Revenue model

1. SaaS Platform Subscription: Pricing is tailored to the size of the customer's contact list and how they'll use the platform. Every plan includes unlimited P2P sends, two-way texting, keyword triggers, smart links, polls & surveys with AI setup, CRM integrations, 10DLC registration, real-time analytics, role-based permissions, and dedicated CSM. The company offers quote-based pricing rather than publicly listed tiers.
2. Per-Message/Usage Fees: Variable usage-based component where customers pay per-message fees for SMS/MMS delivery, with lower costs for registered (10DLC) traffic compared to unregistered traffic. Network access fees vary by carrier and message type.
3. Securities Offering: SEC Form D notice filed March 2024 for a $2 million securities offering with $1.6 million already raised.
