Why Complement 1 Matters
For cancer patients, support often stops at the hospital doors. Complement 1 bridges that gap by providing continuous, personalized care beyond treatment rooms. Patients receive daily coaching tailored to their lifestyle, health risks, and emotional needs. These interactions are guided by coaches who combine clinical knowledge with a deep understanding of behavioral health.
This model doesn’t replace traditional treatment—it complements it. Hence the name: Complement 1.
By focusing on day-to-day improvements in nutrition, sleep, stress management, and physical activity, the platform helps reduce common side effects of cancer therapy while enhancing recovery and quality of life.
Real-Life Use Case: Jane’s Recovery Journey
Consider Jane, a 46-year-old woman undergoing chemotherapy. She experienced insomnia, anxiety, and extreme fatigue. After joining Complement 1:
- She received personalized meal plans to ease nausea.
- Her coach introduced simple breathing techniques for better sleep.
- Daily text check-ins helped her stay active and motivated.
Within four weeks, Jane reported better sleep, more energy, and fewer medication side effects—without needing additional clinical visits.
Why Investors Are Backing This Model
Complement 1’s business model taps into several strong trends:
- The growing global burden of cancer
- A shift to patient-centered care
- Increased focus on preventive and supportive healthcare
- Employer-driven wellness programs
By delivering measurable improvements and integrating with broader healthcare systems, the platform demonstrates potential to reduce healthcare costs while improving outcomes.

Using AI, the platform generates a tailored daily plan addressing lifestyle goals—from nutrition to sleep to mental health.
Step 3: Daily Coaching
Each patient is assigned a CoActive Coach, offering guidance via messaging, calls, and in-app tracking tools.
Step 4: Progress Monitoring
Patients’ data is tracked in real-time. Plans are adapted as patients progress, ensuring long-term adherence and meaningful results.
Data Privacy
All patient information is encrypted and managed in compliance with U.S. healthcare standards.
Potential Challenges
Like all healthtech ventures, Complement 1 faces hurdles:
- Gaining trust from traditional medical institutions
- Scaling human-led coaching without compromising quality
- Customizing care across diverse demographics
- Navigating evolving healthcare regulations
However, with a proven founder and strong investor backing, these challenges are being actively addressed.
