What Big Health does

Big Health is a privately held digital therapeutics company founded in 2010 and headquartered in San Francisco, with additional UK operations in London. The company develops mobile applications that deliver evidence-based cognitive behavioral therapy (CBT) for three common mental health conditions: insomnia, generalized anxiety disorder, and depression. Its core technology consists of automated, algorithm-driven personalization of CBT content delivered via video, audio lessons, and interactive exercises adapted based on user symptoms and daily tracking. The product portfolio is bifurcated between FDA-cleared prescription digital therapeutics (SleepioRx for chronic insomnia in adults 18+, cleared August 2024; DaylightRx for GAD in adults 22+, cleared September 2024) and consumer-facing wellness versions (Sleepio, Daylight, Spark Direct) available without prescription. The company supports its clinical claims with 100+ peer-reviewed publications, 22 randomized controlled trials involving 28,000+ participants, and references in guidelines from the American College of Physicians, British Association for Psychopharmacology, European Sleep Research Society, and NICE.

The company generates revenue through four primary streams: enterprise SaaS subscriptions with health systems, health plans, and employers priced per covered life or employee count; one-time prescription licenses for 90-day treatment courses billable through new CMS Digital Mental Health Treatment codes (G0552, G0553, G0554); PBM/formulary billing pioneered via the Evernorth Digital Health Formulary (Cigna); and freemium consumer app downloads. Distribution spans direct enterprise field sales, channel partners (PBMs, health plans), the NHS Scotland national program covering 5M+ adults, and App Store/Google Play. Named customers include Henry Ford Health, Northwell Health, Cleveland Clinic, Cigna Healthcare, The Hartford, Aramark, and NHS Scotland. The company has raised approximately $98.7M in total funding across a $75M Series C led by SoftBank Vision Fund 2 (January 2022) and a $23.7M strategic round co-led by .406 Ventures and AlleyCorp (February 2026), and currently employs 101-250 people with the majority working remotely.

Revenue model

1. Prescription Digital Therapeutic Licensing: One-time payment per patient for 90-day course of treatment, delivered as prescription digital therapeutic. Providers purchase licenses and bill through new CMS Digital Mental Health Treatment (DMHT) codes (G0552, G0553, G0554). 'Buy and bill' model mirrors clinic-administered drugs.
2. Enterprise/B2B SaaS Subscriptions: Annual or multi-year contracts with health plans, employers, and health systems for population-wide access to digital therapeutics. Pricing based on covered lives or employee count.
3. PBM/Pharmacy Benefit Manager Billing: Pioneered ability to bill through pharmacy benefit managers, enabling employers and health plans to add Big Health to formulary and pay via drug claim - same mechanism as medications.
4. Consumer App (OTC): Consumer wellness apps (Sleepio, Daylight, Spark Direct) available without prescription for direct consumer download and use.

Recent moves8 records

Expansion highlights6 records

Direct peers

• Akili Interactive: Akili Interactive is another FDA-cleared prescription digital therapeutics company, focusing on cognitive disorders (ADHD, cognitive dysfunction in MS) rather than mental health. Both companies are direct peers in the prescription DTx category, share FDA-clearance-based business models, and compete for the same payer and provider mindshare in the nascent prescription digital therapeutics space.
• Pear Therapeutics: Pear Therapeutics was a pioneering FDA-cleared prescription digital therapeutics company (reSET, reSET-O, Pear-008) for substance use disorder and insomnia before filing for bankruptcy in 2023. It is a direct historical peer in the prescription DTx space, and its bankruptcy is a cautionary comparable for Big Health's commercial trajectory in the same regulatory and reimbursement environment.
• Lyra Health: Lyra Health is a mental health benefits platform offering therapy, coaching, and digital self-care to employers and health plans. It is comparable to Big Health's enterprise employer and health plan channel, competing for the same mental health benefit budget and serving overlapping customer populations with adjacent evidence-based interventions.
• Spring Health: Spring Health is a mental health benefits platform combining provider matching, therapy, coaching, and digital exercises for employer and health plan customers. It competes with Big Health's employer and health plan offering for the same population-level contracts and overlapping customers in the employer-sponsored mental health benefits market.

Broad incumbents

• Headspace Health: Headspace Health (formed via the Headspace-Ginger merger) is a broader mental health and wellness platform offering meditation, coaching, and therapy services to consumers, employers, and health plans. It competes with Big Health's Sleepio and Daylight consumer and employer offerings, particularly for employer wellness budget and health plan mental health benefit dollars.
• Calm: Calm is a leading consumer wellness and meditation app with strong employer and health plan distribution for sleep and anxiety content. It competes directly with Big Health's consumer Sleepio and Daylight apps for app store mindshare, employer benefit placement, and health plan partnerships serving the same insomnia and anxiety populations.
• Talkspace: Talkspace is a publicly traded online therapy and behavioral health platform serving B2B (employers, health plans) and direct-to-consumer markets. It is comparable to Big Health on the health plan and employer channel but offers live therapist-led care rather than fully automated digital CBT, positioning it as a complementary or competing modality in payer mental health contracts.
• Omada Health: Omada Health is a virtual care company delivering digital behavioral interventions for chronic conditions (diabetes prevention, hypertension, musculoskeletal) to employers and health plans. It is comparable to Big Health as a digital therapeutic employer and health plan platform with similar evidence-based, payer-reimbursed delivery model serving overlapping B2B customers.

Emerging players

• Cerebral: Cerebral is an online mental health platform providing medication management and therapy for anxiety, depression, and ADHD. It serves some overlapping customer segments (employers, direct consumers) and addresses overlapping indications (anxiety, depression), making it a partial competitor for health plan and employer mental health benefit dollars alongside Big Health's digital therapeutic interventions.
• Woebot Health: Woebot Health is an AI-powered conversational mental health platform delivering CBT-based chatbot interventions for anxiety and depression. It is comparable to Big Health on the digital CBT delivery model and overlapping indications (anxiety, depression) and competes for similar employer, health plan, and consumer audiences with a different technological approach (AI chatbot vs. structured curriculum).
