We focus solely on what you need here and now, to help you move to the next stage in your development strategy. We offer stage appropriate development for each programme, focusing on problem solving to help our clients reduce the risk of failure during the later development stages and maximising the returns from potential in-licensing partners.

Solitek was launched in 2021 and is located in the Parc Cientific of Barcelona, a major scientific hub in the heart of Barcelona, Spain. We are a small, agile team, we promote collaboration over competition, and we believe in the synergy of two teams working together towards a common goal. Our studies carry the inherent flexibility associated to early development programmes. We offer the best value for money available anywhere in the world.

The founders have a combined experience of over 50 years in the pharmaceutical industry, working in the discovery, early development and manufacturing phases of small molecule active ingredients. This includes a combined experience of over 40 years in the world of solid state research and crystallization development, leading some of the largest teams in Europe dedicated to the provision of solid state services, and being involved in over a thousand development programs, many of which have now reached market status.
