For all who approaches to health technology innovation

Premo Partners, Inc.


We encounter cases in which people raise seeds of new technology, and when they try to launch a product, they face problems such as not knowing how to do business, what they should start with, how they should build a strategy, and so on, and they take a long time to release these products, do not manage to do so at all, or, even though their products possess fantastic technology, their traits are not conveyed well and do not penetrate the market.

We would like to contribute to improve patients' QOL and save the lives of many.

At Premo Partners, together with everyone who wants to develop medical device and healthcare equipment, as well as everyone who wants to nurture current products into more valuable ones, we would like to constantly exercise a sense of ownership and focus on “Implement” as experts with practical experience in the field of medical device.

1. Hands-on service

For Startups
There are many corporations that end up putting off their marketing, sales, and regulatory affairs strategies because they can only afford the cost of developing the product specifications at the time of establishment. Developing products without creating a picture of what happens after the product is released into the market creates a large risk of its specs and conditions for approval not fitting the market and should be avoided at all costs. We create a picture of what happens after the product is released into the market together with you starting from the time of establishment and help you obtain regulatory approval while focusing on the market and product value after it goes on the market. We will undertake all other tasks for startups that currently on have seeds of technology.

2. Consulting service
