Custom AI Agent Development

Custom AI Agent Development Built Around Your Workflow

Bespoke agents built with Claude, GPT-4o, or open-source models, with custom tool-use, structured output, and multi-step reasoning designed around your specific workflow, not a generic template.

Why bespoke beats off-the-shelf

A generic AI tool wasn't built for your edge cases

Off-the-shelf AI tools are built for the average use case. A custom agent is built for yours: it uses your internal APIs, follows your business logic, respects your exceptions, and produces output in exactly the format your team already works in. That's the difference between a demo and something your team actually relies on.

We design across five layers: the model doing the reasoning, the tools it can call, the memory it draws on, the orchestration logic that decides what happens next, and the observability that tells you why it succeeded or failed. Most of the engineering value lives in the last three, which is exactly what off-the-shelf tools skip.

Model-agnostic

Claude, GPT-4o, Gemini, or open-weight

Tool-use

Calls your APIs, databases, and code

Structured

Output formatted for your systems

Production-grade

Built to survive real traffic, not a demo

What's included

From workflow audit to production agent

Workflow Discovery & Scoping

We document the actual steps of the process, including exceptions and edge cases, before writing any code.

Model Selection & Architecture

Choosing between Claude, GPT-4o, Gemini, or open-weight models based on latency, cost, and capability needs.

Custom Tool & API Integration

Well-defined tool functions for web search, database queries, external APIs, and code execution.

Structured Output & Reasoning Design

Multi-step decision logic and output formatted to plug directly into your existing systems.

Testing & Eval Framework

Structured logging and evaluation before launch, so you know the agent works before real users touch it.

Production Deployment & Support

Deployed into your infrastructure with 30 days of post-launch monitoring to catch real-world failure patterns.

SaaS: Sales Intelligence Agent

82%

reduction in time spent on lead research

We built a custom research agent for a B2B SaaS sales team that pulls company data, firmographics, recent news, and LinkedIn signals, then delivers a structured one-page brief per prospect in under 3 minutes. Previously an SDR spent 25 minutes per lead doing the same research manually.

FAQ

Common questions about custom AI agent development

An off-the-shelf AI tool responds to prompts: it produces text. A custom AI agent can take actions: call your specific APIs, query your databases, write and execute code, and chain multi-step decisions to complete a goal end-to-end. Because it's built around your workflow rather than a generic use case, it can use your internal tools, follow your business logic, and produce output in exactly the format your team needs.

We work across the major providers: Anthropic Claude, OpenAI GPT-4o, Google Gemini, and open-source models (Llama, Mistral) for on-premise or cost-sensitive deployments. Model choice is driven by the task, not preference: Claude for reasoning-heavy tasks, GPT-4o for multimodal input, and open-source models for high-volume pipelines where API cost matters.

A single-purpose agent, for example a report-generation agent connected to your analytics APIs, takes 4 to 6 weeks from scoping to deployment. We always start with a 2-week discovery sprint to define the agent's task scope, tool requirements, and success metrics, and ship a working proof-of-concept before building out the full production system.

We design for failure from the start: human-in-the-loop checkpoints for high-stakes actions, structured logging of every agent step so failures are diagnosable, and confidence thresholds below which the agent escalates rather than acts. Every build includes 30 days of post-deployment support so we can catch failure patterns in real traffic before they become habitual.
