Agentic AI Development

AI that plans the work, delegates it,
and gets it done without step-by-step instructions.

Agentic AI is what happens when you stop asking AI to handle individual tasks and start asking it to own entire workflows. Multiple specialized agents. An orchestration layer that coordinates them. A system that adapts when something unexpected happens. We design and build these systems for production.

 

How this is different from building a single AI agent

If you are looking to build an AI agent that handles one specific job — a support agent, a document processing agent, a knowledge retrieval agent — the AI Agent Development page covers that. Start there.

This page is for something more complex.

Agentic AI is what you build when a single agent can’t do the whole job. When the workflow has multiple stages. When different stages require different capabilities. When the system needs to figure out what to do next based on what it just found out. When the goal is too complex to pre-script into a linear flow.

In an agentic system, an orchestrator receives a goal and breaks it down into sub-tasks. Specialized agents handle each sub-task. They pass information to each other. The orchestrator monitors progress, handles failures, and adapts the plan if the situation changes. The result is a system that can execute complex, multi-step work autonomously in a way that no single agent can.

This is harder to build than a single agent. It requires more careful architecture, more rigorous testing, and more deliberate governance design. It is also the level of AI capability that delivers the biggest operational impact — when it is built right.

What agentic AI actually is

Three characteristics that set it apart.

An agentic system has three characteristics that distinguish it from a standard AI agent or a simple automation:

Goal-oriented. The system is given a goal or an outcome, not a step-by-step script. It determines the steps needed to achieve that goal based on what it discovers along the way.

Multi-component. Multiple specialized agents, tools, and data sources work together. An orchestrator coordinates them, routes outputs, handles failures, and manages the overall execution state.

Adaptive. When the system encounters something unexpected — an API returns an error, a retrieved document doesn’t answer the question, an intermediate result changes the direction of the task — it adapts rather than stopping or producing a wrong answer.

A customer support chatbot is not agentic. A workflow automation that follows a fixed script is not agentic. An AI system that receives a complex customer issue, retrieves the relevant account history, cross-references it with the product knowledge base, drafts a resolution, escalates only the elements requiring human judgment, and updates the CRM when complete — that is agentic.

The difference is not just technical. It is the difference between AI that handles individual tasks and AI that handles outcomes.

Where agentic AI fits in your AI journey

Usually the third step, not the starting point.

Most product teams arrive at agentic AI through a sequence of steps, not as a starting point.

The first step is usually a language model integration: a chatbot, a content generation feature, a search tool. The model answers questions and generates outputs. It works for well-defined, single-turn interactions. Its limitation is that it can’t act on what it produces.

The second step is typically RAG: connecting the model to your own data so it answers from your knowledge base rather than from general training. This is more useful and more accurate for your context. Its limitation is still that it responds — it doesn’t take actions or coordinate across multiple steps.

Agentic AI is the third step. The model can now plan, use tools, take actions, coordinate with other agents, and check its own work. It moves from answering to doing. From responding to executing.

Understanding where you are in this sequence matters before you consider agentic architecture. If you don’t yet have LLM integration in your product, start there. If you have LLM integration but your AI doesn’t connect to your own data, RAG is the right next step. If you have both and your AI is responding reliably but can’t handle complex, multi-step tasks on its own, agentic architecture is the right direction.

The AI Consulting Services page covers how to assess which step fits your current situation. This page is for teams who are ready for the third step.

What we design and build

Five kinds of agentic systems.

Multi-Agent Orchestration Systems

Multi-Agent Orchestration Systems

The foundational architecture of agentic AI. An orchestrator receives a goal or trigger, decomposes it into sub-tasks, delegates each to a specialized agent, collects and integrates the outputs, and manages the overall execution flow. We design the orchestration logic, define the agent roles and boundaries, and build the communication layer between them. The result is a system where complexity is handled by the architecture, not by any single component.

End-to-End Agentic Workflow Automation

End-to-End Agentic Workflow Automation

Replacing multi-step workflows that currently require human coordination between tools, systems, and decision points. We map the existing workflow, identify where AI can handle each stage, design the transitions and handoffs between stages, and build a system that runs the whole workflow with human involvement only where the stakes or the ambiguity require it. Examples: multi-stage document intake and processing, complex customer onboarding across multiple systems, research-to-report pipelines that currently involve multiple manual steps.

