Tact.ai

Tact.ai was a Redwood City, California conversational-AI and field-engagement company founded by Chuck Ganapathi that built an AI sales assistant ("Tact Assistant") unifying CRM, email, and calendar data into a voice- and chat-driven interface for enterprise sales teams, later concentrating on the life sciences vertical. It was backed by Accel, Redpoint Ventures, Upfront Ventures, Microsoft's M12, and Salesforce Ventures. In November 2023 its field-engagement and conversational-AI technology was acquired by Aktana and the standalone company wound down. The tact.ai domain no longer hosts a product: it resolves to an Afternic domain-for-sale parking page (nameservers ns1/ns2.afternic.com), and the company exposes no public developer API, documentation, or developer portal to enrich.

Tact.ai is profiled on the APIs.io network. Tagged areas include Company, Enterprise, Conversational AI, Sales, and CRM.
