    An AI agent is different from a chatbot in a specific, load-bearing way: a chatbot responds, an agent acts. Give an agent access to your CRM, your ticketing system, or your codebase, and it can look things up, take multi-step actions, and keep going until the task is actually done — not just produce a paragraph of text about what someone else should do next. That distinction is where most of the real business value sits, and it's also where most of the engineering risk sits.

    Single agent or multi-agent — and why it matters for cost

    A single-agent workflow handles one well-defined task with a fixed set of tools — a support-ticket resolution agent, an invoice-processing agent. It's the right starting point for most teams: faster to build, easier to evaluate, and easier to trust in production because there's one thing to get right. A multi-agent system splits a complex workflow across specialised agents that hand off to each other — a research agent, a writer agent, a verification agent — which is powerful for genuinely multi-stage work but multiplies the surface area for something to go wrong. We default to single-agent unless the workflow actually has distinct stages that benefit from different tools or prompting strategies.

    Why guardrails aren't optional

    An agent that can take actions is an agent that can take the wrong action, at scale, unattended. Every production agent we ship has input validation, output filtering, rate limiting, and audit logging built in from the first sprint — not added after an incident. For anything touching customer-facing decisions or financial data, we add human-in-the-loop checkpoints so the agent proposes and a person approves, until the failure modes are well enough understood to remove the checkpoint.

    Where agents sit in a wider AI build

    Agents are one shape of AI work, not the only one. Plenty of teams arrive asking for an agent and leave with something simpler that solves the same problem — a retrieval pipeline, a fine-tuned classifier, a well-scoped generative feature. As a custom AI development company we scope the whole surface before committing to an architecture: our generative AI development services cover model selection, RAG, and evaluation, and our LLM integration work covers the plumbing that any of it needs to reach production. If an agent genuinely is the right answer, we build the agent. If it isn't, we say so before you've paid for one.

    What we build

    What We Build

    Autonomous Task Agents

    Agents that plan multi-step workflows, select tools, execute actions, and iterate until the goal is reached — without human intervention at each step.

    Multi-Agent Orchestration

    Supervisor-worker agent architectures where specialised agents collaborate on complex tasks. Research, analysis, writing, and verification — each handled by the right agent.

    RAG Knowledge Pipelines

    Retrieval-Augmented Generation systems that ground your agent in your private data: documents, databases, APIs, and internal knowledge bases.

    Production-Safe Guardrails

    Input validation, output filtering, rate limiting, audit logging, and human-in-the-loop checkpoints to keep your agent operating safely in production.

    Tool & API Integration

    Custom tool functions connecting your agent to internal systems, third-party APIs, databases, and external services — fully typed and tested.

    FAQ

    Frequently Asked Questions

    An AI agent is an LLM-powered system that can plan, take actions, use tools, and complete multi-step tasks autonomously without step-by-step human instruction. Unlike a chatbot that only responds, an agent can browse the web, query databases, call APIs, write code, and orchestrate other agents to complete complex workflows.

    A focused single-agent workflow takes 4–8 weeks to build, test, and deploy. A multi-agent system with custom tooling and integrations typically takes 3–5 months. Timeline depends on the complexity of tools, the quality of your existing data, and the number of integrations required.

    We build with LangChain, LangGraph, CrewAI, and AutoGen depending on the use case. For production-grade agents we prefer LangGraph for its stateful, graph-based orchestration. We are model-agnostic — OpenAI GPT-5, Anthropic Claude, Llama 4, and Mistral are all part of our standard stack.

    Generative AI development services produce content — text, code, images, structured output — in response to a prompt. Agentic AI development services produce actions: the system plans, calls tools, and works through a multi-step task until it is finished. Most production systems use both, with a generative layer doing the reasoning and an agentic layer deciding what to do with it. We scope which layer your problem actually needs before proposing an architecture.

    Both. AI agent development is one service inside a wider custom AI development practice that also covers generative AI development, RAG pipelines, LLM integration, model fine-tuning, and ML engineering. Clients often start with a single agent and expand, or arrive asking for an agent and find a simpler generative or retrieval build solves the same problem for less. We are a US-registered company and scope the whole surface before recommending an architecture.
