About Us

Crystallise Ltd was established in 2012. Our experience of clinical medicine, health informatics, programming and consultancy in healthcare, pharmaceutical, finance and other public sectors gave us a unique perspective on the benefits that arise from applying the learnings and approaches of one discipline to the problems faced by another industry.

The aim of Crystallise is to provide an innovative approach to processing information, using software tools to automate processes that are slower and less accurate when done by humans. Our approach provides clients with greater transparency and scope than they could find for the same budget elsewhere. We work with a network of experts and organisations that help us support clients efficiently and effectively, and are proud of our flexible and ingenious way of solving their problems.

Our medical and pharmaceutical experience

The Crystallise team has more than 50 years’ combined experience in providing services for healthcare and pharmaceutical clients.

Qualified doctors provide medical insight into mortality trends and their drivers. Clinical understanding means new medical developments are rapidly evaluated in the context of current practice and unmet needs.

Staff experienced in systematic reviews and evidence synthesis for pharmaceutical and health technology assessment clients ensure reports are based on systematic evaluation of the evidence.

Staff skilled in writing for a non-medical audience mean the evidence is synthesised into easily understood reports.

Pragmatic and systematic evidence synthesis skills mean bespoke reports can be adapted to your requirements, deadlines and budget.

The Crystallise team has more than 30 years’ combined experience in modelling data for healthcare, pharmaceutical and financial clients.

Data identification and cleansing skills and systematic review expertise ensure reliable and unbiased model inputs.

Smoothing and statistical expertise means data can be presented at different levels of granularity without losing validity or confusing outputs with unnecessary “noise”.

Staff with combined medical, financial and modelling skills mean model outputs make sense for clinicians, actuaries, financial advisors and healthcare payers or providers.

Mortality models allow you flexibility in choosing outputs, including central mortality, curves of death, life expectancy and years of life lost – overall and by cause of death.

The Crystallise team has more than 45 years’ combined experience in computer programming and software development for healthcare and financial clients.

Experienced programmers translate mortality models into easy-to-use software.

Medical input into graphic design provides clear representation of complex medical concepts.

The Crystallise team has more than 10 years of collective experience on interpreting mortality data for financial clients.

Staff with medical expertise rapidly identify significant medical advances that will affect mortality improvement.

JB Medical Ltd (Health Economics and Disease Modelling Consultancy)


JB Medical is a UK-based consultancy that uses the tools of health economics, disease modelling and evidence-based medicine to effectively communicate the roles and benefits of pharmaceuticals and medical devices within a cost-constrained health care environment.

The tension resulting from ever-increasing demands upon healthcare systems to provide access to innovative medicines with finite or diminishing resources has established a mandate for value-based decision making. With strict limitations being placed on manufacturers at both a national and local level, it has never been more important to be able to demonstrate the cost-effectiveness of new treatments. Appropriate research and health economic analysis must be clearly communicated to key purchasers to ensure identification of resources to drive change in clinical practice and so achieve marketing success. JB Medical has the experience and expertise to generate appropriate tools to maximise your success, together with effective communication of the results. Whether your objective is to secure Health Technology Appraisal approval for a new product, to maintain share in a mature market or to survive the transition to a generic environment, we can work with you to identify and deliver optimum marketing strategies.
