The Infrastructure Layer for Domain-Specialist AI Agents

I. The Problem

Autonomous AI agents are being deployed across research labs, financial firms, logistics operations, and legal teams. Across all of them, the failure mode is the same: they are stateless. Every session starts from zero. No memory of what happened yesterday, last week, or last year. No record of prior decisions, no institutional continuity.

This is not a model problem. The models are capable. The problem is infrastructure — the absence of persistent memory, structured messaging, and monitoring designed for autonomous agents rather than for stateless API calls.

Every company running AI agents in production is running them on infrastructure that was never designed for them. The tooling assumes sessions. The tooling assumes humans in the loop. The tooling assumes the agent will not need to remember anything past context window.

II. The Market
$150B+
Addressable market across seven verticals

Every company running AI agents is a potential customer. The infrastructure layer for agent memory and messaging is winner-take-most. Whoever builds the persistent substrate first — and makes it domain-specific — becomes the default plumbing for production AI.

Probe targets academic research markets ($3B+ institutional software spend). Mandate is timed against the Colorado AI Act deadline (June 30, 2026), creating immediate regulatory urgency across enterprise customers. Bearing targets the logistics SaaS market, a $60B category with no agent-native solution.

III. The Solution

Stratum builds persistent agent infrastructure: append-only memory stores that survive session boundaries, structured inbox/outbox messaging that enables agent coordination, and self-healing monitoring that keeps fleets running without human intervention. This infrastructure is domain-agnostic.

On top of this infrastructure, Stratum builds domain-specialist agent products — each independently marketed, each solving a specific problem for a specific customer. The model is P&G or Unilever: one infrastructure layer powering many independent product brands, each competing on its own merits.
