We are a pre-seed femtech startup building pHera: an ultra-precise colorimetric vaginal pH test that can be read with a smartphone using computer vision and AI for accuracy and personalisation. The system would detect colorimetric images and predict with a high level of accuracy discrete pH values, delivering lab-quality diagnostic precision to women and doctors - anytime, anywhere!

• Build computer vision models and ensure reliability across diverse phones and lighting.
• Personalize results using Bayesian hierarchies and time-series methods to learn individual baselines and detect meaningful changes.
• Pair model outputs with concise, evidence-backed explanations using LLMs with retrieval and citation grounding.
• Establish evaluation, monitoring, and privacy-minded data workflows suitable for a regulated context.

• Based in Berlin is prefered but not required
• Eager to work in an early-stage, science-driven, female health startup
• Comfortable with ambiguity, self-directed, and proactive

pHera is closing the gender health gap!
Most existing vaginal pH test strips are analog, low-resolution, visually subjective, and
poorly suited for women’s health applications. Doctors need fast, reliable tools to
help with complicated diagnoses. Women deserve clarity, not guesswork when
managing their vaginal health from home. A high-resolution pH test can catch
imbalances early, making it easier to monitor issues like bacterial vaginosis,
recurring vaginal infections, sexually transmitted infections, ovulation, PCOS, and
menopause. By building pHera, you would be building a tool that would advance women's health.
