Two Seattle healthcare companies are joining forces to build tech-infused solutions together.

Samepage Health has acquired Health123, a Seattle-based startup that launched in 2011 and created a healthcare intelligence management platform.

Founded by University of Washington professor Paul Ciechanowski, Samepage has been around for several years and sells online tools to help professionals treat patients with multiple behavior health and medical conditions. The idea is to reduce money that delivery networks, medical groups and payers spend on complex chronic patients, while improving the quality of the care.

Now Samepage will utilize Health123’s platform. Health123 co-founder Rebecca Norlander, a former Microsoft executive, is now CEO of Samepage. Her two colleagues, CTO Walt Jones and COO Rachel Lanham, will also join the company, which will employ around 10 people after the acquisition.

Norlander said the Health123 platform can be a “force multiplier” for Samepage’s existing Samepage Method product, which is used by clients like Mayo Clinic, NYC Health and Hospitals Corporation, and Trinity Health.

“Samepage has built a vibrant services-based business, but wants to take it to the next level with technology to create the one-two punch of services powered by scalable platform technologies — that’s where Health123 comes in,” Norlander told GeekWire.

Terms of the acquisition were not disclosed.

“We are thrilled to welcome Health123’s talented and innovative leadership and personnel to join the Samepage team,” Ciechanowski said in a statement. “By leveraging their proven platform, we will be able to bring our successful solution to more customers quickly, and more deeply engage patients on their terms while better supporting clinicians.”
