Live
You can see it land
Most vendors sell you one channel and hand the rest to someone else. Here every channel shares one customer profile, one opt-out list and one bill — and every event is logged, queryable and pushed to your webhook within seconds.

Messaging
Three channels, one conversation
An unsubscribe from SMS also stops the WhatsApp broadcast. That only works when the channels share a database instead of a monthly CSV.
The official API, not a modded phone
Verified business account, approved templates, broadcast to segments, and a shared inbox so replies do not land on one salesperson's personal phone.

Voice
Every kind of call software, on one switch

Why it matters
A caller who waits ninety seconds hangs up and calls a competitor. Callback-in-queue, skills routing and after-hours overflow are the difference between an abandoned call and a booked job — and none of them need more agents.
Commerce
The counter and the storefront, reading the same stock number
A sale in the shop should reduce what the website can sell, and a customer who bought yesterday should land in tomorrow's campaign without anyone exporting a spreadsheet.
Point of sale
A till that keeps selling when the line drops
Retail and F&B modes, multi-outlet stock and transfers, every payment method Indians actually use, and e-Invoice submission to the GST portal from the counter.

E-commerce
A store that loads fast and gets found
Server-rendered storefronts with a Core Web Vitals budget enforced in CI, local payment gateways and courier integration, and technical SEO done during the build rather than bolted on after traffic fails to arrive.

E-commerce solutions →Who we run for
Different industries, same three problems
Reaching people, answering them, and getting paid. What changes is the compliance paperwork and the peak hour.
Banking & collections
Predictive dialling, call recording and OTP delivery inside the audit trail your compliance team expects.
Healthcare & clinics
Appointment reminders that cut no-shows, plus a queue line that never rings out to voicemail.
Logistics & delivery
Live tracking links by SMS, driver escalation calls, and webhooks straight into your dispatch system.
Education
Fee reminders, exam results and parent broadcasts from one sender ID across three languages.
Government & PSU
Data hosted in India, DPDP Act-aligned processing and procurement paperwork we have done before.

Engineering
When the off-the-shelf answer does not fit
We keep an in-house team in Nangloi for the systems our platform products cannot cover — internal tools, ERP integrations, mobile apps. They also have to support what they ship, which changes how it gets built.
- Web application development
- iOS and Android apps
- API design and development
- ERP and accounting integration
- Legacy system modernisation
- Cloud migration and DevOps
- Technical due diligence
- Maintenance and support retainers
Getting started
Three moves, usually inside a month
- 01
Tell us the volume and the systems
How many messages, calls or outlets, and what has to talk to what. Twenty minutes on a call is usually enough to scope it.
- 02
Run a pilot on real traffic
One campaign, one queue or one outlet, live within days. You see actual delivery rates on your own numbers before signing anything.
- 03
Roll out with a named engineer
Migration, training and integration handled by the same person who ran your pilot. They stay on the account afterwards.
Tell us what is not working right now
A 20-minute call, no deck. Describe the channel, the volume and the system it has to talk to, and we will tell you whether we are the right fit — including when we are not.
