Oxford Semantic Technologies develop RDFox, the first market-ready high-performance knowledge graph designed from ground up with semantic reasoning in mind. Oxford Semantic Technologies was founded in 2017 as a spin-out of the University of Oxford with a mission to bring cutting-edge research in semantic web technologies to industry. The team started working on RDFox in 2011 at the Computer Science Department of the University of Oxford with the conviction that flexible and high-performance reasoning was a possibility for data extensive applications without jeopardising the correctness of the results. Patented modern computing techniques underpin RDFox’s ability to deliver responses to complex queries on the fly. This has unlocked a new wave of enterprise applications for prestigious partners.

We have developed the only digital method of birth control cleared by regulators both in the US and in Europe. Effective, natural, and backed by clinical research - Natural Cycles has been cleared by the US FDA and CE marked in Europe. Today we have a growing user base, who are happy to have found a method of birth control that is right for them and that allows them to get to know their bodies and cycles. No matter what your choice is, we believe that every woman should know that understanding how your cycle works matters. Natural Cycles was created when our founders, Elina and Raoul, were in search of an effective method of natural birth control. Their journey took them from physics straight into health tech for women. The couple were unsatisfied with what they found, so they decided to apply their experience and knowledge in advanced mathematics and data analysis to develop a solution to meet their needs. This turned out to be an algorithm that detects and predicts ovulation and fertility. In the early days, they used the algorithm for their own purposes but quickly realized that there was a vast unmet need for this type of method. They decided to develop a mobile app so women from all over the world could easily access and use Natural Cycles. Our company has been up and running since 2013 and has been rapidly growing since our CE certification in February 2017. At Natural Cycles we are always looking for passionate talents to help us strive for change in such a complex, scientific, and controversial field. We have womens best interest at heart and work hard every single day to ensure that we provide the best possible solution. That’s why each and every team member is passionate about what we do. Gathered from all corners of the world we are a tight-knit international team located right in the center of beautiful Stockholm.

ElFys, Inc. was founded in fall 2017 to commercialize induced junction black silicon photodiode technology invented by a group of university researchers. We manufacture highly sensitive photodiodes with external quantum efficiency (EQE) greater than 96% over a broad range of wavelengths (250 to 950 nm). The superior sensitivity is achieved with our patented technology utilizing induced junction and black silicon. This combination eliminates practically all electrical and optical losses resulting into nearly ideal photodiode response. We have individual photodiodes available with standard sizes e.g. 5x5 mm2 and 10 x 10 mm2. Upon request, we can also produce custom sizes and shapes as well as arrays and matrices of photodiodes, enabling a drop in replacement of your current photodiode.
