  • - Jesse & Aegis: senior technical owner, improve systems, extract shared foundations across context, retrieval, memory, orchestration, tools, state, and escalation.
  • - Evals & Experimentation: build trustworthy benchmarks, establish path from offline evaluation to controlled production experiments.
  • - Production Learning Loop: translate traces and outcomes into better evals, architecture, models, and platform capabilities.
  • - Safety & Compliance: ensure safety through authorization, validation, idempotency, auditability, recovery, and regional/privacy requirements.
  • - Models & Economics: own model selection, routing, fallbacks, caching; lead data prep, fine-tuning, evaluation, and deployment of open-weight models when warranted.
  • - Reliability: own shared runtime in production, tracing, observability, testing, capacity, incident response.

About AIOS

Building AI-native infrastructure for the next era of care.

Our overarching mission is to build the AI operating system for consumer healthcare - delivering end-to-end care with near-zero marginal human time. We believe the future of healthcare is automated, intelligent, radically lower cost, and built around the consumer. We believe biology is entering a golden age. We believe profitable, focused companies beat bloated ones. We're determined to get the humans out of healthcare - replacing slow, expensive, legacy workflows with software-driven care delivered at scale. We’ve started by building this infrastructure to power our own brands - including Bolt Pharmacy and Fella Health, among others. Today, that infrastructure is helping patients access life-changing treatment for excess bodyweight. Over time, we’ll extend it across many of the categories that will define the next era of healthcare. Our infrastructure will have served 100 million patients worldwide by 2035. We’ll then use that infrastructure to deliver next-generation healthcare products at massive scale. In doing so, we aim to build the world’s first trillion-dollar healthcare company.
