Marsen Technologies (MarsenTech) is an AI automation and growth agency in Siliguri, West Bengal, India, founded by Debashi Majumder and Aranyak Sengupta. We fix the gaps where small businesses lose customers: missed calls, slow WhatsApp replies, leads that go cold and enquiries copied into Excel by hand. We set up instant WhatsApp and website replies, missed-call handling and appointment booking for clinics, automated lead follow-up and enquiry-to-CRM automation, built on n8n with the WhatsApp Business Platform and CRMs such as Zoho, HubSpot and Twenty. We also improve SEO and AI search visibility, and build websites and content for brands. Published fixed prices (India, excluding GST): AI receptionist for clinics from ₹39,999 + ₹4,999/month; enquiry-to-CRM automation from ₹39,999; WhatsApp lead follow-up sprint ₹34,999. International: Zapier or Make to n8n migration $450 per workflow; self-hosted n8n setup $499. Every project has a written scope, tests before launch and a handover. Our tested n8n labs and guides are public on marsentech.com.
