Healthcare social network Inspire has reached the milestone of one million registered members.

“It’s gratifying and humbling to see the community’s growth,” said Brian Loew, co-founder and CEO of Inspire. “We see it as a testament to the wisdom of empowered patients and caregivers who are leading a movement toward patient-centered care.”

Inspire is known for not just the size of the community but for the activity of the patients and caregivers interacting in more than 200 online groups. Last year, Inspire reached another milestone of one billion words written by its community members.

“The rate at which members are finding and joining Inspire is accelerating exponentially,” said Richard Tsai, VP of marketing at Inspire. “Patients and caregivers across several thousand reported conditions are writing about their experiences, and generating relevant language that others who are facing similar experience can find.”

This sharing of information can be particularly useful for rare disease patients who often have trouble getting an accurate diagnosis, and for cancer patients who are in dire need of support to make the best possible treatment decisions.

Loew noted that Inspire is adding more communities and nonprofit partners regularly. “While we have more improvements planned for our online platform,” he added, “we are committed to ensuring that the focus will continue to be on the wonderful patients and caregivers who share and connect with each other every day in our community.”
