The AI companion market exhibits extreme concentration: the top 10% of apps capture 89% of revenue. Understanding the five layers of this stack reveals where value accumulates—and where it’s vulnerable.
These companies provide the underlying intelligence that powers companion experiences.
Strategic Insight: The acqui-hire playbook has transformed this layer. Google paid $2.7B for Character.AI founders. Microsoft paid $650M for Inflection’s team. These aren’t traditional M&A—they’re talent and IP acquisitions designed to bypass regulatory scrutiny.
Layer 2: Dedicated Companion Platforms
Purpose-built applications for emotional connection, relationship simulation, and personal support:
Character.AI: 20M MAU, $193M Series A. Founders departed to Google—now a “licensing shell”
Replika: 25-30M users, $11M bootstrapped. 60% of premium users report romantic relationships with AI
Xiaoice: 660M users across China/Japan/Indonesia. $2B valuation. The quiet giant
Pi (Inflection): $1.525B raised, then absorbed by Microsoft
Layer 3: Mental Health AI
Woebot represents the clinical path—pursuing FDA approval. Wysa operates in the “wellness” space between consumer and clinical.
ElliQ achieved remarkable outcomes: 95% of users report reduced loneliness. But Moxie shut down in December 2024—hardware margins and regulatory complexity proved insurmountable.
Layer 5: Emotional AI Infrastructure
Hume AI represents horizontal infrastructure—emotion detection any application can integrate. This is the picks-and-shovels layer.
Strategic implication: This will consolidate into a few massive consumer surfaces, vertical specialists with defensible niches, and infrastructure layers supplying “emotional capability.”
