We are a Team of Award-Winning Scientists Creating a World with Healthier Microbiomes

Our platform is the result of our team’s combined expertise in genetics, epigenetics, and microbiome research.

We utilise deep molecular analysis and next-generation sequencing (NGS) technology to understand the impact of product usage on an individual’s microbiome.Through our efforts, we hope to revolutionise the way in which the industry develops and tests its products to deliver optimal results to those utilising them.

Our Mission

Sequential is the industry leader in clinical microbiome research and testing offering a comprehensive end-to-end platform designed to bring science-backed solutions to the personal care and pharmaceutical industry. Our mission is to understand the impact of the microbiome on the host (humans) and how the host impacts the microbiome in order to characterise human health fully.

We offer an extensive platform to conduct research on personal care products through microbiome testing, and biophysical assessments, and offer full recruitment services for studies. We are keen to publish our findings with our partners to increase the literature within this space. At present our database of over 20,000 human microbiome samples is one of the most sophisticated within the industry and is growing rapidly.
