Who we are

Founders’ Story
For us, cancer isn’t abstract — it’s personal.
‍
Each of us has faced it in our own family — the fear, the fight, and the fragile hope.
We’ve lived it.

OncoHelper AI was born from that simple truth: when you’ve seen what cancer can take, you never forget what it means to fight back.

We are fighters. We bring that same strength to our mission: helping others fight smarter, earlier, and never alone.
‍
Together, we’re building what we once needed ourselves. Because no one should have to face this fight without support, or without hope.

Team Assembly
The right team drives success.
‍
We assemble teams from aims to roles. Each project aim becomes clear roles and responsibilities — Principal Investigator, Co-PI, Biostatistician, ML Scientist, Clinical Lead, Site Operations, Quality Control.
We assess skills, track record, and communication style through structured interviews and references.
Try before commit: a short pilot sprint with defined goals and peer review.
Govern for speed and safety — decision rights, escalation paths, and quality checks are fixed early.

Outcome: small, compatible teams that hit milestones fast and turn ideas into publishable evidence and clinical practice.
With your support, we will make a difference

Join us in our fight with cancer!
