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.

Group buying that cuts your cloud and AI bills for free
Pump buys reserved capacity across its customer base and passes the rate to you, with usage-drop risk staying on Pump's side rather than yours.
Set a quality bar once and each request routes to the cheapest model that clears it, with fallback chains so requests are not dropped when a provider is unavailable.
One budget per team covers cloud and AI spend together, with Slack warnings before limits are hit and the cost driver named.
Spend is checked every hour and anything unusual is traced back to the specific resource and the person responsible.
