What we do
RA Capital’s Structured Capital team invests across healthcare verticals including pharmaceuticals, medical devices and medical products, diagnostics, pharma services, healthcare services and HCIT. Our capital supports acquisitions, geographic expansions, launches, and R&D when equity isn’t the preferred option.
Why it matters
The right capital structure can extend runway, reduce dilution, and preserve strategic flexibility while aligning investors and operators around sustainable growth. RA Capital focuses on durable businesses where flexible capital can accelerate outcomes without forcing tradeoffs.
Our advantage
RA Capital is one of the most active investors in the healthcare and life science sectors. We have deep domain expertise built over two decades, allowing us to identify and support best-in-class, innovative companies looking for capital to drive growth.
TechAtlas insights, Raven's company-building infrastructure, and 20+ years of RA Capital relationships add value before, during, and after close.
We've evaluated more than 9,000 healthcare companies since 2020.1 Our team of 75+ MDs and PhDs means we understand the company, unmet needs, and markets, not just the financials.
We're instrument-agnostic: loans, convertibles, synthetic royalties, structured preferreds, and equity—whatever best fits the opportunity and the company.
A majority of our deals come directly from companies—not investment banks. Our network of 200+ portfolio companies and 100+ board seats creates access no one else has.2
Who we work with
We focus on healthcare and life sciences companies generating $15M — $500M in revenue — over 10,000 businesses across pharma, biotech, MedTech, diagnostics, pharma services, healthcare services, and HCIT — that are too innovative for bank debt, and too growth-focused to dilute with equity.

Think of Structured Capital investments as credit-oriented investments in innovative, revenue-generating companies.
RA Capital Structured Capital team pursues a distinct strategy with its own investment criteria and dedicated resources. However, their strategy benefits from RA Capital’s:
Where RA Capital already holds equity in a company, our Structured Capital team may also invest if the company meets our criteria. At times, we may offer a combined structured and equity solution when that best supports the company’s objectives.
This makes RA Capital a comprehensive multi-stage healthcare investor – we can support companies from inception through commercialization with the most appropriate form of capital at each stage.
RA Capital’s Structured Capital leverages the deep scientific, clinical, and commercial expertise of RA Capital, as well as our long-standing relationships across the healthcare ecosystem. This allows us to:
Unlike pure credit funds that view healthcare as just another sector, we understand the science, the regulatory pathways, the competitive dynamics, and the value drivers. This expertise translates into smarter deal structuring and more constructive partnerships.
Yes. We invest across every sector of healthcare and life sciences, including:
Our broad sector coverage and deep domain expertise allow us to evaluate opportunities across the entire healthcare value chain.
Our typical investment size ranges from $25 – $250 million, with the ability to go larger or smaller in certain situations depending on the opportunity and the company’s needs.
Yes. We invest in both public and private companies across healthcare and life sciences. The key criteria is that companies are commercial-stage (revenue-generating) and the capital will be used to drive growth.
Board rights are considered on a case-by-case basis and reserved for situations where we believe we can add meaningful value. Board participation tends to be more relevant when we have equity or equity-like exposure.
For pure credit investments, board seats are less common. For hybrid structures with equity components, board participation may make more sense.
