Voice & conversation AI · India + global
One agent. Every channel. Every language.
Deploy AI agents that talk on voice, WhatsApp, RCS, SMS, email, Instagram and Telegram — from a single low-code flow. Integrate with the CRM and marketing stack you already use. Ship in days, not quarters.
No code. No long onboarding. Three steps and your first agent is taking calls.
01 · design
Build the flow.
Use the low-code drag-and-drop builder, or describe the agent in three sentences and we generate the workflow. Edit nodes, prompts, branches, webhooks — all visual.
02 · test
Call it from your browser.
Web-call the agent the moment it's saved. No SIM, no telecom integration required. Run it against an AI persona that role-plays your worst customer to harden it before a real one calls.
03 · deploy
Wire it to a phone number — or seven channels.
Plug in Twilio, Telnyx, Vonage, Cloudonix, Vobiz, or your own Asterisk. Same flow ships to WhatsApp, RCS, SMS, Email, Instagram, and Telegram. One bill, per-second.
§ 02 — hear the voice
Three demos. Production voices, your voice, the room.
Press play on any card. (Audio samples ship later this week — placeholders shown.)

0:12audio loading soon · placeholder
§ 03 — the stack
One platform. Five layers. No black boxes.
Zapim owns the full pipeline — telephony, voice synthesis, retrieval, orchestration, evaluation. Nothing between your agent and the caller is a third-party API in the critical path.
01
telephony
Zapim Telephony
Six telephony backends (Twilio, Telnyx, Vonage, Cloudonix, Vobiz, Asterisk-ARI) with one inbound webhook URL. Round-robin caller-ID rotation atomic across distributed workers.

Data sovereignty.
Audio, transcripts, and embeddings stay in your region. India (Mumbai), EU (Frankfurt), and US available. On-prem deployment for enterprise.
No third-party black boxes.
No external APIs in the critical voice path. No surprise deprecations, price changes, or outages outside our control.
One SLA.
Single team accountable for latency, uptime, and quality across the full stack. One throat to choke. One pager to ring.
§ 04 — bot flow builder
Low-code by default. Code when you need it.
Drag-and-drop nodes for greetings, branches, transfers, webhooks, and tools. Drop into JSON when the design needs surgery.
Visual nodes, real logic.
Every node is a typed object — greeting, agent, branch, webhook, transfer, end-call, custom tool. Branches use real LLM-evaluated conditions, not regex.
5 prebuilt templates.
Outbound follow-up, inbound triage, appointment reminder, lead qualifier, and a Hindi-English bilingual greeter. Pick one, edit prompts, ship.
Code when needed.
Every visual flow has a JSON view. Diff it, version it, paste it into CI. Custom HTTP tools for anything not in the standard library.
Test before you ship.
Web-call any flow from the dashboard. Run it against an AI persona to find the edge cases. Compare two versions side-by-side on the same script.
§ 05 — every market
Speak the language your customer answers in.
Production-ready voices in major languages worldwide, plus bring-your-own keys for every dialect on top. Mid-call code-switching is first-class.

§ 09 — global telephony
Test any country, before signing a telco contract.
Our native Asterisk-ARI bridge lets you spin up phone numbers in any country we have a SIP-trunk relationship with — or your own. Pilot in days, not procurement cycles.
Pilot in any country, day one.
SIP-trunk + Asterisk-ARI means you can plug in your own carrier credentials — or use ours — and start dialing without a procurement cycle.
Carrier-agnostic.
Same workflow runs on Twilio, Telnyx, Vonage, Cloudonix, Vobiz, or raw Asterisk. Switch carriers mid-campaign without re-writing the agent.
One inbound webhook, every provider.
Paste a single URL into Twilio, Telnyx, Vonage, Cloudonix, Vobiz, or Asterisk. We verify the signature per-provider on our side.
Round-robin CLI rotation.
When you outbound with 50 numbers, every worker process picks the next one atomically via Redis — no duplicates, no skew.
§ 10 — versus
Side-by-side with the alternatives.
Honest comparison against the Indian + global rivals you're already evaluating. If we get one wrong, tell us.

§ 11 — partner program
Run your own voice-AI brand. We're the engine.
An exclusive partnership model: a fully white-labeled Zapim platform under your brand, your domain, your pricing. We handle the infra; you own the customer.
What you get
Full white-label.
Your platform name, logo, color, custom subdomain or domain. Your tenants never see "Zapim" anywhere.
Multi-tenant from day one.
Provision unlimited end-customers under your account. Each tenant has its own users, RBAC, audit log, billing meter.
Your pricing, your margin.
Set your own per-second or per-conversation rate. We bill you wholesale; you bill your customers retail. We never see your customer.
Co-engineering on tap.
Direct access to our team for custom voice models, custom telephony peering, regional compliance work, and pilot-stage feature requests.
Exclusivity windows.
Geographic or vertical exclusivity available on the Flagship tier — if you're going hard at insurance in Tier-2 India, we don't sign your competitor.
