Kolkata, West Bengal

IT & Software Services in Kolkata

A Pune-based technology partner for startups, small businesses and MSMEs in Kolkata and across East India.

Kolkata is a city that combines an old trading economy with an IT belt at Sector V. We build software for the businesses behind that — banking, finance and insurance; IT and software services; and transport, fleet and logistics — from websites and mobile apps to CRM, ERP, billing systems and AI automation. We work out of Pune and deliver to Kolkata remotely, with fixed weekly check-ins and travel when a phase genuinely needs people in one room.

Frequently asked questions

Do you have an office in Kolkata?

No. Our only office is in Pune and we would rather say so than list a virtual address. We work out of Pune and deliver to Kolkata remotely, with fixed weekly check-ins and travel when a phase genuinely needs people in one room.

What does a small business in Kolkata usually start with?

Usually a website that brings enquiries, or billing and stock software that ends the spreadsheet problem. Both are small enough to judge us on before committing to anything larger.

Do you work with startups as well as established businesses?

Both. A startup usually needs an MVP shipped fast and cheaply enough to change direction; an established business usually needs its existing process made faster without breaking. The engagement model differs, the honesty about scope does not.

Can you support the software after it is built?

Yes, under an annual maintenance agreement with a defined response time. You can also take the code to any other developer — nothing about the way we build creates lock-in.
