AI PM Case Study
Digital Therapy Companion
(Transfer Learning + HIPPA)
Disclaimer: This case study is a conceptual project created to during my AI Product Architecture study. It does not reflect proprietary information or strategies from any specific organization.
Problem Statement
Recognizing the challenges patients face in maintaining therapeutic momentum between sessions and clinicians' limited visibility into patient progress, this project seeks to bridge these gaps. By integrating a fine-tuned LLM model + HIPAA transparency, we aim to provide continuous, personalized assistance, enhancing the therapeutic journey for both patients and clinicians.
Solution Overview
Designed a Digital Therapy Companion leveraging Transfer Learning and Fine-Tuning of a pre-trained LLM model to deliver personalized, context-aware therapeutic support. The model is fine-tuned using:
• Domain-Specific Datasets: Tailored datasets focusing on mental health, cognitive behavioral patterns, and therapeutic strategies.
• User Interaction Logs: Anonymized conversational data and self-reports to enhance contextual understanding and personalize responses.
• Human-in-the-Loop (HITL) Framework: Incorporating clinician oversight for feedback, verification, and training data labeling to enhance the model’s reliability and safety.
• Feedback Loops: Continuous retraining using new inputs to maintain relevance and improve model performance over time.
• HIPAA Compliance Measures: Ensuring data privacy and security throughout the fine-tuning process.
Target Users & User stories

AI & Cognitive System Integration
Go-to-Market (GTM) Strategy
Initial Phase: Clinician-Focused (B2B2C)
• Direct outreach to private practice therapists, group practices, and behavioral health networks.
• Partner with digital mental health platforms (BetterHelp, Headspace Health) to integrate.
• Offer free clinician dashboard & analytics tools to drive buy-in.
• Patient acquisition via clinician referrals–pre-vetted by therapist.
Scale Phase: Employer & Payor Partnerships
• Target self-insured employers via corporate wellness programs.
• Emphasize improved adherence, reduced absenteeism, and proactive intervention benefits.
• Bundle with broader employee mental health offerings (EAPs, virtual therapy networks).
• Pilot outcomes-based pricing–lower per-member cost if adherence targets are hit.
Long-Term Play: Direct-to-Consumer (DTC) (Optional)
• Carefully tested DTC version for mild-to-moderate mental health needs (non-acute users).
• Leverage partnerships with mental health influencers, patient advocacy groups, and public health campaigns.
• Offer freemium model–basic journaling & check-ins free, premium AI insights & clinician syncing for subscription fee.
• DTC is expensive, but could unlock viral growth if the product earns trust.

Trade-offs Considered
Challenge
Approach
Balancing transparency with privacy
Patient-first design: full data preview & opt-in sharing controls.
Avoiding over-medicalization
Focused on gentle guidance, not diagnostic labels — supportive, not clinical.
Engagement fatigue Index
AI detects declining engagement and fatigue index and adjusts touchpoint frequency and tone.
Clinician burden vs. insight value
High-level summaries only — clinicians get actionable trends, not raw data overload.
