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.
