Junction Powers GRAIL Cancer Screenings and Expands Health Data Infrastructure
Junction announced a collaboration with GRAIL to support access to the Galleri multi-cancer early detection test across digital health platforms, as reported by PR Newswire. Healthcare organizations can order the blood test directly through Junction's infrastructure, which provides multi-state clinical operations, integrated physician networks, and automated test coordination across care delivery channels.
The partnership builds on a year of expanding diagnostic volume. As reported by TechCrunch, Junction raised an $18 million Series A round led by Creandum, with participation from Point Nine, Amino Collective, and Y Combinator. The company connects digital health apps to lab test networks and more than 500 wearable devices, routing data through a unified API.
Unifying Wearables and Lab Testing
Founded in 2020 as Vital, Junction began by standardizing health data pulled from consumer and medical wearables. It subsequently expanded into diagnostics logistics, enabling virtual care platforms to order in-person and at-home lab tests across all 50 U.S. states.
Speaking on a Hint Health panel, founder Maitham Dib explained that lab testing frequently runs into operational failures, noting that 10% to 20% of orders require manual intervention from clinical staff to trace missing results or resolve misconfigurations. Junction operates a dedicated operations team and software rules to handle those edge cases. For instance, when high-biomarker orders require seven to nine blood tubes, failure rates in mobile phlebotomy climb to 25%, prompting the company to build algorithmic routing that directs patients to draw sites instead.
Today, Junction counts more than 140 healthcare organizations as customers, including Parsley Health, Evidation, and Found. Its platform manages connections to over 2 million devices and processes lab tests across more than 10 lab networks.
Founded by Engineering Operators
Junction was founded by Maitham Dib and Femi Awomosu. Dib began his career as an aerospace engineer working on vertical takeoff control systems before joining Babylon Health, where he worked on machine learning and wearable data integrations. While dealing with personal chronic health issues and watching Babylon build fragmented at-home testing products, Dib identified the need for a dedicated developer infrastructure layer in healthcare.
In a video interview on Aakash Shah | healthcare explained, Dib described Junction as building the Twilio model for healthcare. Instead of each digital health startup managing direct logistics, state-level lab requisition paperwork, and custom device integrations, Junction packages lab ordering, specimen collection, and standardized data streaming into single API calls.
Hiring Across Engineering and Commercial Teams
Junction operates with a team of 19 employees and is adding staff across engineering, modeling, and commercial sales to support its diagnostics workflows and client onboarding.
On the technical side, the company is hiring a Data Scientist ($180,000–$220,000, remote US) to lead statistical modeling, experimentation, and evaluation across clinical diagnostics workflows and AI-enabled product lines. For core product development, Junction is recruiting a Product Engineer / Fullstack Engineer (£90,000–£130,000, remote UK/Portugal) to construct the next iteration of its diagnostics API and client-facing dashboards using Python (FastAPI), TypeScript, React, and Google Cloud Platform.
To drive revenue with digital health providers, health systems, and electronic medical record vendors, the commercial team is expanding. Junction is hiring a Sales Development Representative ($70,000–$100,000, New York) as the third SDR on a five-person sales unit, focusing on outbound outreach with Clay and automated workflows. The company is also seeking Account Executives [all levels] ($120,000–$145,000, New York remote/hybrid) reporting to the Head of Commercial to close new business ARR across SMB and enterprise accounts.
