Winter Street Ventures (WSV) has a proven history of scaling transformative healthcare companies. Founded and relaunched as an independent fund by Chris Palmieri—a seasoned operator who has successfully guided multiple billion-dollar organizations through growth, turnarounds, and acquisitions—WSV is uniquely positioned at the intersection of healthcare delivery, technology, and public policy. Backed by a deep bench of partners and advisors with expertise spanning venture capital, federal health policy, and healthcare innovation, WSV is focused on identifying high-potential opportunities, engineering successful exits, and delivering top-quartile returns. With a differentiated focus on technology and AI-driven enablement, WSV combines operational know-how with strategic relationships across payors, providers, and health systems to capitalize on some of the most needed areas for healthcare innovation and disruption.
Investment Strategy
- Focus areas. Tech-enabled healthcare across three thematic buckets:
- ◦ Care Delivery — in-home care, value-based care enablement, care coordination, social care, specialty care
- ◦ Clinical AI — diagnostics, clinical decision support, predictive analytics for patient outcomes
- ◦ Operational AI — revenue cycle automation, prior authorization, workforce operations, process automation
- Stage. Series A focus (approximately 80%) with selective Seed investments (approximately 20%). Check sizes of $2M–$8M with capital reserved for follow-on rounds.
- Ownership. Target meaningful minority positions with board and governance rights. Pre-money valuation discipline at or below $30M — preserving multiple expansion at exit.
- Return objective. Top-quartile by Cambridge Associates and Preqin vintage benchmarks. Underwritten target: 4–5x at Series A and 7–10x at Seed.
Our Experience
- Track record. 10 healthcare investments generating a 5.2x gross multiple on invested capital, including a 4.7x unrealized return on an API-connected fintech-as-a-service platform for healthcare and a 2.1x realized return on a SaaS data management platform for risk adjustment.
- Proprietary sourcing. 10K+ companies in the WSV CRM, 100+ health system partners, 50+ payer organizations, and 150+ private equity, venture capital, and consulting relationships. 100% of investments come through WSV’s direct sourcing network.
- Value creation. Active portfolio engagement, board and governance support, commercialization guidance through WSV’s payer and provider relationships, and access to a deep talent and advisor network.
