Description

TalkStack AI provides human-like AI agents (such as its agent 'Joy') that handle customer support, sales, lead qualification, and appointment scheduling over voice calls and text messages around the clock. Agents can be created without coding by cloning a top agent's voice, tone, style, knowledge base, and use case from a dashboard, and support over 20 languages across omnichannel messaging. Teams can build custom multi-step workflows with checkpoints, calls, wait times, SMS, and WhatsApp reminders, and review every interaction as a chat transcript or recording.

Klaviyo is the leading marketing platform for ecommerce brands. With unified data from your tech stack, AI-powered insights, and powerful email + SMS automation, Klaviyo helps brands like Patagonia, Living Proof, and SoulCycle grow revenue.
