Strategic Finance for Life Science Tools & Diagnostics

O'Halloran Capital is a specialist angel-scale investor focused exclusively on early-stage life science tools, diagnostics, and enabling technologies. We partner with ambitious founders who are developing innovative solutions capable of transforming research, healthcare, and patient outcomes.
Our investment focus spans company formation, pre-seed, and seed-stage opportunities. We are particularly attracted to businesses operating at the intersection of biology, engineering, data science, and advanced diagnostics, where breakthrough innovation can create substantial commercial and societal impact.
We invest in exceptional founding teams pursuing opportunities with genuine venture-scale potential. While technology and intellectual property are important, we believe that great companies are ultimately built by talented, resilient, and coachable entrepreneurs with the vision and determination to execute.
As experienced founders and operators ourselves, we are comfortable investing at the earliest stages of a company's journey, often providing the first external capital into a business. Beyond funding, we work closely with founders to help refine strategy, build high-performing teams, navigate technical and regulatory challenges, secure commercial partnerships, and prepare for future institutional investment.
Our approach is long-term, hands-on, and founder-friendly. We seek to become trusted partners to entrepreneurs, helping them progress from an initial concept to a scalable business capable of attracting venture capital and delivering meaningful exits.

We typically look for:
We are particularly interested in opportunities within molecular diagnostics, in vitro diagnostics (IVD), genomics, synthetic biology, laboratory automation, AI-enabled healthcare technologies, life science tools, and platform technologies with broad applicability across multiple markets.
O'Halloran Capital is more than a source of capital. We have built, scaled, and exited companies in the life sciences sector. Having raised over £100 million in equity, grant, and strategic funding, we understand the challenges founders face from the earliest stages of company creation through to commercialisation and institutional investment.
We invest early, often before traditional venture capital firms become involved, and work closely with founders to help shape strategy, refine business models, build investor networks, and navigate the technical, regulatory, and commercial hurdles unique to life science tools and diagnostics companies.
Our goal is simple: to help exceptional founders build valuable businesses that deliver both strong financial returns and meaningful societal impact. We bring capital, experience, networks, and a long-term commitment to supporting innovation that improves healthcare and advances scientific discovery.
We'd love to hear about your ideas, regardless of how developed they are.
