Role overview
Superpower is a preventive-health and longevity-focused digital clinic that operates via the premium domain superpower.com, offering an all‑in‑one health membership built around advanced biomarker testing, continuous monitoring, and concierge-level clinical support.[1][3][5][11][17][22][35] The platform transforms traditional annual or episodic physicals into a continuous, data-driven health program by conducting comprehensive lab panels that cover 100+ biomarkers across roughly 17 core body systems (including heart, thyroid, hormones, toxins, genetics, microbiome, metabolic health, and more), then generating health scores, biological-age estimates, and personalized care plans.[5][11][16][17][22][35][43] Members typically pay an annual subscription (recently promoted at around $199 per year in most states) that bundles: biannual or periodic blood testing; aggregation of health data (lab results, prior medical records, wearables, and family history) into a unified dashboard; and text or chat access to a concierge medical team supported by an AI health advisor that explains results, identifies risks, and recommends optimization strategies.[1][5][11][14][16][17][19][35][43] Superpower positions itself as a “health super app” and “world’s first all‑in‑one health membership,” aiming to democratize concierge-level preventative care by making deep biomarker testing, longevity-focused clinical expertise, and a curated marketplace of health products and services accessible at a relatively low flat membership fee.[11][16][17][19][22][35][37][43] According to CB Insights, Sacra, and other startup intelligence sources, Superpower was founded around 2023, operates within the personal health / digital clinic segment, and is headquartered in Los Angeles, California, with operations and marketing also tied to broader U.S. markets such as San Francisco and New York.[3][5][8][11][22][27][43] The company has raised multiple funding rounds (including a $4M pre‑seed and a $30M Series A reported by Forbes and company communications) from venture investors focused on consumer health, longevity, and technology, and continues to expand its subscription concierge model that integrates lab diagnostics, clinician access, prescription and health-product fulfillment, and AI‑driven health guidance into one unified platform.[3][10][13][17][22][27][35]
