Company
A name that says how we work.
Statquoia combines statistics and sequoias — the world's tallest and longest-living trees. Like the rings of a sequoia, good statistical work records time honestly and holds up under scrutiny for decades.
Founded in 2025 and now incorporated as Statquoia AB, a registered limited company in Sweden, we build robust statistical practices that generate lasting impact in medical research, epidemiology, HEOR, and HTA.
We are an AI-empowered company, integrating the latest AI models, Anthropic Claude and Google Gemini, to accelerate statistical programming, documentation, and literature review. Every analysis and result is designed, validated, and quality-controlled.
