Through the decades, clinical research has suffered from a notorious blind spot: its failure to fully account for female biology. Historically, women, particularly those of reproductive age, were marginalized in clinical trials for reasons ranging from supposed hormonal complexities to concerns over fetal health. This has left a critical gap in data that impacts women’s healthcare outcomes to this day. Enter TrialMe, a Swedish startup founded by medicinal chemist Hanna Kalesse, aiming to revolutionize how women are represented in clinical research.

TrialMe’s solution is both simple and disruptive, it provides women with an accessible, transparent gateway to participate in clinical trials, ensuring their data significantly contributes to the medical research ecosystem. As an entrepreneur myself, deeply embedded in Europe’s startup and tech scene, I believe this is more than just a technological fix; it’s about rewriting decades of ingrained inequality in healthcare with focused, data-driven solutions. Let’s explore how TrialMe is solving this problem while reshaping perspectives on gender equity in clinical testing.

Why Have Women Been Left Out of Clinical Trials?

The scientific bias that excludes women from clinical testing has historical roots. Before 1993, when the NIH first mandated gender inclusion in government-funded U.S. trials, drug testing in the Western world predominantly revolved around male subjects. Europe legislatively addressed this much later, in 2022, with amendments to the EU Clinical Trials Regulation. Unfortunately, these changes have been slow to filter through, leaving a legacy of incomplete, male-biased medical research.

  • Drug dosages are frequently calibrated based on male physiology, leading to higher rates of adverse drug reactions in women.
  • Many life-altering conditions that disproportionately affect females, such as autoimmune diseases and chronic pain, remain under-researched due to this bias.
  • Women of childbearing age are often excluded entirely due to concerns about unforeseen effects on pregnancy.

Such exclusions perpetuate the notion that male biology is the default, a harmful myth that TrialMe seeks to debunk by not only inviting women into the clinical trial space but making their participation meaningful.

What Is TrialMe’s Unique Approach?

Rather than taking a generalized approach to trial recruitment, TrialMe focuses on addressing the visibility gaps in women-centered data. At its core is a mobile app crafted to make trial participation intuitive and bias-free. Here’s how it works:

  • Smart Matching: Using pre-set filters and questionnaires, the app matches users with trials that align with their health profiles, conditions, and symptoms.
  • Robust Transparency: Women see exactly how their data will contribute to research outcomes, fostering trust and accountability.
  • Incentivization: Trial participants earn rewards, like therapy discounts or wellness products, ensuring engagement while offsetting any challenges like time or logistical constraints.
  • Education: Through integrated tutorials and a community platform, TrialMe empowers users to understand how data is analyzed and why their biology matters.

As an advocate for useable tech, I see TrialMe as an exemplar of how to eliminate entry barriers through thoughtful design. Beyond ensuring representation, these elements build much-needed trust in a system that has historically sidelined certain demographics.

Why Data Representation for Women Matters

Why should entrepreneurs and the broader public care about female representation in clinical trials? The answer lies in the real-world consequences that ripple far beyond healthcare into productivity, quality of life, and broader socio-economic factors. Consider the data:

  • Women are nearly twice as likely as men to experience adverse drug reactions due to poorly calibrated dosages and side-effects.
  • Heart attacks present differently in women than in men, leading to frequent underdiagnosis or misdiagnosis.
  • Conditions like endometriosis and PCOS remain underexplored, affecting millions of women globally.

The absence of women’s data isn’t just a moral failure, it’s a financial and healthcare liability, reminiscent of the kind of blind spot that technologists and business founders like me are emboldened to address. Clear, inclusive data unlocks actionable insights for pharmaceutical companies, healthcare workers, and patients alike.

How Does TrialMe Build Trust?

Hanna Kalesse has flipped the script on the traditionally opaque world of clinical trials. Through her platform, she models the change she wants to see. By participating in clinical trials herself and sharing her journey transparently, she demonstrates authenticity and commitment to the cause. This simple leadership approach is already paving the way for wider adoption and trust-building among women.

The platform also incorporates a gamified rewards system. By acknowledging women’s contributions to science and incentivizing their time and effort, TrialMe taps into intrinsic and extrinsic motivators, a classic example of how gamification can work wonders beyond traditional tech education or productivity tools.

How Can Startups Play a Role in Addressing Systemic Bias?

Startups thrive by finding and fixing blind spots. It’s what set companies like TrialMe apart: leveraging technology and focusing on long-ignored or misunderstood problems to create scalable impact. This journey shows that tech isn’t just about efficiency or productivity, it can redefine norms by addressing underrepresented demographic needs.

  • Broaden your founding team to include diverse perspectives.
  • Design solutions that address underserved markets, whether it’s women, minorities, or otherwise overlooked groups.
  • Ensure accountability by building transparency and equal representation into your offerings.
  • Embed empathy and lived experience into product development; it’s not just smart, it’s good business.

If TrialMe teaches us anything, it’s that meaningful progress often starts with examining where we’ve failed in the past, and leaning into uncomfortable truths. For today’s entrepreneurs, the lesson is clear: inclusivity isn’t optional anymore; it’s central to both success and relevance.
