Where it all began

Shardi Nahavandi couldn’t drink water, she couldn’t see, her hair was falling out. When doctors couldn't find anything, they dismissed her symptoms as stress.

Set on uncovering the answers herself, she pursued master’s degrees in Health Technology and Endocrinology. Countless research papers later, she found it— a hormone imbalance.

Ignited by her passion to help women understand their hormones better, Shardi started Tuune.

Evidence-based technology built with empathy

We work with (not against) the research and medical community to enact real change in womens’ healthcare effectively and efficiently.
