3Sigma vs Kylas: WhatsApp and Calling Built In vs Add-On
Kylas is a solid Indian CRM — but WhatsApp is an add-on integration. 3Sigma has WhatsApp Business API and SIM-based calling built into the core, plus direct IndiaMart and JustDial lead capture. Here is how to choose.
The short answer
Kylas is a web-first Indian CRM with good pipeline management — WhatsApp and advanced calling require third-party integrations. 3Sigma is a WhatsApp-first, mobile-first CRM where WhatsApp Business API, SIM-based auto-dialer, IndiaMart and JustDial leads are all built into the core. If WhatsApp and calling are how your team sells every day, 3Sigma is designed for that combination.

The WhatsApp difference
Most Indian sales teams send more WhatsApp messages than emails in a day. When WhatsApp is connected via a third-party API platform, you end up with conversations split across two tools and no single view of a lead's full history.
In 3Sigma, every WhatsApp message, every call and every follow-up note lands on the same lead timeline. When Priya from your Delhi team calls Arjun Kapoor, she can see his last WhatsApp message, the quote sent yesterday and the open task — all before the call connects. That is what a real WhatsApp CRM looks like.
Shared WhatsApp inbox
All team chats in one inbox — assigned by source, product or rep. No private numbers, no lost conversations.
Broadcasts and drip sequences
Send bulk campaigns and multi-day follow-up sequences that stop automatically on reply — no more chasing on spreadsheets.
WhatsApp Coexistence
Connect your existing WhatsApp Business number and keep using the app on your phone. Chat history syncs in; no new number needed.
Message then call — same app
Chat the lead on WhatsApp, then dial them on your SIM. Both are logged on the same lead timeline automatically.
Lead capture from Indian portals — built in
A manufacturer in Rajkot, a service provider in Bengaluru, a real estate developer in Pune — they all get leads from IndiaMart, JustDial and 99acres. 3Sigma connects directly to these portals: leads flow in, get auto-assigned and a WhatsApp follow-up fires in seconds. No Zapier, no copy-paste, no delay.
SIM-based calling — no per-minute cost
Cloud telephony platforms charge per minute. When your team is making dozens of calls a day, that adds up fast. 3Sigma's auto-dialer runs on the agent's own SIM card — any Indian network, dual-SIM supported, no cloud cost per call.
Back-to-back auto-dialer
Dial your entire lead list in sequence — the dialer advances automatically after each call, with a countdown between calls.
100% auto-logged
Duration, outcome and notes are captured automatically on every call — without the rep needing to update anything.
Crash-proof sessions
If the app restarts mid-list, the dialer session resumes from the exact lead you left off on — no one falls through the cracks.
Caller leaderboard
A live leaderboard ranks your team by calls made and talk time — useful for sales managers running a calling team.

How to choose
Pick Kylas if…
Your team works from laptops, does not rely heavily on WhatsApp for daily sales, and wants a clean web-based CRM with solid pipeline management and email. Kylas is a well-designed product for that use case.
Pick 3Sigma if…
Your salespeople are on the phone all day — calling on their SIM and messaging on WhatsApp. You get leads from IndiaMart, JustDial or Facebook. Your team is on the road (field tracking) or sends quotations and invoices on the go. That is most Indian SMBs — and 3Sigma is built exactly for that.
FAQs — 3Sigma vs Kylas
What is the difference between 3Sigma CRM and Kylas?
Both are Indian SaaS CRMs built for SMBs. Kylas is a traditional pipeline CRM — solid lead management and a web-first interface. 3Sigma is a WhatsApp-first, mobile-first CRM — WhatsApp Business API, SIM-based auto-dialer, and direct lead capture from IndiaMart and JustDial are built into the core, not added via integrations. If your team sells primarily on WhatsApp and calls, 3Sigma is designed for that combination.
Does Kylas have WhatsApp built in?
Kylas offers WhatsApp as an integration — you need to connect a third-party WhatsApp API provider separately. In 3Sigma, WhatsApp Business API — shared inbox, broadcasts, drip sequences, no-code chatbots and AI bot — is part of the core product. There is no extra platform fee for WhatsApp itself (Meta's conversation charges apply regardless of which CRM you use).
Which is better for a mobile sales team?
3Sigma is built mobile-first — leads, WhatsApp, calls, the SIM auto-dialer, quotations and live team tracking all run from the Android app, with iOS available on the Ultimate plan. Kylas is primarily a web app. If your salespeople are on the phone all day, 3Sigma's mobile experience is more complete.
Both have calling — what is different about 3Sigma's calling?
3Sigma's calling is SIM-based — your agent calls from their own SIM card on any Indian network, with no per-minute cloud telephony cost. The auto-dialer works through a list back-to-back, every call is 100% auto-logged, and a caller leaderboard tracks the team live. Kylas has calling integration with cloud telephony providers where per-minute rates apply. The SIM-based approach is a meaningful cost difference for teams making large call volumes.
Does 3Sigma have IndiaMart and JustDial lead capture?
Yes — both are built-in integrations in 3Sigma. Every IndiaMart enquiry and JustDial lead flows into the CRM automatically, is auto-assigned and gets a WhatsApp follow-up in seconds. This matters for Indian manufacturing, retail and service businesses where B2B portals are a primary lead source. Kylas requires a third-party connector to achieve the same.
Which should I pick — 3Sigma or Kylas?
If your sales team spends most of their day calling on their SIM and messaging on WhatsApp, captures leads from IndiaMart and JustDial, and needs the whole workflow on mobile, 3Sigma is built for that. If you have a desk-based team using a web browser and want a clean traditional CRM with solid pipeline management, Kylas is a reasonable choice. The key question is: how central is WhatsApp and calling to your daily sales process?
