to life. For instance, when a frustrated user exclaimed, “I’ve called a thousand times!” the system responded with genuine empathy, transforming frustration into connection.
-
Memory and Personalization: The system remembers user habits and preferences, creating deeply personalized interactions. One user was delighted when EVI recalled a past conversation, saying, “Wow. You remember walking? Oh, that’s so cute. You remember me walking?”
-
Ease of Implementation: Hume’s EVI integrates seamlessly via Twilio’s outbound phone calling API, allowing Ream to implement a dynamic voice solution without significant overhead or development hurdles.”

The integration of Hume’s EVI has delivered transformative results for Ream:
-
2x Higher User Engagement: Voice-based coaching calls powered by EVI are far more engaging than traditional text-based systems, doubling daily active users by making the coaching experience less effortful and more enjoyable.
