Yuimedi, a medical data utilization company, raises 450 million yen and becomes the third Japanese team to be selected for the Alchemist Accelerator.
Sep 30 2023 – Yuimedi, the developer of a medical data utilization platform, announces that it has raised a total of 450 million yen through a pre-series A private placement of new shares. Chiba Dojo Fund, Nissay Capital, D4V, Coral Capital, DG Daiwa Ventures, and Incubate Fund (an existing shareholder) are the underwriters for this round.
In addition, we have been selected for an acceleration program offered by Alchemist Accelerator, one of the leading accelerators in Silicon Valley. We are the third Japanese team to be selected for this program and will be leveraging this opportunity to enter the U.S. market.

In recent years, there has been a growing demand from society to better utilize medical data. It is said that medical data obtained through daily medical procedures called Real World Data (RWD), such as electronic medical records, has the potential to provide value to patients through the provision of more appropriate treatment and drug development. Increasing the utilization of RWD is also becoming a priority for national and local governments as it can contribute to the reduction of medical costs.
On the other hand, as the spread of the coronavirus has shown, Japan is lagging behind the world in regards to RWD utilization. One of the blockers for better RWD utilization is that RWD such as electronic medical records are not well-formatted and in the form of “structured data,” and therefore is not designed for data analysis. Currently, the “data cleansing” process to clean up this unstructured data is performed manually, taking an enormous amount of man-hours.
To solve this challenge, Yuimedi has developed “Yuicleaner,” a no-code, easy-to-use software for data cleansing that does not require programming knowledge. Yuimedi believes that the creation of cleansed RWD will lead to a more active exchange of RWD between data holders, such as hospitals, and data utilizers, such a pharmaceutical companies, ultimately providing value to patients.
In addition to the development and provision of “Yuicleaner,” Yuimedi provides support to hospitals for the construction of medical databases and consultation to pharmaceutical companies on the use of medical data, aiming to build a platform that facilitates the exchange of RWD between data owners and users. To achieve this goal, the company plans to conduct four joint research projects with national hospitals and other organizations, and has about 10 business partners.
We believe that there are some areas in the U.S. market related to the utilization of medical data that are more mature than in the Japan market. Therefore, with the goal of reimporting business in the future and with our inclusion into the Alchemist Accelerator in 2023, we have decided to develop our U.S. and domestic business at the same time. The funds raised will be used for platform development in Japan and to build a foundation for U.S. expansion.

While the healthcare industry has made progress on the digitalization of medical records, the databases are still disparate and lack interoperability. Many of the potential benefits of leveraging this data cannot be realized without proper cleansing to make it useful. Yuimedi is leading the way by bringing together a strong team at the intersection of healthcare and engineering to build solutions to overcome these complex challenges. We’re excited to play a small part in this ambitious and important endeavor.

【Comments from CEO and Representative Director, Eimiri Grimes】
When I was a graduate student, I was also engaged in epidemiological research dealing with medical data. One of the issues I felt at the time was that if the necessary data could be easily obtained from the real world in a clean format, research activities could be conducted more quickly. Yuimedi was launched in the hope of overcoming these challenges and creating a world in which medical research using data can flourish.
This world needs to be created together with all stakeholders, both owners and users of medical data. Through this fund raising, Yuimedi will unite more stakeholders and strive to realize its mission of “delivering necessary medical care to necessary patients through data”.
