Big Health is a digital therapeutics company that develops evidence-based, non-drug digital programs for common mental health conditions like insomnia, anxiety, and depression.[1][2][3][5] Its flagship products—Sleepio for insomnia, Daylight for anxiety, and SparkRx (now Spark Direct) for adolescent depression—deliver cognitive behavioral therapy (CBT) via smartphones and are FDA-cleared, reimbursable, and backed by over 80 peer-reviewed studies.[2][3][5] Serving health systems, health plans, employers, and providers, Big Health addresses access barriers to mental health care by offering scalable, side-effect-free alternatives to medication, with $129.3M raised in funding (latest $75M Series C in 2022) and strong growth momentum including the 2023 acquisition of Limbix to expand into youth mental health.[1][2][4]
Big Health was founded in 2010 in San Francisco by Peter Hames and Dr. Colin Espie after Hames struggled with insomnia and found relief through Espie's book on CBT for sleep, realizing the potential to scale this non-drug approach digitally.[1][3] Hames, driven by personal experience with limited treatment options beyond pills, partnered with Espie, a leading sleep expert, to create accessible digital programs.[3] Early traction came from rigorous clinical validation, evolving into a platform with peer-reviewed evidence; key milestones include launching Sleepio, Daylight, and the Limbix acquisition in 2023, which added teen-focused SparkRx and boosted adolescent offerings.[2][3] Leadership has included CEO Arun Gupta (ex-Quartet Health founder) and recently Yael Berman as new CEO to drive growth.[2][3]
Big Health stands out in digital mental health through:
Big Health rides the digital therapeutics wave in mental health, capitalizing on post-pandemic demand for accessible, non-pharmacological care amid clinician shortages and youth mental health crises.[1][2] Timing aligns with FDA clearances for digital CBT and payer reimbursements, fueled by market forces like rising insomnia/anxiety prevalence and employer wellness priorities.[1][5] It influences the ecosystem by pioneering scalable CBT (e.g., leading ESP matrices with ResMed, Inspire), partnering for integrated platforms, and expanding evidence-based alternatives, reducing reliance on meds and bridging gaps in traditional care.[1][2][4]
Big Health is poised for accelerated growth under new CEO Yael Berman, leveraging its adolescent pipeline (e.g., upcoming teen anxiety product) and partnerships to capture more of the $15.7M-revenue digital health market.[3][4] Trends like AI-enhanced personalization, broader reimbursements, and hybrid care models will shape its path, potentially driving higher enrollment and Mosaic Score recovery from recent dips.[1][2] Its influence may evolve by setting standards for non-drug mental health tech, helping millions as it scales globally—echoing its founding mission to transform access beyond pills.[3]
Big Health has raised $149.7M across 4 funding rounds. Most recently, it raised $23.7M Venture Round in February 2026.
