HelixScreen : Advancing Personalized Breast Cancer Care

What happens when a healthcare startup meets professionals from across the healthcare ecosystem? For Yueyun and Céline, co-founders of HelixScreen, the H4 experience was an opportunity to challenge assumptions, explore new perspectives, and refine their project through direct exchanges with experts in the field.

Can you introduce yourself in a few words: who are you and what does your startup do?

We are Yueyun and Céline, co-founders of HelixScreen.

Our startup is working to transform breast cancer care by enabling oncologists to identify the most effective treatment for each individual patient, moving away from trial-and-error approaches and toward true precision medicine.

What convinced you to join H4 and meet with healthcare professionals in the field?

We had heard very positive feedback from other startups about H4, both about their expertise and the quality of their network. What convinced us was the prospect of being introduced to the right people at the right stage: professionals who could genuinely challenge and enrich our thinking, not just listen to our pitch.

How did the hands-on experience go? Was there a particular meeting or moment that stood out for you?

The experience was remarkably rich. We had the opportunity to meet a diverse range of healthcare professionals, including a health economics expert, an oncologist, and a legal specialist, each bringing a distinct perspective that helped us both validate our assumptions and sharpen our project. Every conversation opened new angles we hadn’t fully considered before.

How did this direct contact with healthcare professionals influence or shape your project?

These exchanges were genuinely formative.

The health economics expert helped us quantify the concrete value our solution could bring, both to the healthcare system and to patients, which was critical for building a compelling case.

The oncologist gave us a much clearer picture of the patient journey and how care is structured in practice, helping us identify exactly where and how our startup could integrate into existing clinical workflows.

Finally, the legal expert provided valuable guidance on the regulatory and legal specificities that apply to our startup, an often overlooked but essential dimension at this stage of development.

And now, what are the next steps for your startup following the H4 experience?

We are focused on deepening our relationships with clinicians in the region to continue testing our solution in real-world settings. The connections made through H4 have given us a strong foundation, and our priority now is to translate that momentum into concrete validation milestones.

What message would you share with a startup considering going through H4?

We would wholeheartedly recommend it to any startup operating in the healthcare space. H4 offers something rare: direct, meaningful access to experienced professionals who engage with your project seriously. If you are looking to stress-test your assumptions and accelerate your learning in an immersive, human-centered way, H4 is the right place to do it.

Conclusion

Through H4, HelixScreen was able to engage directly with healthcare experts and gain valuable insights to support its development. The experience helped the team refine its thinking and identify key priorities for the next stage of the project.
