Pink Elephant builds infrastructure of products at the frontier of mental health on EU&US markets. Mental health is a global crisis hiding in plain sight. Nearly 1 in 8 people live with a mental disorder. Depression and anxiety alone strip $1 trillion from the global economy every year. Conventional treatment leaves most patients cycling through mediocre solutions for years - undertreated, undersupported, and underinformed. Progressive therapies are showing results up to 10 times more effective than standard care. Yet fewer than 5% of people can access them. We're here to close that gap. A big part of our portfolio is everyday mental healthcare - mental health diagnostics, antidepressant journeys, the unmet clinical touchpoints, the patients who leave a 20-minute appointment with a prescription and no roadmap. The Product Claro - an early-stage AI mental health product supporting people taking antidepressants.The product helps users track progress, understand side effects, prepare for doctor visits, and make the treatment journey clearer and less isolating. Today Claro includes three core engineering domains: <ul> <li>Backend - patient-facing FastAPI backend for auth, onboarding, check-ins, chat, reports, notifications, and admin tools.</li> <li>AI Services - AI recommendation engine with RAG-grounded LLM pipelines, clinical decision logic, job processing, and safety guardrails.</li> <li>Mobile - native iOS app built with SwiftUI and a Kotlin Multiplatform shared business layer.</li> </ul> We are building at the intersection of consumer health, clinical workflows, AI companionship, and sensitive personal data.