Goal-Oriented Task Execution Systems

Goal-Oriented Task Execution Systems

Systems where the input is a high-level goal and the AI determines how to achieve it. The system plans, executes, checks its own work, and adapts when intermediate results change the path forward. These systems use plan-then-execute architectures with self-evaluation loops that catch and correct errors before they propagate. Useful for research pipelines, analysis and reporting workflows, and any task where the path to the outcome is not fully predictable upfront.

Agentic Features Inside SaaS Products

Embedding agentic capability directly into the product you sell. A user triggers a complex action — “prepare a full report on this client,” “analyze this property portfolio and flag risks,” “review and summarize all open issues” — and the system handles it autonomously in the background, involving the user only at defined checkpoints or for final review. This is where GTC’s product engineering background matters most: the agentic system has to fit cleanly into the product architecture, the user experience, and the data model.

Agentic Data and Research Pipelines

Agentic Data and Research Pipelines

Multi-agent systems that automate data gathering, processing, synthesis, and delivery. One agent retrieves, another validates, another transforms, another synthesizes, another formats and routes. Useful for competitive intelligence pipelines, multi-source research summarization, automated reporting workflows, and any process that currently involves pulling information from multiple sources and producing a consolidated output.

Agentic patterns we design

The architecture follows the workflow.

Not every agentic system is structured the same way. The architecture depends on the workflow, the complexity, the required reliability, and where human oversight is needed. Common patterns we work with:

 

Orchestrator and worker agents

A central orchestrator LLM manages overall execution and delegates specific tasks to lighter-weight specialized agents. The orchestrator carries the full context; the workers are optimized for their specific functions.

Plan-then-execute

The system generates a structured plan before executing any steps. Each step is validated before the next begins. If a step fails or produces an unexpected result, the plan is revised before continuing.

Parallel execution

Multiple agents work simultaneously on independent parts of a task. The orchestrator collects and integrates outputs. Used when tasks are decomposable into independent sub-tasks and speed matters.

Human-in-the-loop checkpoints

Defined points in the workflow where the system pauses, presents its work to a human, and waits for approval before continuing. Used where the consequence of an error is high or where a decision requires human judgment.

Retrieval-then-act

The system retrieves relevant information before taking any action, grounding its decisions in current, accurate data rather than model memory. Essential for agentic systems that touch production systems and need to base decisions on real-world state.

How we build agentic systems

Seven steps, anchored by goal definition and orchestration design.

Step 1: Define the goal and the scope boundary

What outcome should the system achieve? What is the starting trigger? What are the boundaries of what the system is allowed to do autonomously? Where are the human checkpoints? These questions are answered before any architecture is designed. Agentic systems without clear boundaries and governance design create unpredictable behavior in production.

Step 2: Map the workflow and define agent roles

We decompose the target workflow into stages. For each stage, we define: what information is needed, what decision or action needs to happen, which agent or tool handles it, what the output looks like, and how it feeds the next stage. This gives us a complete picture of the system before we build any component.

Step 3: Design the orchestration architecture

We design the orchestration layer: which model acts as orchestrator, how the orchestrator communicates with worker agents, how execution state is maintained, how the system recovers from failures, and how human escalation is triggered. This is the most critical engineering layer in an agentic system and the one most often underspecified in early builds.

Step 4: Build and test each component

We build each agent and integration point separately, testing with representative inputs before integrating them into the full system. Individual component reliability matters because failures compound in multi-agent pipelines. A component that is unreliable at 5% of inputs produces unreliable end-to-end results at a much higher rate.

Step 5: Integrate and test end to end

We test the full system against realistic inputs, including adversarial cases and failure scenarios. We probe the points where agent outputs feed into subsequent agents. We test the human escalation paths. We run cost and latency benchmarks under simulated load. The goal is a system that is reliable enough for production, not just impressive in a controlled demo.

Step 6: Deploy with observability and governance

We deploy with execution tracing, audit logs, cost monitoring, and performance dashboards. Every decision the orchestrator makes is traceable. Every agent action is logged. Human escalation rates, task success rates, and costs are monitored from day one. These are not optional additions: they are how you build confidence in a complex autonomous system over time.

Step 7: Tune and expand post-launch

Agentic systems improve substantially with production data. We use execution traces and outcome data to identify failure points, improve orchestration logic, tune prompts, and refine agent scope. We also help you identify the next workflows to bring into the system as the first deployment proves its value.

