AI Development & Automation Services
Pruning Labs is an AI agency, AI automation company, and applied AI lab based in Kolkata, India. We design, build, and deploy production AI systems, intelligent workflow automations, and custom full-stack software for fast-moving businesses. Founded by engineers from IIT Kharagpur and IIT Guwahati, our engagements focus on removing operational complexity and shipping robust, deterministic systems.
The method underneath all three is subtraction. Before we add software, we look for what can be removed: the step nobody needs, the service that exists because of a decision made two years ago, the dashboard nobody opens. What survives that pass gets built properly.
Production AI Systems
Applied AI lab and engineering agency shipping production AI systems: retrieval-augmented generation on pgvector, deterministic multi-agent supervisors, evaluation harnesses, and guardrails. Built in Kolkata, deployed for teams worldwide.
Intelligent Workflow Automation
We replace repetitive operational toil with idempotent, event-driven automation: durable workflows, system integrations, exception dashboards, and alerting your operators can trust. Software engineering studio based in Kolkata, working with teams worldwide.
Custom Software Engineering
AI-driven custom software development and engineering for teams that need sub-50ms responses, honest architecture, and code they can own. Next.js, Go, PostgreSQL and edge deployment, built in Kolkata by IIT alumni engineers.
How an engagement runs
- Discovery (1–2 weeks). We watch the real process, read the real code, and write down what is actually true. You get an architecture document and a scoped proposal whether or not you continue.
- First release (6–12 weeks). Fixed scope, written acceptance criteria, weekly demos against them. No open-ended hour-billing.
- Handover. Repository, infrastructure definitions, runbook, and working sessions with your team.
- Retainer (optional). Continued work only where there is continued work worth doing.
AI agency & automation questions
What is an AI agency?
An AI agency is an engineering firm that designs, builds, and deploys specialized artificial intelligence systems — including retrieval-augmented generation (RAG), autonomous AI agents, voice AI, and model integrations — tailored to a business's proprietary data, APIs, and operational workflows.
What does an AI automation agency do?
An AI automation agency designs and builds systems that replace manual, repetitive operational tasks with intelligent workflows. This includes connecting disparate business software, document parsing, voice calling agents, and automated exception queues that eliminate human busywork.
How is an AI lab different from a traditional software agency?
A traditional software agency builds standard web applications and CRUD interfaces. An AI lab like Pruning Labs conducts applied engineering on foundation models, vector retrieval, agentic workflows, and voice AI, maintaining its own production product line (Paithra, CA Folio, Medikle, Hireeing) alongside client systems.
Does Pruning Labs work with businesses in Kolkata?
Yes. Pruning Labs is headquartered in Thakurpukur, Kolkata and works with local companies across West Bengal in retail, manufacturing, logistics, and healthcare, as well as teams across India and globally.
AI-native products built in our lab
In addition to client systems, Pruning Labs engineers and operates its own suite of AI products:
