About Stratum

Sean built Stratum because AI agents in production keep failing on the same problem — they forget. Every session, fresh context. No institutional memory. No record of what worked last week, which approach failed in December, or what the client mentioned in the last call. The tools built on top of these agents are only as durable as their underlying infrastructure.

The failure mode is not the model. The model is capable. The failure mode is the absence of memory — and the infrastructure decisions that made it acceptable.

The Insight

Domain specialists need domain-specific agents, not general-purpose chatbots. A research lab needs a research agent that knows its methodology, its prior findings, its in-progress papers. A logistics company needs a logistics agent that knows its carriers, its seasonal patterns, its cost structure. A legal team needs an agent that knows its regulatory footprint.

But each of those agents needs the same plumbing underneath: persistent memory, structured messaging, self-healing monitoring. The infrastructure layer is domain-agnostic. The product layer is domain-specific.

The Model

Stratum is a collection of domain-specialist AI agent products, independently marketed and operated, built on shared persistent agent infrastructure. Think P&G or Unilever — one infrastructure powering many independent brands, each competing on its own merits in its own market.

The corporate parent — Stratum — is not the product. The products are Probe, Hatch, Accrue, Memoir, Warden, Mandate, and Bearing. Each has its own identity, its own pricing, its own go-to-market strategy. The infrastructure beneath them is Stratum.

Where We Are

Seven verticals are in development. Probe — research intelligence for academic labs — is first to market, with a pilot underway and a first paying customer target of March 2026. Stratum is pre-revenue, building in public.

We are remote-first.
