What would a healthcare system freed from the yoke of history look like?

It would be outcome-driven, certainly. Propelled by human dignity rather than by profit. Upheld by a network of compassionate experts actively working to increase medical literacy for all. How would you do it? You would open the doors for any patient to be able to work with experts who can simply help—people who know how to interact with the legacy system and know the magic words to get patients exactly what they need, when they need it. You would build a fortress of hope within the U.S. healthcare system.

That’s what we’re doing at Solace. Solace is a healthcare advocacy marketplace that connects patients and families to experts who help them understand and take charge of their personal health.

Our current stack is Typescript, React, Postgres, Heroku.
