Custom AI agents that handle complex tasks autonomously: integrated into your existing workflow and running 24/7.
An AI agent is a software system built on a large language model that carries out multi-step tasks on its own: reading inputs, deciding which tools to call, acting in other systems and handling errors without a person directing each step. Agents are used for customer service, research, data entry and operations work that follows a pattern but varies in detail.
GrossiWeb is a web design and digital marketing agency founded in 2006 and based in Atlanta, Georgia, serving Raleigh, Los Angeles and businesses nationwide. Its AI agent service designs, builds and deploys custom agents on Claude and OpenAI models, integrated with a client's existing tools and monitored in production, and is quoted after a scoping call.
AI agents are autonomous systems that can handle multi-step tasks without human intervention. We build them using Claude and OpenAI's APIs: with the prompt engineering, tool use, and error handling that production deployment requires.
Task definition, tool selection, workflow design, and failure mode planning before any code is written.
Agent build, API integrations, and connection to your existing tools and data sources.
Production deployment with logging, error alerting, and performance monitoring.

Define one task with a clear input, output and failure case, choose the tools the agent may call, and plan what happens when it is unsure before writing any code. GrossiWeb follows that order: agent design and architecture (task definition, tool selection, workflow design and failure-mode planning), then development and integration with the client's tools and data, then production deployment with logging, error alerting and performance monitoring.
The best agent is the one built for a task the business already does often and can describe precisely, such as triaging inbound inquiries, preparing quotes from a form, or researching prospects before a call. Generic assistants are useful for individuals; a business agent earns its cost by being connected to the CRM, inbox and calendar the team uses. GrossiWeb builds on Claude and OpenAI models and chooses per task.
GrossiWeb quotes each agent after a scoping call and does not publish a starting price, because the number of tools the agent calls, the systems it integrates with and the testing needed to trust it in production decide the work. Model usage fees are billed by the vendor to the client directly and are estimated from measured usage during testing.
GrossiWeb quotes per agent after scoping; the price follows the number of integrations and the testing required, and model usage is billed separately by the vendor. No flat figure is published. Simpler pattern-based tasks are often cheaper as workflow automation, and the automation and scale solution explains how to decide which is which.
The Claude and OpenAI APIs are the model platforms GrossiWeb builds on; n8n is the workflow platform it uses to connect agents to email, CRM and calendar tools; and the Model Context Protocol lets an agent act in other systems. The platform matters less than the task definition. Connections are described under LLM and MCP integrations and knowledge access under knowledge and data systems.
One built for a frequent, well-described task and connected to the tools the team already uses; that beats any general assistant for business work. GrossiWeb scopes the task first, often through AI strategy consulting, then builds and monitors the agent. Customer-facing agents for healthcare practices are scoped with their compliance requirements from the start.
AI & Automation work rarely stands alone. These are the services we most often pair with this one.