Technology we build with

Orchestration frameworks, sized to the system.

Orchestration frameworks

Lang Graph (for stateful, complex multi-step orchestration with fine-grained control), CrewAI (for role-based multi-agent collaboration), AutoGen (for agent conversation and self-refinement loops), and LlamaIndex (for retrieval-augmented multi-agent pipelines). Framework choice is matched to the complexity and control requirements of the specific system.

Language model providers

OpenAI (GPT-4 and o-series reasoning models), Anthropic Claude, Google Gemini. For agentic systems, model selection matters at each layer: orchestrators benefit from strong reasoning and instruction-following; worker agents can use lighter, faster models tuned for their specific task.

Memory and state management

Persistent execution state, shared context between agents, vector databases (Pinecone, pgvector, Weaviate) for retrieval, and session memory management for systems that operate over long time horizons.

Tool integration layer

REST APIs, webhooks, databases, CRM and ERP systems, document stores, communication platforms, and any other external system the agents need to interact with. Tool catalogs with explicit permissions per agent role, so no agent can access systems outside its defined scope.

Evaluation and observability

Lang Smith and Langfuse for execution tracing and LLM call monitoring, custom dashboards for task success rates and escalation tracking, and cost monitoring at the workflow and agent level.

Application and product integration

React, Angular, Node, Java, React Native, iOS, and Android. Agentic systems built to integrate cleanly with existing product architectures, not as external services bolted on to the product.

Cloud infrastructure

AWS, Google Cloud, and Azure. Deployment architecture designed for the reliability and scale requirements of autonomous systems in production.

What we don't build

The clearer the goal, the better we build it.

We build agentic systems using existing AI providers and orchestration frameworks. We don’t train custom foundation models, build proprietary agent platforms, or provide ongoing ML operations for production model management.

We also don’t build systems where the level of autonomy required exceeds what can be safely governed without enterprise-grade AI governance infrastructure. If your use case requires that level of oversight, we’ll tell you and help you understand what additional infrastructure is needed.

We are product engineers who design and build well-engineered agentic systems. The more clearly you can define the goal, the workflow, and the governance requirements, the better we can build it.

"We needed AI search built into our platform without rebuilding the whole product. GTC designed the integration cleanly, it shipped on time, and it actually improved how users found things. That was the measure that mattered."

"They were honest from the start about what AI would and wouldn't solve for our specific product. That scoped the project correctly from day one. The integration worked in production on the first try."

FAQ

Questions teams ask about agentic systems.

An AI agent handles a specific, well-defined task with clear inputs and outputs. An agentic AI system handles something more complex: a goal that requires multiple steps, multiple information sources, multiple decisions, and often multiple specialized components working together. The system itself determines how to achieve the goal, adapts when it encounters unexpected situations, and coordinates the work across its components. The key distinction is that an agent executes a task; an agentic system pursues an outcome. If you need the first thing, the AI Agent Development page is the right starting point. If you need AI to handle a complex multi-step workflow end to end, this page covers that.

A few clear signals: the workflow has multiple distinct stages that require different capabilities; an intermediate result in one stage determines what happens next and that determination can’t be pre-scripted; information from multiple separate sources needs to be gathered, integrated, and acted on as part of the same task; or the goal you’re giving the AI is high-level enough that the steps to achieve it are not fully predictable in advance. If the task is well-defined, repeatable, and involves one clear set of inputs and outputs, a single agent is probably the right tool. If the task is complex, multi-stage, and involves judgment about how to proceed at multiple points, agentic architecture is the right approach.

The orchestrator is typically a capable LLM with access to a defined set of tools and worker agents. It receives the goal or trigger, generates a plan for how to achieve it, delegates specific sub-tasks to appropriate agents or tools, collects and integrates the outputs, evaluates whether the result so far is on track, and determines what happens next. The orchestrator maintains the overall execution state across the full workflow. The complexity of the orchestration layer varies depending on how much planning flexibility the system needs: some workflows can use a structured plan-then-execute approach, others need a more dynamic loop where the orchestrator re-evaluates after each step.

