FRONTIER AI
FOR AGENTS THAT PERSIST.
SCROLL
001THE LAB
WE BUILD THE MODEL STACK BEHIND PERSISTENT AGENTS.
Forerunner is a frontier AI research lab. We build the model stack behind agentic systems — perception, persistent memory, real-time voice, and the long-horizon reasoning that keeps an agent coherent across thousands of turns.
Mirari is that stack, productized. The same models power our own app and ship to developers through one API — so the research runs in production, at scale.
002Products
Three products. One research stack.
The lab’s work ships as products people use every day.
HealthPass
Your health record, ready when it matters.
Medical ID, allergies, and vitals in one encrypted pass. Show it to a care provider in a tap — on your terms — or keep it in Apple Wallet.
- Encrypted medical ID
- You choose what to share
- Vitals on your wrist
Friday
macOS · WindowsHand off the work that repeats.
An always-on agent that absorbs the recurring load — triage, digests, follow-ups, monitoring — and shows you what it costs while it runs.
- Takes on the work that recurs
- A live meter, not a surprise bill
- Always on, even while you sleep
