About Big Health

Big Health is a pioneering digital therapeutics company focused on delivering evidence-based, non-drug treatments for common mental health conditions such as insomnia, anxiety, and depression. Their flagship products, Sleepio and Daylight, utilize cognitive behavioral therapy (CBT) techniques delivered through digital platforms. These programs are designed to be scalable, accessible, and consistent, offering an alternative to traditional medication-based approaches. Big Health’s solutions are backed by rigorous research, including numerous peer-reviewed studies and randomized controlled trials, and are cited in leading clinical guidelines.

For physicians, Big Health’s offerings provide a valuable tool to address the significant demand for mental health support, especially given the challenges of access to in-person or teletherapy. The company’s digital therapeutics are FDA-cleared for certain conditions, such as SleepioRx for insomnia disorder and DaylightRx for generalized anxiety disorder, and are increasingly integrated into clinical workflows with established reimbursement pathways. Big Health partners with health systems, health plans, employers, and providers to offer these programs, aiming to improve outcomes, reduce healthcare costs, and expand access to care for diverse populations, including those traditionally underserved. They also recently expanded into adolescent mental health through the acquisition of Limbix and Freespira, addressing adolescent depression and panic disorders.

Their digital therapeutics, such as Sleepio and Daylight, are backed by numerous peer-reviewed studies and randomized controlled trials, offering safe and effective non-drug alternatives for common mental health conditions like insomnia, anxiety, and depression. The programs are designed by leading clinical experts and deliver gold-standard care, specifically Cognitive Behavioral Therapy (CBT), in an accessible and scalable format. This can be particularly beneficial for addressing long waiting times for traditional CBT. The expansion into adolescent mental health with SparkRx also provides much-needed evidence-based options for younger patients. Physicians can trust Big Health's offerings as clinically validated tools that can complement existing treatment plans and improve patient access to care.

Big Health's integration with payers and employers is a significant aspect of its distribution, providing reimbursed access to over 12 million people globally. They also aim to deepen PBM/insurer integrations and explore API integrations with 'super-platforms' and device makers. The broader healthcare technology stack often involves integrations with Electronic Health Records (EHRs) and utilizes cloud platforms (AWS, Azure, Google Cloud) which support various healthcare data exchanges and interoperability standards like FHIR. This suggests a strategic direction towards seamless integration within the wider healthcare ecosystem.
