The AI-powered B2C CRM for email, SMS, and personalized marketing at scale
Every contact, event, and channel feeds one profile so segmentation, personalization, and reporting stay consistent.
An agent that plans calendars, drafts campaigns, audits flows, and recommends next actions using your business context.
Build campaigns and automated flows across email, SMS, RCS, WhatsApp, push, and social from one interface.
Forecast lifetime value, churn risk, and expected next purchase date to target the right customers at the right time.

Build hyperrealistic voice agents on any AI stack, then run them on real phone calls
Abstracts speech-to-text, text-to-speech and LLM calls so you can swap vendors such as different STT, TTS and language model providers without rewriting your call flow.
Handles inbound and outbound phone calls with number provisioning, call creation, recording retrieval and CDR-style usage endpoints exposed through a documented REST API.
Register webhooks and self-contained actions so an agent can look things up, transfer a caller, or trigger work in your backend mid-conversation.
Supports streaming or turn-based conversation modes, endpointing and emotion tracking, plus browser and meeting-based interfaces beyond pure telephony.
