Started in Bagdogra in 2018. We build managed websites and
custom software, and support the work ourselves.
We work with clear scopes,
direct engineering contact, and ongoing monthly support.
You talk directly with the founders who make decisions and write the code, without account manager layers.
Direct contact with engineers keeps the conversation and delivery aligned.
Hosting, updates, search indexing, and improvements stay with the same team that built the system.
The support plan is agreed before launch, keeping technical ownership clear.
Based in Bagdogra, Siliguri, we reply directly on WhatsApp and work with businesses across India.
WhatsApp, phone calls, and email keep communication simple.
