We are an AI agency and custom software development company based in Thakurpukur, Kolkata, India. Founded in 2026 by engineers from IIT Kharagpur and IIT Guwahati, we build production AI systems, intelligent workflow automation, and proprietary products including Paithra (AI voice calling platform), CA Folio, and Medikle.

Yes. Pruning Labs is headquartered in Thakurpukur, Kolkata (700104) and works with local businesses across West Bengal in retail, manufacturing, logistics, healthcare, and professional services, as well as international clients across India, the US, UK, and UAE.

A thirty-minute call, then a paid one-to-two-week discovery that ends with an architecture document and a scoped proposal you own either way, then a fixed-scope first release over six to twelve weeks with weekly demos against written acceptance criteria.

The founders and core engineers. The person in your architecture review call is the person shipping the pull request. There is no outsourced delivery layer, no account manager telephone game, and no junior bench being trained on your budget.

Entirely. Repository, infrastructure definitions, runbook, and an architecture document explaining the trade-offs. No licensed platform of ours embedded in your product, and no dependency on us to keep it running.

By constraining rather than hoping. Answers are grounded in retrieved passages with citations, action-triggering outputs are schema-validated, arithmetic and business rules stay in ordinary tested code, low-confidence cases route to a human, and an evaluation suite gates every prompt change in CI.
