AI Product & MVP Development in Kolkata
The best AI Product & MVP Development in Kolkata, at the best available price.
A real, production-grade build you can put in front of users or investors. Frontend, backend, mobile, the agentic AI underneath, and the cloud or private infrastructure it runs on, as one engagement rather than four vendors.
Kolkata is the commercial centre of eastern India, with IT services concentrated in Salt Lake Sector V and New Town, and a business community long rooted in banking, microfinance, tea, jute, FMCG distribution and trading. Many established firms here are family or promoter run and adopt technology cautiously, often through someone they already trust, while lenders and microfinance institutions face the same RBI scrutiny as any bank in Mumbai.
Founders in Kolkata often build for sectors the city knows well: lending, distribution, education and logistics across eastern India. The build ships a production version suited to that market, including low-bandwidth use and regional language content where the customers need it.
What you get
- Full-stack build on Next.js, Node or Python, with a database and API design that survives past the MVP
- AI where it earns its place: LLM features, retrieval over your own documents, agent flows that call real tools, voice
- Auth, payments, analytics and an admin surface, not a demo that breaks on the second user
- Deployment across AWS, GCP or Azure, or private and on-premise hosting where the data demands it
- Clean, documented code on your own infrastructure, written to make us replaceable on purpose
Final pricing depends on scope, features and complexity, so we settle it on a call before any work starts.
Invoiced in INR, with GST as applicable.

Who builds here
On-Premise LLM Deployment
Kolkata's lenders and microfinance institutions hold sensitive borrower data, often collected in regional languages, and sit under RBI outsourcing rules. Keeping a model inside their own environment is usually the only way an AI project gets past the risk committee.
What Kolkata companies build with us
Get it built at $0.
That is not a discount. It is when you pay. The work is split into checkpoints with acceptance criteria written down before anything starts, and each checkpoint is invoiced only after you have seen it and accepted it. No deposit.
- $0 to start
- You hold every dollar until a checkpoint is delivered and you accept it. No approval, no invoice.
- Fixed cost, unlimited features
- Or hire the team outright: one fixed monthly cost, unlimited feature development, any stack.
- The engineer takes your call
- The person on your first call is the one who architects and writes it. No account managers, no bench time.
A US agency quotes $50,000 to $150,000 for the same build and asks for 40 to 50% of it before a line is written. Account managers, project managers, sales commission and bench time. None of it appears in your product.
Three stages, nothing hidden.
Twenty-minute call
You talk to the engineer who will build it, not a sales rep. We scope the problem and you get told plainly if this is the wrong fit.
Fixed proposal in 48 hours
Fixed price, fixed timeline, defined deliverables, in writing. No hourly billing surprises and no open-ended scope.
Weekly demos until it ships
Working software every week, direct access over Slack or WhatsApp, and documentation handed over at the end.
What actually applies here.
Regulation and data
Under the DPDP Act 2023 and the Digital Personal Data Protection Rules notified in November 2025, most obligations on data fiduciaries, including notice, consent, breach notification and data principal rights, are scheduled to take effect in May 2027, and the government has said it may shorten that window. For Kolkata's lenders, including microfinance institutions, the RBI Master Direction on Outsourcing of Information Technology Services and the 2023 Master Direction on IT governance, risk and controls set how a technology vendor may access and process borrower data, and digital lending is covered by the RBI's Digital Lending Directions. West Bengal promotes technology through projects such as the Bengal Silicon Valley Tech Hub and the fintech hub in New Town, which are infrastructure and incentive schemes rather than compliance rules.
Contracting and payment
Simple domestic contracting. Invoices in INR with GST as applicable, under a standard services agreement. No cross-border payment friction, no forex conversion cost, and no time spent on paperwork for an overseas supplier.
Working hours
Same time zone. I work from India on IST, so calls, reviews and replies all happen inside your normal working day.
Can an AI system work with documents in Bengali?
Yes, with care. Current open models handle Bengali text reasonably well for reading and summarising, but quality varies by task, so every project starts with a test set of your own documents and the results are measured before anything goes live.
Do you work with microfinance institutions and NBFCs?
Yes. Work is done under the institution's vendor and outsourcing process, with named, limited access, and where borrower data cannot leave its environment the model is deployed inside it, with every request logged for the institution's auditors.
Is three days realistic?
For a working, demoable version of a core idea, yes, and that is what the three-day build is. A full production system with billing, admin and hardening takes weeks, not days. We will tell you which one your situation actually needs.
Do we own the code?
Entirely. It ships into your repository on your own cloud accounts, documented so your team or your next hire can pick it up without us.
Can you also host the AI model privately?
Yes, and as part of the same engagement. If compliance means inference cannot leave your network, the serving layer and the application are built together rather than handed between vendors.
MVP Development
A working MVP in as little as 3 days, from $1,000. Production-grade, not a throwaway prototype.
