The Agent Cloud

The cloud platform for autonomous AI agents.

You bring the agents. Hexel runs them — orchestration, compute, tools, data, and governance in one vertically integrated platform. Ship from staging to production without building the infrastructure underneath.

Platform architecture

One vertically integrated stack — not six tools stitched together.

Every layer was designed together from day one. No latency tax, no credential sprawl. Select a layer to see what it does.

Layer 01

Orchestration

LLM-driven planning turns a goal into a DAG of agent steps, then the workflow executor runs it with structured handoffs and a shared fact bus.

Inside the runtime

Planning, control, visibility, and spend — built into the platform.

Production agent workloads need more than a model call. Hexel handles the full lifecycle with governance and observability at every step.

Orchestration

Planning runtime

LLM planning decomposes a goal into a DAG, then routes each step to the right agent with structured handoffs.

Task decomposition

  1. Decompose goal running
  2. Assign research agent
  3. Assign reason agent
  4. Assign action agent

Governance

Approval workflow

Policy engine returns ALLOW, DENY, or REQUIRE_APPROVAL — with a human review queue in the execution loop.

Tool Gateway

Governed access to the systems where work happens.

Agents discover, authenticate, and execute tools through one boundary layer — with OAuth, encrypted credentials, rate limiting, and a full audit trail on every call.
