AI Agent Development Built for Real Work, Not Demos

LangGraph State Machines, Claude and GPT-4o Tool Use, Production Discipline

Work with senior agent engineers who have shipped autonomous agents to production across sales, customer service, research, code review, and internal operations. From a single-task LangGraph agent with Claude 3.5 Sonnet to multi-agent CrewAI systems with MCP tools, vector memory, eval suites, and human approval workflows, we build agents that pass an eval gate every sprint and stay safe in production.

How Much Does AI Agent Development Cost?

Honest USD Rate Bands From an Indian Senior Team

Fixed-scope agent MVPs we ship come in between $25K and $60K. Production agent platforms with multi-tool calling, vector memory, eval, and observability fall between $80K and $250K. Enterprise multi-agent systems with audit, role based access, and human approval workflows start at $300K. Prefer a senior agent engineer on your team instead? From $2,000 per month, first week on us.

What We Build

What can we build with AI agents?

Eight categories of AI agent development work, from a single LangGraph agent owning one task to multi-agent CrewAI crews coordinating across systems.

Reference Architecture

Which architecture do we use for AI agent development?

Six layers we wire together on greenfield AI agent development projects. Each layer is observable, testable, and bounded by guardrails.

Agent Loop

LangGraph state machine with ReAct or plan and execute pattern. Typed tool selection, deterministic recovery on failure, no hidden control flow.

Tools

Function calling with strict JSON schemas, Anthropic MCP servers, OpenAPI tools, Browser Use and Playwright actions. Allow lists on every external call.

Memory

Short-term working memory in state, long-term in Mem0 or Letta, semantic recall over Pinecone, Qdrant, Weaviate, or pgvector. Memory hierarchies you can audit.

Guardrails

Hard cost ceilings, rate limits, recipient and URL allow lists, output validators, fallback paths on tool failure. The agent cannot exit the rails you set.

Observability

LangSmith and AgentOps traces on every step, Helicone and Langfuse for spend, Arize for retrieval drift. Eval suite runs on every PR with Ragas and DeepEval.

Human in Loop

Approval checkpoints on high-impact actions via Slack and inbox. Full audit log of every tool call. Multi-agent coordination with explicit handoffs.

Every layer documented in your repository on day one
