AI agents that actually reach production

We build agents that run complete processes inside your operation —not demos— together with the system around the model that makes them trustworthy: permissioned tools, independent verification, guardrails and traceability for every action.

  • A 7-layer method (the harness) applied from day one, not bolted on
  • Integrated with your current systems through APIs and MCP, without replacing them
  • On the cloud you choose or on your own infrastructure

Design principles

  • Every action with side effects is traced and auditable
  • No critical action without verification or human approval
  • Custom evals before going to production
  • Least privilege for every tool

The model is no longer the advantage

Everyone has access to the same models today. The difference between an agent that impresses in a demo and one that runs a real process is the engineering around it: which tools it can use and with what permissions, who checks its work, what it remembers, what it is forbidden to do and whether anyone can reconstruct what it did.

That is called harness engineering, and it is what we specialize in.

What we build

End-to-end process agents

An agent receives a request, queries the systems involved, runs the steps and delivers the result. It only escalates to a person when it should.

Fixed rules with no decisions? Automation fits better →
Multi-agent systems and orchestration

An orchestrator splits the work across specialized agents (research, execute, verify), with clear contracts between them.

IT operations agents

Alert triage, incident correlation, deployment preparation and assisted runbooks. Always with human approval for irreversible actions.

Agents over internal knowledge (permission-aware RAG)

They answer over your documents, policies and databases, respect the permissions of whoever asks and cite the source.

Document agents with judgment

They extract data, validate it against business rules and resolve ambiguity. They verify before recording anything.

Copilots for internal teams

Assistants that prepare, draft and propose. The person decides and approves.

The harness: 7 layers around the model

The model is the easy part. What makes an agent trustworthy is everything around it.

  1. 1. Orchestrated tools

    The model never touches a system directly: an intermediate layer validates, limits and logs every call.

  2. 2. Independent verification

    Whoever checks is not whoever acts. A verifier approves every action with side effects before it runs.

  3. 3. Context and memory

    The agent gets only what it needs, from permissioned sources, and forgets what it should forget.

  4. 4. Guardrails

    Behavioral, data, tool and operational limits, defined before the first prompt is written.

  5. 5. Observability

    Every step is traced: what it saw, what it decided, which tool it used and with what permission. Designed to catch drift before your users do.

  6. 6. Model routing

    Every task goes to the right model by cost, latency and data sensitivity, including private models.

  7. 7. Continuous feedback

    Production errors become test cases. The agent improves on evidence, not intuition.

Before building agents for others, we use them ourselves

What we offer is what we use every day.

Niveleads: agents in our sales operation

In Niveleads, our commercial platform, agents prospect, build campaigns, send automated emails and review how each lead engages. They also make AI voice calls, run technology watch, support growth and marketing, and read signals to give the team insights.

Agent-assisted engineering with independent QA

We build software with agents that write, test and review code, but we do not leave everything to AI. Deliveries go through an independent QA agent and verification standards defined by our team. Whoever builds is not whoever approves.

A website built for agents

nivelics.com is designed to be read by agents and LLMs as well: a dynamically generated llms.txt, schema.org structured data and content written with LLMs in mind.

Reference architectures

Illustrative scenarios of how we build. They do not describe clients or results.

Operations agent: from alert to deployment

An organization with many systems and an operations team flooded with alerts.

  1. Alert
  2. Triage agent
  3. Changes, logs and runbooks via MCP
  4. Verifier
  5. Execute and notify, or request approval
  6. Audit log

The agent correlates each alert with recent deployments and changes, queries logs and runbooks, classifies severity and proposes an action. Reversible actions pre-approved in the runbook, such as restarting a service, run once the verifier signs off, and the team is notified. For irreversible ones it prepares the plan and waits for human approval.

Harness: Read-only tools by default · verifier checks against the runbook · traces for every decision · evals built from past incidents

Multi-system orchestration of a business process

A process that crosses several systems and teams, with rework caused by inconsistent data.

  1. Request
  2. Orchestrator
  3. Integration and execution agents
  4. Verifier
  5. Close, or exception to a person

An orchestrator receives the request. An integration agent validates data across the ERP, the document system and the database. An execution agent records the changes, and an independent verifier confirms consistency before closing. Exceptions reach a person with all the context already assembled.

Frequently asked questions

A chatbot talks. An agent acts: it queries systems, makes bounded decisions and completes tasks. That is why it needs permissions, verification and traceability that a chatbot does not.

No. We build an integration layer (APIs or MCP servers) on top of what you already have, including legacy systems. The agent works through that layer, never directly.

We design so errors are detectable and contained: an independent verifier, evals before every change, human approval for irreversible actions, operational limits and rollback. Every production error becomes a test case.

You decide. It can be processed in your cloud (Amazon Bedrock or Azure OpenAI, with regional deployments in the region you choose, no global or cross-region inference, and without the provider using your data to train its models) or on your own infrastructure with open-weight models.

It depends on the process, the integrations and the level of autonomy. In discovery we define scope, architecture and cost against measurable success criteria.

Which process would you hand to an agent?

In discovery we pin down the process, the risks and the autonomy level before writing a line of code.
