SpringTide Ventures Research
Investment Thesis
SpringTide Ventures is a specialized health-tech venture capital firm founded in 2018 by repeat healthcare founders who have previously started, scaled, and exited healthcare companies. The firm is built on the conviction that the greatest health-tech innovations come from founders with deep healthcare experience and entrepreneurial track records. SpringTide leads early-stage financings for tomorrow's greatest healthcare companies, with an embedded Chief Medical Officer and clinical operators who provide hands-on support to founders tackling underserved patient populations and broken healthcare delivery models.
The firm operates with a unique infrastructure: 22 venture partners providing direct access to policymakers and system leaders, alongside a 114-person investor network. This structure allows SpringTide to do more than provide capital—they offer operational expertise, regulatory guidance, and access to high-value relationships across healthcare delivery, payers, and policy.
Stage Focus
SpringTide Ventures invests primarily in Pre-Seed, Seed, and Series A stages:
- Pre-Seed: Early-stage validation with working prototypes
- Seed: Companies with initial traction and product-market fit signals
- Series A: Selected follow-ons for companies with strong momentum
The firm is not a late-stage investor. Their sweet spot is identifying exceptional teams early and providing deep operational support through critical inflection points.
Check Size
Typical investment range: $500K - $5M
- Pre-Seed: $500K - $1.5M
- Seed: $1M - $3M
- Series A: $2M - $5M (selective)
Based on their portfolio and fund size, SpringTide typically targets 10-15% ownership stakes in their investments, giving them board influence while leaving significant upside for founders and follow-on investors.
Lead Tendency
SpringTide leads the majority of their investments. This is reflected across their portfolio:
- Leads seed rounds with clean terms
- Co-leads larger rounds with experienced co-investors
- Occasionally participates in Series A follow-ons for exceptional companies
Their track record shows strong conviction in the companies they back, with most investments seeing them in the lead or co-lead position.

Decision Process
Structure: Partnership-based with collaborative investment committee
SpringTide's decision process emphasizes team evaluation above all else. Partners note that they evaluate opportunities on three main factors: the team, the market, and the idea—with team being "by far the most important."
Process characteristics:
- Founder-centric (built by repeat health-tech founders)
- Operational deep-dives before commitment
- Clinical validation integrated into diligence
- Board-level involvement post-investment
- Strong follow-on support and strategic guidance
Founder Preferences
SpringTide strongly favors:
-
Repeat Healthcare Founders - Founders with prior healthcare company experience, exits, and operational scars
-
Clinical Expertise - Founding teams including physicians, clinicians, or scientists who deeply understand the problems they're solving
-
Problem Validation - Founders solving real, measurable healthcare delivery problems with direct stakeholder engagement
-
Operational Sophistication - Teams that understand regulatory, reimbursement, and healthcare delivery complexity from day one
-
Patient-Centric Focus - Founders obsessed with improving outcomes for underserved or overlooked patient populations
Anti-thesis: Consumer apps without health outcomes, speculative biotech without experienced teams, and founders without healthcare domain expertise.
Geographic Focus
Primary regions:
- Boston Metro (Cambridge headquarters) - Deep healthcare ecosystem access
- San Francisco (secondary office) - Tech talent and AI/ML infrastructure expertise
- Salt Lake City (secondary office) - Emerging health-tech hub with strong founders
- US-focused with selective international interest in health-tech innovation
The firm has expanded to three major locations to be close to both healthcare innovation hubs and tech talent centers.
Fund Structure & Deployment
Fund III: $150M (2025 vintage, actively deploying) Fund II: $65M (2024, completed deployment) Total AUM: Approximately $150M-$200M across active funds
The firm is selective about fund size, keeping funds at $65-150M to maintain founder-focused attention and operational support quality.
Notable Program: Wave Summit & Wave Labs
SpringTide operates Wave (wave.springtide.com), a proprietary platform bringing together healthcare innovators, entrepreneurs, policymakers, and system leaders. Wave Summit is an annual gathering of 400+ health-tech founders and leaders; Wave Labs provides content platform and collaborative infrastructure. This is a significant value-add: networking, insights, and policy/payer relationship building for portfolio companies.
