Ladder Health, a Massachusetts-based virtual-first pediatric developmental care company, has raised $7M in seed funding led by Nina Capital. The company delivers speech, occupational, physical, and feeding therapy for children ages 0-6 through an AI-enabled, caregiver-activated model developed with Boston Children's Hospital. The capital will support expansion across North Carolina, Massachusetts, and Maryland plus continued investment in its AI platform and health system partnerships.
Waitlist Crisis Drives Investor Interest
The timing aligns with acute pressure on pediatric therapy access. Coral Care raised $13M Series A in February 2026. Expressable secured $26M Series B in 2024. Positive Development closed $51.5M Series C in August 2025. Ladder Health's approach trains parents as therapeutic partners between sessions, reducing referral-to-first-appointment time from the industry standard of six-plus months to an average of 10 days.
Severe Access Bottlenecks Quantified
One in four children under age 6 are at risk for developmental delay or disability. Families on Medicaid and in rural areas face the longest delays, with autism assessments averaging 6-12 months followed by additional 3-9 months for therapy. More than 27 million children in the U.S. are in the critical first 2,000 days of life. Traditional clinic and in-home models cannot scale fast enough amid provider shortages.
Caregiver-Activated Model Differentiates
Ladder Health operates virtually across speech, occupational, physical, and feeding therapy under one platform, unlike Expressable which focuses on speech only. It differs from Coral Care's in-home visits and Positive Development's autism-exclusive focus. The AI platform handles scheduling, messaging, and progress tracking while clinicians coach parents to extend therapy into daily home routines. Boston Children's Hospital co-developed the clinical model and holds an equity stake.
"What makes the AI-enabled model distinct is that it's caregiver-activated: our clinicians work directly with parents and caregivers, equipping them to support their child's progress at home between sessions, where the majority of developmental growth actually happens." — Mitch Mudra, CEO
Nina Capital Leads Mission-Focused Syndicate
Nine investors participated in the oversubscribed round, including Mairs & Power Venture Capital, South Dakota First Capital, Hatteras Venture Partners, and Create Health Ventures. Nina Capital's healthcare focus signals conviction in virtual models that expand capacity without new physical infrastructure. The company currently partners with more than 80 provider organizations and health systems and reports a Net Promoter Score of 92. Medicaid families represent 65% of its patient base.
Overlapping Markets in Tens of Billions
The U.S. speech therapy market stands at $5.72B growing at 8.2% CAGR. U.S. occupational and physical therapy services reached $65.36B in 2025. The online therapy services market is $12.73B growing at 14.8% CAGR. Structural drivers include post-COVID acceptance of telehealth, policy emphasis on early intervention, and health systems seeking scalable solutions to workforce shortages.
Expansion Timeline and Hiring Signals
Ladder Health plans to enter 1-2 additional states by year-end. It does not expect to raise again until the end of 2027. Recent activity includes hiring a Chief Operating Officer and searching for a Head of Marketing, alongside a white paper release detailing clinical outcomes.
