OPTiM, an AI and IoT software company listed on the Prime Market of the Tokyo Stock Exchange, has acquired shares in MediTech, a Tokyo company that makes a smartphone app for doctors to share medical images, and made it a subsidiary. OPTiM announced the deal in a press release on PR TIMES on November 2, 2026, and said the shares changed hands the same day.
OPTiM did not disclose the price or the size of the stake it now holds. It called the purchase its first merger or acquisition in the medical field.
According to the release, MediTech's Drs'HotLine service will keep running, and the two companies will share their customer bases. OPTiM did not say whether MediTech's management or staff will change, or whether the product's name or pricing will be altered.
What MediTech built
MediTech was founded on March 30, 2018, and is based in Shibamata in Tokyo's Katsushika ward. It also has an office in Ino, Kochi Prefecture. Its representative is Kazuhiro Hiyama. The company describes its work as medical systems and medical consulting, and its stated mission is to bring about a time when anyone in the world can receive good medical care.
Its main product, Drs'HotLine, is a certified medical image sharing program. MediTech says doctors built it. A hospital captures DICOM images, the standard format for scans, and sends them through the app to a cloud server. A consulting doctor somewhere else then views them on a smartphone. The company pitches it as low-cost and simple enough for any facility with an internet connection.
The OPTiM release lists security features that include two-factor login, automatic removal of personal data embedded in image files, and a block on downloading images to the receiving phone. MediTech says the app can speed up transfers between hospitals, avoid unnecessary transfers, reduce the risk of misdiagnosis and make it easier to get a specialist's opinion. It also says the app can ease the on-call load on doctors.
The release says many medical institutions use the service but gives no number. MediTech says the product was chosen for a Kochi Prefecture subsidy for healthcare demonstration projects in fiscal 2024. In November 2025, the company won an encouragement award at the 8th Shikoku Alliance business plan contest.
OPTiM was already a shareholder
The acquisition follows an earlier investment by OPTiM's own fund. In May 2025, the Digital Transformation Fund Investment Limited Partnership No. 1 said it would invest ¥30.15 million (about $200,000) in MediTech by subscribing for new common shares, with payment planned for the end of that month. The fund is run by OPTiM Bank Technologies, an OPTiM subsidiary. At the time, the two sides described the aim as combining OPTiM's AI and IoT technology with MediTech's image sharing know-how.
That is the only outside funding round reported for MediTech. A STARTUP LOG profile of the deal gives MediTech's capital as ¥40.15 million (about $265,000). Neither company disclosed MediTech's revenue, total funding raised or headcount.
Why OPTiM is buying
OPTiM tied the deal to pressure on Japanese healthcare: rising demand, a shortage of specialists, uneven care between regions and heavy workloads for medical staff. It also pointed to a government roadmap that aims to have most medical institutions using electronic health records, and sharing information between facilities, by 2030. OPTiM sees image sharing between hospitals as a growth area within that plan.
The company listed four plans for the combined business. The first is to build AI-assisted diagnostic support services on top of MediTech's image sharing. The second is to fold Drs'HotLine into OPTiM AI Hospital Suite, OPTiM's set of products for hospitals. A hospital worker could then use one smartphone for internal calls through OPTiM AI Hospital Phone and for sending images to other facilities, with the device managed by OPTiM's mobile device management software.
The third plan is cross-selling. OPTiM will sell Drs'HotLine through its sales partners and existing customers, and MediTech's hospital relationships will be used to sell OPTiM's hospital products, with the aim of building recurring revenue. The fourth is regional and remote care: image sharing during emergency transport, remote reading of scans and specialist consultations. This would include work with local governments and core regional hospitals in Saga Prefecture. OPTiM lists an office in Saga among its locations.
What comes next
OPTiM gave no forecast for the deal's effect on its earnings and did not say when the first combined products would ship. M&A Online, which tracks Japanese deals, listed the purchase among OPTiM's moves to expand its medical business.
For MediTech, the deal turns an investor from 2025 into its parent company about 18 months later. For OPTiM, it adds a certified clinical product and a base of hospital customers to its AI hospital suite.
