TalkStack AI is a San Francisco-based AI agent platform founded in 2023 by Eunice Wong (CEO) and Pasquale Sorrentino. The platform lets businesses scale customer support and sales operations by deploying AI agents that can handle thousands of simultaneous conversations across voice calls, text, WhatsApp, and SMS channels without requiring any coding from the user. The platform is designed to automate Tier 1 and Tier 2 support cases, with TalkStack claiming up to 90% of such cases can be handled autonomously and reporting 98% automation rates in active deployments. Agents can be configured via a no-code dashboard where users clone voice, tone, style, and knowledge base to match their brand. TalkStack supports over 20 languages including Asian languages, enabling globally distributed businesses to serve customers in their native language. Integration capabilities span major CRM and ERP systems including Zendesk, SAP ERP, Gmail, and Slack, with an API-driven framework for custom connections to databases and third-party messaging platforms. The company was backed by Techstars in a pre-seed round of $120K in October 2023 and launched publicly on Product Hunt in February 2026. It targets mid-market and enterprise customers in sales, customer support, and operations who want to reduce contact center headcount while maintaining 24/7 availability.
