Clue, the Berlin-based period and cycle tracking app, has announced a significant strategic investment from European growth equity firm Verdane, as it looks to accelerate its global growth and product development.
While the financial terms were not disclosed, Clue said the funding represents a substantial commitment from Verdane’s €2 billion growth fund and is the single largest investment the company has received to date. Following the transaction, Verdane will become Clue’s largest investor.
Founded as a digital health platform focused on menstrual and reproductive health, Clue reports more than 100 million downloads worldwide. The app is currently available in 23 languages and used across more than 190 countries. The investment comes after what the company described as an exceptionally strong 2025, which it said helped lay the groundwork for long-term profitability.
Clue said the new capital will be used to drive product innovation and the development of new features, expand its international footprint, and deepen partnerships within the healthcare sector. Additional areas of focus include clinical research, enhanced privacy and security measures, and advances in personalisation technology.
Rhiannon White, CEO at Clue, said the investment addresses a broader imbalance in the health and wellness market. “Women are the world’s largest health and wellness consumers, controlling the majority of household spending in every market, yet they remain strikingly underserved relative to their economic power,” she said. “This gap creates three systemic pain points: a profound lack of accessible female health knowledge that forces women to self-diagnose, a confusing marketplace filled with unproven products and little evidence-based guidance, and persistent barriers to accessing care. For businesses, this represents not just a social issue but a significant market failure and a compelling opportunity to build trusted, data driven solutions that meet the needs of the most influential spenders in global health and wellness.”
White added: “Partnering with Verdane enables us to accelerate the creation of this powerful ecosystem and tackle these issues for women. Verdane’s deep expertise in growing sustainable businesses, combined with their extensive operating experience in the health and wellness space means they bring unparalleled support to the opportunity in front of us.”
From the investor side, Verdane highlighted Clue’s market position and credibility. Christina Stoll, Principal at Verdane, said: “We are highly impressed by the Clue management team and the strong momentum the business is demonstrating. Clue has earned exceptional user trust by combining the highest data protection standards with rigorous, science-based insights in a category where credibility truly matters. Consumer demand and awareness for trusted women’s health solutions continues to accelerate, and Clue is uniquely positioned to lead this space.”
She added: “Clue’s women-led, mission-driven approach and focus on meaningful impact strongly align with what Verdane stands for.”
Verdane is a certified B Corporation and has raised more than €9 billion in capital since 2003. The firm operates from offices in Berlin, Copenhagen, London, Helsinki, Munich, Oslo and Stockholm.
