The problem

Your business runs on WhatsApp, Tally, and Excel.Most AI tools weren't built for that.

Three holes that quietly leak money every month — until something automates them.

Leads die after-hours

Half your WhatsApp messages and missed calls come outside 10–6. Your front desk is gone. Your team is sleeping. Your competitor's bot just replied in 2 seconds.

₹40K–₹3L / month lost — typical Indian SMB

Your team retypes the same data 4 times

WhatsApp → Tally → Excel → CRM → Email. Every customer touches 3 spreadsheets. Errors creep in. Founders end up reconciling at midnight.

10–40 FTE-hours / week — verified across n8n setups

Foreign AI tools don't speak your stack

ChatGPT can't post to Tally. Western voice agents stumble on Hinglish. Western chatbots don't know GSTR-2B. You're paying global tool prices for half a solution.

Wrong stack. Wrong language. Wrong invoice format.
