Decipher Consultancy Services builds custom AI, RAG chatbots, ML models, AI agents and enterprise automation for Kolkata-based teams across Sector V Salt Lake, New Town Rajarhat DLF IT parks, Park Street, EM Bypass and the Kharagpur research corridor. Honest positioning first. We do not run a Kolkata office. Our engineers sit in Gurugram (Sushant Lok III, Sector 57) and Palwal in Haryana. Delivery is remote-first on the same IST clock, and we fly to Kolkata for kickoff, security reviews and quarterly business reviews when the engagement calls for it. Deep experience with BFSI back-office operations, IT-BPO, hospital HMIS, tea and jute analytics and IIT KGP / IIM Cal alumni startups. 12+ years operating, 500+ systems shipped, ISO 9001:2015 certified.
A lot of AI agencies list a Kolkata address that turns out to be a coworking day pass in Sector V or a business-centre plate on Park Street they walked into once. We chose not to. Our engineers actually sit in Gurugram and Palwal in Haryana, and that is what we tell you. What matters is whether the delivery works, and here is how it works for Kolkata buyers.
Discovery calls happen on Zoom, Google Meet or Teams, typically a 15-minute intro followed by a working session with an engineering lead. Once we agree scope, engineering runs from Haryana on IST, so there is no lag between your team in Salt Lake or New Town and ours. Standups are live, Slack replies land in minutes, and a hotfix pushed at 8 PM still gets a real review that night. Same setup that most Kolkata IT-BPO majors already run internally with their own Bengaluru or Pune delivery centres.
On-site visits to Kolkata happen 2 to 3 times per engagement on average. Kickoff and architecture whiteboarding is usually the first trip, often at your Sector V Salt Lake, DLF Rajarhat or Park Street office. A security review or RBI compliance walkthrough is usually the next. Quarterly review visits come with any managed operations retainer. Travel is baked into the SOW, so you never see a surprise line item for a flight to CCU.
For regulated Kolkata clients (banks, NBFCs, hospitals), we can deploy on your VPC, on-prem hardware or India-region cloud tenancy. Data does not need to leave your controlled environment. Consent trails, audit logs and DPDP-aligned processing records are part of the standard delivery.