Through deliberate governance design at the architecture level, not as an afterthought. We define explicit decision boundaries at the start of every agentic system design: what the system can do without human approval, what requires a human checkpoint before continuing, and what always escalates to a human. We implement confidence thresholds so the system pauses and asks when it is uncertain. We design blast radius limits so that a single error doesn’t propagate uncontrolled through the workflow. And we build full audit trails so that every decision the orchestrator makes is reviewable. Control is a design requirement, not a feature we add later.

We design failure handling into every agentic system before we build it. Each component has defined failure responses: retry logic for transient failures, fallback behaviors for persistent failures, and escalation paths for failures that require human attention. The orchestration layer is designed to catch failures and route them appropriately rather than silently producing wrong outputs or stopping the workflow in an unhandled state. This is one of the most important differences between a production agentic system and a prototype: the prototype works when everything goes right; the production system is designed for what happens when things go wrong.

We test components individually first, with representative real-world inputs, before integrating them. Then we test the full system end to end against a diverse set of realistic scenarios including adversarial cases, failure cases, and edge cases. We run specific tests on the orchestration logic: what happens when an agent returns an unexpected output format, when an API call fails, when the confidence threshold is not met. We also run cost and latency benchmarks at simulated scale. The goal is to understand the system’s behavior across a wide range of situations, not just the expected cases.

More than a single agent, and the timeline is more variable. A focused agentic system for a well-defined workflow typically runs six to twelve weeks from scoping to production deployment. More complex multi-agent systems with many integration points and governance requirements take longer. The most significant variables are how well the workflow is currently understood and documented, how many external systems need to be integrated, and how much data preparation is needed before the agents can function reliably. We scope specifically before starting.

Yes, this is possible and sometimes the right approach. We assess your existing agents, understand their inputs, outputs, and behaviors, and design an orchestration architecture that coordinates them into a coherent workflow. The main consideration is whether the existing agents are well-documented and reliable enough to serve as components in a more complex system. If there are reliability or behavior issues in the existing components, those need to be addressed before they become part of a larger agentic pipeline where errors can propagate.

Through clean, well-defined integration layers. Each external system the agentic pipeline touches is connected through an API or data connector that we design and build. We create a tool catalog for the orchestrator that defines exactly what actions each agent can perform on each external system, with appropriate permissions and access controls. We also design the data flow: how information is retrieved, how it is passed between agents, and how outputs are written back to the relevant systems. The goal is a system that fits cleanly into your existing infrastructure, not one that requires rebuilding it.

You do. Full architecture documentation, all source code, all prompt configurations, all integration logic. The system runs on your infrastructure or your choice of cloud provider. No proprietary platform, no vendor lock-in, no dependency on us to keep it running. We design with portability in mind: the orchestration framework choice and the model provider integration are both architected to be swappable without requiring a full rebuild.

Memory in agentic systems needs careful scoping. Too little memory and the system loses context across steps, producing disconnected or repetitive outputs. Too much unstructured memory and the system accumulates noise, which degrades decision quality over time and introduces unpredictability. We design memory with explicit scope: what the orchestrator retains across the full workflow, what individual agents retain within their task, and what gets cleared after each session. Retrieval-based memory (pulling relevant context from a vector store at the right moment) is often preferable to accumulating everything in a long context window, because it keeps the model’s active context focused and current. We test memory behavior as a specific system property, not as a side effect of the design.

Less than most teams expect, but a few things matter. You need someone who understands the workflows being automated well enough to define clear inputs, outputs, and decision rules for each stage. That person doesn’t need to be a developer, but they need to be available during the design and testing phases. You need technical access: APIs or data connections to the systems the agents will interact with. And you need a clear owner for the agentic system post-launch, someone responsible for monitoring the system’s behavior and making decisions when it surfaces edge cases. What you don’t need is a full internal AI team. That’s why you’re working with us.

Yes, with appropriate design constraints. In healthcare, every patient-affecting decision needs a defined human oversight path, data handling must meet HIPAA requirements, and audit trails are not optional. In financial services, consequential actions need approval workflows and full decision traceability. Agentic systems in these industries are designed with tighter autonomy boundaries than in lower-stakes environments: the system handles the information gathering and preparation stages, humans retain approval authority for consequential outputs. This is achievable and we’ve built in regulated contexts before. What we don’t provide is formal AI governance certification or enterprise compliance auditing. If those are required, we design for them and flag what additional infrastructure you’ll need.
