"Partnering with Sonde has definitely accelerated our initiatives in many ways. What we're learning here is that we can give people insights on how they can understand their bodies and we can put metrics to the brain in a way that we previously haven't been able to... I think Sonde has been a really great use case for what external innovation can be."
