About LeadOS

LeadOS is a multi-tenant SaaS CRM built by DLanzer in Chennai, India, for small and medium businesses. It brings lead capture, scoring, outreach, and customer conversations into one place.

What we do

LeadOS helps Indian SMBs find and win more customers. Businesses capture leads from multiple sources, score and prioritise them, and reach out over WhatsApp, email, and SMS — then track every conversation and conversion from a single dashboard.

WhatsApp Business Cloud API

Our clients connect their own WhatsApp Business Account to LeadOS in one click using Meta’s official Embedded Signup. Once connected, LeadOS lets them:

  • Send and receive WhatsApp messages with their leads and customers.
  • Sync and send Meta-approved message templates for campaigns.
  • Automate welcome messages, away replies, and keyword-based responses.
  • Manage all conversations from a shared team inbox.

We use the official WhatsApp Business Cloud API so messaging is compliant and reliable. We access a client’s WhatsApp data only to operate the features they set up in their own account — see our Privacy Policy for details.
