PathAI

Overview

PathAI is a Boston-based company aiming to improve cancer diagnosis accuracy using AI. Its models analyze pathology images (digital tissue samples) to help pathologists detect patterns and abnormalities. In May 2026, Roche agreed to acquire PathAI for up to $1.05 billion ($750M upfront plus up to $300M in milestone payments), with closing expected in the second half of 2026.

Key Features

AISight Dx (Digital Pathology Platform)

A cloud-based digital pathology platform that lets pathologists view and manage slides digitally and applies AI to key diagnostic steps. It holds FDA 510(k) clearance for use in primary diagnosis, and in February 2026 Labcorp expanded its agreement to deploy it across its national network of anatomic pathology labs and hospital collaborations.

AI Pathology Image Analysis

Analyzes digitized tissue samples to detect:

• Cancer cells
• Tumor boundaries
• Cell abnormalities
• Treatment efficacy assessment

Pathologist Assistance

AI augments pathologists' eyes to catch patterns humans might miss, enabling diagnostic double-checks.

In Development

PathAssist Derm, an AI solution for dermatopathology, received FDA Breakthrough Device Designation in March 2026.

Pharma Collaborations

Used for biomarker discovery, clinical trial pathology evaluation, and companion diagnostic algorithms. PathAI has worked with Roche since 2021, expanding in 2024 to co-develop AI-enabled diagnostic algorithms.
