What goes into it

Sleep is one of the domains established depression assessments such as the PHQ-9 ask about, alongside mood and energy. 1

When your body tells a different story
What you tell yourself
“I’m fine, just busy.”
What your body shows
- Sleep off for a week
- Heart rate variability trending down
- Resting heart rate up for days
Siggy points out the gap between the two, so you and your clinician can talk about it early. Over time, the patterns may help you spot hard stretches sooner.
How it grows with you
- Day 1A starting point
Your first check-in sets the baseline. Medication and goals join as they become part of your care.
- Every check-inYour own baseline
Changes are read against your own history, and missing days stay visible rather than filled in.
- Over timeA shared language
The number, its history and the conversation around it help you and your care team see what is changing.

Founders
Our founders.
Jonathan Sabbagh
Co-Founder
Jonathan’s path to Siggy began with his own PTSD diagnosis. After psychedelics saved his life, he returned to school at 38 to become a therapist and founded Journey Clinical, the world’s largest provider of psychedelic-assisted therapy. Its network of more than 3,000 therapists has delivered over 1.5 million hours of ketamine-assisted therapy, with 90% of patients improving and 40% no longer meeting the criteria for their diagnosis. Journey Clinical also partners with leading drug developers, including Compass Pathways. Jonathan saw firsthand how transformative great care can be and how few people have access to it. Today, he’s building Siggy to use AI for good and bring world class mental healthcare to everyone everywhere.
Edvard Engesaeth, MD
Co-Founder
After training as a physician, Edvard was struck by how broken and inaccessible healthcare had become. He co-founded Nurx, a pioneer of mobile telehealth that delivered care and prescriptions directly to patients, scaling to more than 2 million patients and raising over $100M before it was acquired. With Siggy, he's applying that same playbook to the hardest access problem in medicine: mental health.
