Reference Medicine is your hassle-free source for oncology specimens - built for scientists, by scientists. Diagnostic companies and researchers in oncology are continually pushing the envelope and seeking new diagnostic tests, therapeutic treatments, and novel options to improve patients’ lives and health. At Reference Medicine, we think this same ambitious attitude of innovation and continual improvement should be applied to specimen procurement, which is why we’re doing things differently. We take a fresh approach to fully transparent procurement, delivering high quality, affordable samples in a timely manner, so you can focus on the science. We innovate so you can innovate.

We believe people should not care about privacy. Not because it doesnt matter, but because it shouldnt be an issue! From data breaches and surveillance of cloud applications, to blockchain smart contracts where everything is public, doing things privately online is becoming increasingly complicated. The only way to solve this is to make everything encrypted end-to-end, regardless of where the application is running. And the only way this can happen is if homomorphic encryption becomes mainstream. We are a remote-friendly company with headquarters in the centre of Paris.

Primary Ocean develops macro-algae (kelp/seaweed) cultivation and processing systems to help heal our oceans, soils, and atmosphere. Seaweed is one of the oldest, most renewable, and regenerative biomass resources on Earth. When cultivated, it can draw down Carbon up to 14% faster than tropical rainforests, mitigate ocean acidification, and anchor ecosystems through primary production and habitat creation. When processed, seaweed products can offset major petrochemical pollutants including fossil fuels, plastics, and agrochemicals. Primary Ocean’s first commercial product is an incredibly effective crop input called a liquid seaweed extract. Primary's agricultural products allow the farmer to reduce water, fertilizer and pesticide requirements, regenerate eroded soils and greatly improve farmers' crop yields, quality, and profits in both conventional and organic farming systems.
