Marble Health, a trailblazing mental health startup dedicated to empowering teens and families, has raised $15.5 million in Series A funding to expand access to evidence-based, tech-enabled mental healthcare. The round was led by Costanoa Ventures, with participation from Town Hall Ventures and Khosla Ventures, signaling strong investor confidence in Marble’s mission to reshape how young people experience care in the digital age.

Founded by Jake Sussman and Dan Ross, Marble Health is addressing one of the most urgent crises of our time  -  the mental health epidemic among youth. Their vision is both ambitious and deeply needed: to create an ecosystem where adolescents can access quality therapy, personalized treatment, and community support without stigma or delay.

Transforming Teen Mental Health Care

The youth mental health crisis is accelerating at an alarming pace. According to the CDC (2024), nearly 42% of teenagers report experiencing persistent sadness or hopelessness, and suicide remains the second leading cause of death among young people aged 10–24. Despite this, over 60% of teens with mental health conditions receive no treatment.

Marble Health exists to close that gap. Its platform combines clinically proven therapies, digital monitoring tools, and personalized care plans to connect teens with therapists, psychiatrists, and peer communities who understand their needs.

“Young people today are struggling like never before,” said Jake Sussman, CEO and Co-Founder of Marble Health. “We’re building a system that meets them where they are  -  online, accessible, and connected  -  but with the clinical rigor families deserve.”

Marble’s approach integrates human empathy with technological efficiency, enabling real-time tracking of progress, faster intervention when symptoms worsen, and seamless coordination between patients, parents, and clinicians.

A Platform Built for Modern Mental Healthcare

At its core, Marble Health’s platform is designed around accessibility, personalization, and privacy. Through a secure app interface, users can:

• Match with licensed therapists and psychiatrists based on need and preference.
  
• Access self-guided therapy modules based on cognitive-behavioral principles.
  
• Track mood, habits, and treatment progress via AI-assisted journaling.
  
• Receive peer support in moderated community spaces.
  

This hybrid model of digital convenience and human expertise ensures that care isn’t just available  -  it’s consistent, adaptive, and sustainable. For clinicians, Marble provides integrated data dashboards to monitor outcomes and tailor interventions, significantly improving the precision of care delivery.

By prioritizing the teen experience, Marble Health stands apart from traditional teletherapy platforms. It speaks the language of its users  -  one rooted in authenticity, relatability, and hope.

Solving the Right Pain Point

Marble Health’s success carries an essential insight for founders: don’t just build technology  -  solve the human problem first.

In mental healthcare, technology alone cannot replace empathy. What differentiates Marble is its deep understanding of both the clinical and emotional dimensions of youth mental health. The platform doesn’t chase automation for its own sake; instead, it uses AI and data as tools to enhance human connection, not replace it.

This balance of innovation and empathy has become a defining feature of successful healthtech ventures. As mental health solutions flood the market, founders who understand this intersection  -  between tech precision and human depth  -  are those most likely to create lasting impact.

Scaling Compassion with Data

What makes Marble especially compelling is its approach to evidence-based scale. Every session, engagement, and outcome feeds back into a learning system that continuously refines treatment recommendations.

Through data analytics and machine learning, Marble identifies patterns of early distress, enabling proactive interventions before crises occur. This shift  -  from reactive to preventive mental healthcare  -  could redefine how the industry approaches long-term well-being.

It’s a reminder that mental health innovation isn’t about more apps or screens; it’s about using data to restore agency, not anxiety.

The Growing Market for Digital Mental Health

The mental health tech market is one of the fastest-growing segments in healthcare. According to Grand View Research (2024), the global mental health app market is projected to reach $28 billion by 2030, growing at a CAGR of 17%.

Driving this surge are:

• Rising mental health awareness among younger demographics.
  
• Shortages of licensed clinicians, particularly for adolescent populations.
  
• Advancements in telehealth and AI-driven monitoring.
  

In the U.S. alone, teletherapy sessions have increased sixfold since 2019, and digital-first care models are becoming the new standard. Marble’s timing  -  focusing squarely on youth and family mental health  -  places it in one of the most impactful growth niches in modern healthcare.

What’s Next for Marble Health

With its $15.5 million Series A, Marble Health plans to:

• Expand its clinical network to reach more states and school systems.
  
• Enhance its AI capabilities for real-time triage and care coordination.
  
• Launch new programs for family therapy and adolescent psychiatry.
  
• Partner with healthcare systems and payers to improve access through insurance coverage.
  

“We’re building an infrastructure for lasting mental wellness  -  one that empowers teens and families to heal, grow, and thrive,” said Dan Ross, Co-Founder and COO of Marble Health.

By combining empathy, evidence, and innovation, Marble Health is poised to become a defining leader in digital youth mental health.

The Broader Implication: The Humanization of Digital Care

Marble Health represents a broader shift in the healthcare ecosystem  -  one where digital tools no longer depersonalize care, but personalize it at scale.

As mental health crises grow more complex, and as technology becomes more intertwined with human development, the startups that win won’t be those with the flashiest interfaces  -  but those that build trust, compassion, and measurable outcomes into every interaction.

Marble Health isn’t just changing how care is delivered. It’s rebuilding what care feels like for an entire generation.
