Updated: Oct 17
Medical device startups have 8 primary funding sources: government grants ($305K-$3M, non-dilutive), angel investors ($50K-$2M, 10-25% equity), venture capital ($1M-$100M+, 15-30% equity per round), crowdfunding ($50K-$1M, variable terms), accelerators ($25K-$250K + mentorship), corporate partnerships, revenue-based financing, and bootstrapping. The smart play is sequencing: validate with grants, bridge with angels, then scale with venture—layering in partnerships or revenue-based financing when it fits your model.
This guide shows the main sources, realistic check sizes, and how to time each step for faster runway.
The Medical Device Funding Reality: 2025 Market Conditions
The healthcare funding landscape has fundamentally shifted. According to Rock Health, U.S. digital-health startups raised $10.3 B in H1 2022, down 30 % from $14.7 B in H1 2021, signalling a decisive post-pandemic reset.
The Good News: The health sector has held up better than other major industries. While SaaS funding decreased by 70.1% and fintech by 78.5%, the health sector shrank by only 44.1% since Q1 2022. The health sector's share of all venture capital invested has risen from 21% in 2018 to 32% in 2024.
What This Means for Founders: Capital is still flowing—but only to evidence-rich, milestone-ready medtechs. Investors are choosy, favouring startups that blend non-dilutive grants with staged equity to de-risk FDA and market-access milestones.
