Key Requirements

Proven ability to build financial models from scratch (operating models, unit economics, margin analysis)

High attention to accuracy — must be detail-oriented with numbers and invoices

Teiko is building the Artificial Immunologist. With 500M+ years in the making, the immune system is nature’s original fine-tuned model. We are building a foundational laboratory to digitize this system and reshape multi-billion dollar markets across clinical trials, oncology, autoimmune diagnostics, prenatal medicine, surgical recovery, and aging.

By capturing high-resolution immune snapshots, we give drug developers and doctors the decisive signal they need to predict whether a $200M+ clinical trial succeeds, whether a therapy will cause irreversible harm, or whether a patient will respond to a crucial drug. Through deep technical breakthroughs, we have cracked the key challenges that have held back immune profiling from achieving clinical-grade scale.

Today we power 30+ trials for Genentech, Recursion, iOnctura, Obsidian, and many more. Revenue has grown explosively because we solve critical problems that have bedeviled drug developers and doctors for years. Our interdisciplinary team brings together pioneers and experts in immunology, advanced diagnostics, and machine learning.
