Rhia Ventures

Rhia Ventures’ mission is to create a vibrant US market for sexual, reproductive, and maternal health that produces equitable outcomes for all. 

This multi-billion dollar market has tremendous potential for public health impact, but it has been built on flawed systems that perpetuate unjust outcomes for women of color, low-income women, and others directly affected by systemic inequities. Our work is to transform this market. 

We know that transformation happens when partners with long experience in reproductive health and justice come together with market-facing actors to create deep, meaningful impact. By connecting activists, public health professionals, scientists, entrepreneurs, corporates, and investors, together we will build a more just marketplace.

Rhia is enabling this change through four complementary efforts:

We make direct investments in early- and growth-stage companies that are driving innovation, access, and equity in reproductive and maternal health, through our wholly owned venture fund, RH Capital Corporation.

We provide technical assistance and shared resources to these companies and others so that they can strengthen their work in health equity and spur change across the venture ecosystem.

We work through our Corporate Engagement and Blossom programs to change social norms, practices, and people that influence this market.

We produce a systems-change assessment of the market, identifying the key leverage points for addressing systemic racism and other inequities to inform Rhia’s programs and share with grant-makers, investors, and policy-makers seeking to “make this market work for justice,” to paraphrase Darren Walker of the Ford Foundation.

Our Vision for Success

Alongside our partners, our efforts will:

  • Catalyze investment in innovation that improves equity, access, and outcomes in reproductive and maternal health care
  • Transform systems in the reproductive and maternal health market, to redress systemic inequity and contributes to improving reproductive and maternal health outcomes for women of color, low-income women, and others directly affected by systemic inequities



  • Amplify the perspectives and work of stakeholders of color
  • Strengthen social norms, to support high-quality maternal and reproductive health care for all women and birthing people in the US


Our 501c3 and Fund focus on 3 complementary areas of work:
  • Direct investment in early and growth-stage companies
  • Market analysis, and support to our portfolio companies 
  • Field-building and corporate engagements
These pillars of our work across the c3 and the Fund enable us to:
  • Encourage investment in the areas of the market that need it most
  • Fund public goods and services that grow the market in equitable, profitable, and sustainable ways
  • Engage and illuminate stakeholders of color
  • Strengthen social norms to support quality maternal and reproductive health coverage and treatment of women in US workplaces
