AI Agent Development

AI agents that do the work, not just the chat

We design and build AI agents that call tools, query your systems, and complete multi-step tasks inside your product — engineered with the guardrails and oversight that make an autonomous system safe to run in production.

Why build an AI agent

A chatbot answers questions. An agent takes the next step — checking a status, updating a record, triggering a workflow — inside the systems you already run. That difference is what actually saves your team time.

Automates Real Work

Not a demo — an agent wired into your CRM, support desk, or internal tools that completes the task, not just describes it.

Stays Inside Guardrails

Every tool call is scoped to what the agent is allowed to do, with human approval on the actions that warrant it.

Built on Your Stack

Integrated with the APIs, databases, and services you already run, instead of asking you to migrate to a new platform.

Measured Before It Ships

Evaluated against real scenarios and edge cases before going live, and monitored once it is.

What we deliver

01

Agent Scoping & Architecture

We define what the agent is allowed to do, which tools it can call, and where a human needs to stay in the loop, before any code is written.

02

Tool & Workflow Development

Function-calling tools, multi-step workflows, and integrations with the systems the agent needs to act on — your CRM, database, or internal APIs.

03

Evaluation & Guardrails

Test suites built from real and adversarial scenarios, plus the permission scoping and approval steps that keep the agent inside its lane.

04

Deployment & Monitoring

A production deployment with logging and observability, so you can see what the agent did and why, not just that it ran.

Process

  1. 01

    Define

    Scope the tasks worth automating, the systems the agent needs to touch, and the guardrails that keep it safe to run.

  2. 02

    Build

    Develop the agent's tools, reasoning flow, and integrations, testing against real scenarios as we go.

  3. 03

    Ship

    Deploy to production with monitoring in place, then iterate on the scenarios the agent actually meets in the wild.

How we build agents

An agent that can take action needs more engineering discipline than one that only talks. These are the parts we do not skip.

Guardrails & Permission Scoping

Every tool call is scoped to a defined set of actions — an agent that manages your calendar cannot also touch your billing system.

Human Oversight Where It Matters

Reversible, low-stakes actions run autonomously; anything consequential routes to a person before it executes.

Evaluated Before It Ships

Agents are tested against real and adversarial scenarios — including the ones designed to make them fail — before going live.

Observability in Production

Every decision and tool call is logged, so when something goes wrong you can see why, not just that it did.

Faqs

Common questions about AI agent development

A chatbot answers questions in a conversation. An agent takes action inside your systems — calling APIs, updating records, and completing multi-step tasks — whether or not there is a chat interface in front of it. If you need a conversational interface specifically, that is a separate, narrower engagement.

AI-Assisted MVPs with Claude is us using AI internally to build your product faster. AI Agent Development is us building AI capability into your product — an agent your users or your team interact with after launch. The two are often combined, but they are not the same service.

Whichever fits the task and your constraints — Anthropic's Claude and OpenAI's models most often, integrated through provider-agnostic tooling so you are not locked into a single vendor. We choose based on the job, not a fixed stack.

Permission scoping on every tool it can call, human approval on consequential actions, and a test suite built from adversarial scenarios before launch. An agent's capabilities are a design decision, not an accident of what the model happens to be capable of.

Yes — that is most of the engineering work. We integrate with the APIs, databases, and internal tools you already run rather than asking you to adopt a new platform around the agent.

Yes. You own the codebase, the agent configuration, and the deployment. Everything is documented and handed over runnable by your own team.
