Rivvn helps cancer patients and survivors understand their treatment, track their progress, and make informed decisions in partnership with their oncology team. Built with AI that works for you, never on you.
The future of cancer intelligence starts here.
Be among the first to experience Rivvn when we launch in the coming months. We’ll send you early access details by email.
The 2 AM question about whether a supplement is safe with your chemo. The lab result you can't decode on a Friday night. The new symptom that doesn't justify a call but won't leave your head. The appointment you'll wait six weeks for — and the six weeks of decisions you'll make before you get there.
I'm Chris. I'm a Stage 4 Non-Hodgkin Lymphoma survivor, and I lived those nights. I built Rivvn for the time between appointments — and for everyone walking this path.
“Oncologists treat the disease. Rivvn supports the life around it.”

Here 24/7, 365 days a year — for patients, survivors, caregivers, and veterans.
Currently fighting cancer
Navigate treatment with confidence — supplement safety during chemo, the latest research for your specific cancer, and people on the same regimen.
Post-treatment and thriving
The fight doesn’t end when treatment does. Long-term monitoring, recurrence prevention, and a community that understands what comes next.
Proactively reducing your risk
Evidence-informed decisions about nutrition, supplements, and screening — especially if you have a family history or genetic predisposition.
Walking beside them
Caregivers carry the appointments, the research, and the worry — often invisibly. Rivvn gives you one place to understand, track, and ask.
I'm a U.S. Army veteran, and I'm service-connected. I know what it means to navigate VA and civilian care at the same time — and I know service can carry exposure-related cancer risks many veterans are only now learning about. Rivvn is built to work alongside both systems, with the same always-on intelligence between every appointment.

Founder · Stage 4 Cancer Survivor · Service-Connected Army Veteran
In November 2016, I was diagnosed with stage 4 cancer and completed chemotherapy as my first-line treatment. In the years since, I've combined conventional survivorship care with evidence-based integrative approaches — nutrition, movement, biomarker tracking, and mind-body practices — to support long-term health.
After navigating the information gap between oncology appointments and managing complex decisions about treatment, supplements, and integrative approaches alongside my care team, I built the cancer intelligence platform I needed. With 25 years of software architecture and engineering experience, Harvard Medical AI certified, and an Army service-connected veteran, I knew this problem could be solved.
Rivvn exists to help cancer patients and survivors make informed decisions in partnership with their healthcare teams — whether their path is primarily conventional, integrative, or somewhere in between. Rivvn is also as much for the people standing beside the patient as it is for the patient.
Join My Mission →Cancer survivors deserve tools that respect them. Here's how we built Rivvn to earn that trust from day one.
Rivvn was built by a stage 4 cancer survivor who needed tools that didn’t exist. Every feature is shaped by lived experience — the loneliness, the information overload, the late-night research, the hard conversations with doctors. Rivvn is the tool I wish I’d had.
— Chris Kennedy, Founder
Your health information is sacred. We collect only what’s needed, encrypt everything, and give you control over your data. We never sell it. We never use it to train third-party AI models. We never share it with advertisers, insurers, or employers.

Rivvn pairs a personal cancer research copilot with seven specialized AI helpers that quietly do the work — scanning new research on your chemotherapy regimen, checking supplement interactions with your medications, matching clinical trials, tracking your symptom patterns, and surfacing what matters most. Like a research team that never sleeps, working only for you.
Your personal cancer research co-pilot. Ask any question about your chemotherapy regimen, immunotherapy response, radiation side effects, supplement safety, or treatment options — and get personalized, cited answers grounded in your specific cancer profile. Unlike ChatGPT, the Copilot knows your diagnosis and stage, cross-references your medications against every supplement, cites PubMed studies and NCCN guidelines, and has oncology-specific safety guardrails.
Every answer is personalized to your cancer profile and grounded in real medical literature — never hallucinated.
Continuously scans PubMed, JAMA, and Lancet Oncology for new studies relevant to your specific cancer type, stage, and treatment. Pushes personalized insights when research matches your profile.

“Rivvn doesn't replace your oncologist. It makes every conversation with your oncologist smarter.”
Rivvn was built by a stage 4 cancer survivor for every kind of cancer journey.
Whether you're newly diagnosed, in active treatment, in survivorship, focused on prevention, or exploring integrative approaches alongside conventional care — Rivvn meets you where you are.
We believe in evidence-based medicine as the foundation of cancer care. Your oncology team is your primary guide. Rivvn supports your conventional treatment with deep context, trusted research, and personalized intelligence.
We also believe in the full scope of what helps cancer patients thrive — nutrition, movement, mind-body practices, integrative therapies, and community. Where evidence exists for these approaches, we present it honestly. Where evidence is limited, we say so.
We don't tell you what path to take. We give you the intelligence to make the decisions that are right for you, in partnership with your care team.
