FUKUOKA, Japan, May 8, 2025 /PRNewswire/ -- Medmain Inc., a Japanese medtech startup that offers PidPort, an AI-powered cloud system to assist in digital pathology, is pleased to announce that it has raised 3.3 million USD through a third-party allotment of shares, with One Capital as the lead investor and Niremia Collective and Plug and Play as additional participants. With this round, the company's total equity funding has reached 18 million USD.

About Medmain Inc.

Medmain Inc. is a Japanese medtech startup with the corporate mission "To create a world where medical services can be accessed with technology anywhere, anytime". As a partner to medical professionals around the world, the company develops and provides PidPort, an AI-powered cloud system that supports digital pathology. Learn more at: https://en.medmain.com

Medmain has been providing a full range of services in the field of digital pathology, starting with a digitization service for specimen slides, to remote diagnosis support that connects remote facilities via cloud computing, to the presentation of high accuracy and rapid analysis of pathology results using AI, all of which are utilized at many facilities. We have also succeeded in accelerating the speed of development of pathology AI, our core technology, by creating a proprietary platform that accelerates AI development by means of transfer learning.

  • Purpose and Background of the Fundraising (Challenges Medmain Aims to Address) 

The funds raised will be used to further enhance the development of our product "PidPort," invest in infrastructure for digitalization, strengthen our sales organization, apply for regulatory approval of our pathology AI, and build a foundation for international expansion.

With the global increase in cancer diagnoses, the number of pathology examinations has also risen significantly, leading to a chronic shortage of personnel and placing a heavy workload on medical institutions. Traditionally, pathology diagnoses have long relied on physical glass slides, but at Medmain, we have been supporting medical institutions through the provision of digital services and our platform, "PidPort."

PidPort is currently used by many clients in a wide range of settings, including remote diagnostic support and consultations between medical institutions, multi-facility conferences, academic conferences, educational use in lectures and training sessions, as well as research and quality control at universities and corporations.

Moving forward, we will continue to enhance functionality and strengthen integration with surrounding systems to further improve service convenience. At the same time, we are committed to expanding support and value delivery to more medical sites, and to strengthening our organizational structure in preparation for global expansion.

LAS VEGAS, Jan. 12, 2026 /PRNewswire/ -- Roborock, the global leader in home robotics engineered to simplify daily life, became the most awarded Robotic Vacuum Brand at CES 2026, after announcing its new product line-up for the first half of the year. Under the theme "The Greatest Meeting the Greatest", the brand's keynote presentation led by Roborock's President, Quan Gang, unveiled the Saros Rover, the world's first robotic vacuum with AI-powered wheel-leg architecture that can both navigate stairs and slopes with human-like agility while cleaning them.

Announcements also included the Roborock Saros 20, Roborock Saros 20 Sonic, Roborock F25 ACE Pro, and Roborock Qrevo Curv 2 Flow. These launches happened in partnership with Real Madrid Football Club for the Vacuum Cleaner category, announced ahead of the show's starting date.

Roborock also announced separate to the Real Madrid partnership its entry into the US market for lawnmower products, including the new RockMow X1 LiDAR. Consumers, clients, and interested parties can visit Roborock's Booth #52632 at Venetian Expo CES 2026 from January 6 to January 9th during show hours.

Roborock Saros Rover - The World's First Wheel-Leg Robovac

In a world-first, Roborock introduced at CES 2026 the Roborock Saros Rover, featuring the world's first two-wheel-leg architecture in a robovac. Each wheel-leg provides reach, lift, height, and imitates human mobility, enabling the robot to raise and lower each one of the wheel-legs independently, execute small jumps, agile turns, sudden stops, and directional changes, all while maintaining a level body as the ground changes.

At a software level, Saros Rover harnesses the power of Artificial Intelligence algorithms, in conjunction with complex motion sensors and 3D spatial information to understand its environment and make its wheel-legs react with precision.

The Saros Rover excels in multi-storey homes, where it is able to clean each one of the steps of a staircase as it goes to the second floor, dramatically reducing "no-go" zones and transitioning into cleaning areas previously inaccessible for homes with a single robovac.

The Saros Rover is able to tackle several types of non-flat surfaces, with staircases being the most obvious one. This includes not only traditional staircases but also curved staircases, or even carpeted staircases with bullnose fronts, all while cleaning each one of their steps as it navigates through them. Other types of surfaces that Saros Rover is able to tackle include slopes as well as complex multi-level room thresholds requiring height and power.  Saros Rover is a real product in development with an unconfirmed launch date.

The Greatest Meeting The Greatest - Roborock and Real Madrid Football Club join hands

Announced days before the show's beginning, Roborock presents at CES its first activation within the strategic global partnership with Real Madrid Football Club's First Men and First Women teams, widely ranked as one of the greatest football clubs in history. The partnership is solely related to Roborock's extensive portfolio of Vacuum Cleaner products and excludes other product lines from the brand. Under the umbrella theme of "The Greatest Meeting The Greatest", the partnership responds to a deep affinity between the brand ethos of both organizations, which have achieved remarkable historical performance with innovation as common denominator. The partnership will bring Roborock's smart-cleaning innovations to life through stadium exposure, campaigns and player-led storytelling that translate the meaning of "Real Smart Cleaning" from the pitch to the home.

Roborock's early 2026 Robovac line-up: Roborock Saros 20, Roborock Saros 20 Sonic, and Roborock Qrevo Curv 2 Flow

At its keynote, Clarbi Lu, product marketing lead at Roborock, unveiled new smart cleaning products launching in the first half of the year. Leading the lineup are the Roborock Saros 20 and Roborock Saros 20 Sonic, the latest flagship models in the Saros Series. Saros 20 upgrades the StarSight™ Autonomous System 2.0 with enhanced AI object recognition and a new AdaptiLift Chassis 3.0 for improved threshold climbing. Saros 20 Sonic adds RetractSense™ Navigation, an ultra-slim body, and the VibraRise® 5.0 Mopping System. Both use a 35,000 Pa HyperForce® motor and a new RockDock®. The Qrevo Series also expands with the Roborock Qrevo Curv 2 Flow.

Rockmow X1 LiDAR, X1, RockNeo Q1 lead the Roborock North American Roll-Out of Lawnmowers

Roborock has announced its North American expansion into the lawnmower category with three key models. The flagship RockMow X1 LiDAR features Sentisphere™ LiDAR Environmental Perception, 4WD traction, and Active Steering for flawless coverage. Alternatively, the RockMow X1 utilizes RTK and VSLAM navigation alongside a Dynamic Suspension System for industry-leading edge cutting. For smaller gardens, the entry-level RockNeo Q1 makes smart care accessible by combining RTK + VSLAM navigation with Stereo Vision Obstacle Avoidance.
