Deallus is a global life sciences consultancy with a 20-year heritage in competitive intelligence. Our name is a Celtic word meaning 'intelligent', 'understanding', and 'wise' — qualities that underpin every engagement we deliver. We partner with the world's leading pharma companies, as well as emerging biopharma and med-tech, helping our clients navigate complex, dynamic, and highly competitive markets. Operating across six offices on four continents, with over 25 languages spoken, we function as one global team — an extension of our clients' internal capabilities. Acquired by GlobalData in 2025, we continue to lead the industry in shaping and refining life sciences strategy.

We are a diverse, passionate team of commercial scientists who bring a peer-to-peer partnership model to every client engagement. Our shared understanding of how science intersects with commercial market realities allows us to generate bespoke solutions to unique organisational challenges. We nurture and retain top talent by cultivating an inclusive culture where expertise, curiosity, and collaboration thrive — across London, Tokyo, New York, Los Angeles, Shanghai, and Gurugram.

We deliver true strategic intelligence across the entire product life cycle. Our capabilities span competitive intelligence, brand and therapeutic area strategy, product launch, pricing and reimbursement, scenario planning, war gaming, benchmarking, and C.I. best practice advisory. We apply bespoke, robust methodologies — including primary research, market landscaping, workshops, and forecasting — to unearth actionable insights and provide evidence-based recommendations that help clients outmanoeuvre the competition.

Our purpose is to prepare our clients for the future by delivering forward-thinking assurance in an uncertain and highly competitive world. We lead the industry in shaping and refining strategies for those striving to advance healthcare and improve patients' lives — combining deep therapeutic area expertise with global reach and rigorous analytical thinking to give our clients the confidence to make the right strategic decisions.

Our vision, mission, and values were co-created by our entire global team — a reflection of who we are and who we aspire to be. We live and breathe these values daily, making time to recognise our colleagues when they exemplify the behaviours that make Deallus special. Our leaders set the example: working hard together, sharing passion for what we do, and enjoying each other's company along the way.

Clients choose Deallus for our class-leading reputation and heritage, extensive therapy area expertise across neuroscience, oncology, rare diseases, and vaccines, and our global reach with local knowledge. Our proven systematic approach to information gathering, the high quality of our analysis, and the depth of knowledge and clarity we generate are consistently cited by clients as decisive differentiators. We become an extension of your team — not a one-off supplier.

Deallus is committed to taking our corporate citizenship responsibilities seriously. Our goal is to exemplify sustainable business practices and create an environment in which our people feel empowered to make the world a better place. From offsetting our carbon footprint and partnering with sustainably responsible office suppliers to enabling our team to perform charitable work for causes close to their hearts — we strive to exist in the corporate world with pride about our impact on the environment and in our communities.

Our teams around the world take action in their local communities. Our Tokyo team harvested sweet potatoes for local elementary school lunches at a privately-owned farm. Our London team spent an afternoon with London Play Design, restoring a children's adventure playground in a less affluent area of the city. Our Los Angeles team conducted a beach clean-up at Santa Monica Beach, collecting batteries, face masks, and non-biodegradable plastics. These are not one-off initiatives — they reflect a genuine culture of care that extends beyond the office.
