The agentic AI shift
The global AI agent market is projected to grow from $7.6 billion in 2025 to over $182 billion by 2033. In India, businesses from real estate to e-commerce to healthcare are racing to deploy autonomous AI agents that qualify leads, answer customer queries, automate operations and unlock 24/7 productivity.
But most agencies still ship demo-grade chatbots that hallucinate in production. We don't. We build production-grade AI agents with proper evaluations, guardrails, observability, cost monitoring and human-in-the-loop fallbacks. The difference shows in week 4, when your agent is handling real customers without breaking.

FAQs
AI agent development is the process of building autonomous software systems that can perceive their environment, reason about goals, use tools (APIs, databases, browsers), and execute multi-step tasks with minimal human supervision. Unlike traditional chatbots that follow rigid scripts, AI agents adapt their behaviour based on context and feedback to achieve business outcomes.
AI agent development cost in India ranges from ₹40,000 for a single-task chatbot, ₹1,80,000 to ₹6,00,000 for a production-grade integrated agent, and ₹8,00,000+ for enterprise multi-agent systems. Final pricing depends on integrations, model choice, expected traffic, and accuracy requirements. We provide fixed INR quotes with GST invoice within 24 hours of your enquiry.
A simple RAG chatbot or workflow agent takes 2 to 4 weeks. A production agent with CRM and helpdesk integrations takes 5 to 10 weeks. Enterprise multi-agent systems take 12 to 20 weeks. We always ship a working prototype in the first 7 days so you can validate the use case before full investment.
A traditional chatbot follows pre-defined decision trees and intents. An AI agent uses a large language model to reason about its goal, decide which tools to call (search, database, API, calculator), execute multi-step plans, and self-correct when something fails. Agents are non-deterministic, tool-using, and goal-oriented, while chatbots are scripted and reactive.
We are model-agnostic. We use OpenAI GPT-5 for general reasoning and tool use, Anthropic Claude Sonnet 4.6 for long-context document analysis and coding, Google Gemini 2.5 for multimodal tasks, and open-source Llama or Mistral models when data privacy or cost requires on-premise deployment. We pick the right model per task, not per fashion.
Yes. We build voice agents in Hindi, English, Gujarati, Tamil, Telugu, Marathi and Bengali using ElevenLabs, Sarvam AI, and OpenAI's voice models. They handle inbound and outbound calls over Twilio or Exotel, integrate with your CRM, and are tuned for Indian accents and code-mixed conversation.
Our agents integrate with HubSpot, Zoho, Salesforce, Freshdesk, Zendesk, Intercom, Slack, Microsoft Teams, Google Workspace, Notion, Airtable, WhatsApp Business API, Razorpay, Shopify, WooCommerce, Odoo, Tally, custom databases (Postgres, MySQL, MongoDB), and any REST or GraphQL API.
We build evaluation datasets specific to your use case, run automated evals before every deployment, add guardrails using libraries like Guardrails AI or NeMo Guardrails, implement human-in-the-loop for high-stakes decisions, log every agent action for audit, and monitor token costs and latency in production. Quality is engineered, not hoped for.
Yes. After launch, we offer monthly retainers starting at ₹35,000 per month for prompt tuning, eval improvements, new tool integration, edge-case handling and model upgrades. Most clients stay on retainer because AI agents need continuous improvement as your business and the underlying models evolve.
Yes. We deploy on AWS, Google Cloud, Azure, Vercel, or your own VPC. For sensitive workloads we deploy fully on-premise using open-source models like Llama 3.3 or Mistral, with no data ever leaving your infrastructure. We also handle DPDP, SOC 2 and ISO 27001 compliance requirements.
