Custom AI Agent Development Services

A focused single-agent system handling a well-defined workflow — document extraction, email triage, API orchestration — typically reaches a production-ready v1 in 6 to 10 weeks. That includes scoping, architecture, tool integration, testing against real data, and a hardening pass. Multi-agent systems with complex orchestration run 12 to 20 weeks depending on the number of tools, the reliability requirements of each integration, and how much of the surrounding data pipeline we need to build or stabilize first.

We're framework-agnostic and choose based on your requirements. LangGraph works well for stateful, graph-based workflows where you need fine control over execution paths. AutoGen and CrewAI suit multi-agent collaboration scenarios. For high-throughput or latency-sensitive systems we often build a lightweight custom orchestration layer that gives you fewer abstractions to debug. We'll recommend a framework after scoping your use case, not before.

We design for failure from the start. That means maximum iteration limits on loops, structured retry logic with exponential backoff, confidence thresholds that trigger human review, and dead-letter queues for tasks the agent can't resolve. Every agent run produces a structured trace you can inspect. For high-stakes workflows we build explicit human-in-the-loop checkpoints where an agent must receive approval before taking an irreversible action.

Yes, and that integration work is usually where the real engineering effort lives. We build typed tool schemas for each external system, handle auth flows (OAuth, API keys, service accounts), manage rate limits and pagination, and write the data normalization logic so agents receive clean, structured inputs. We've integrated agents with Salesforce, HubSpot, SAP, PostgreSQL, REST and GraphQL APIs, and custom internal platforms.

Engagements typically range from $40,000 to $150,000 depending on scope — number of agents, complexity of tool integrations, whether we're building supporting data infrastructure, and team size. We offer a paid discovery and architecture sprint (usually 2 to 3 weeks) that produces a detailed technical spec and fixed-price estimate before you commit to full development. Dedicated team engagements for ongoing agent development start at three engineers.
