Intercom is an AI-first customer service company best known for Fin, its AI agent that resolves customer support conversations automatically.

Hiver is a customer service platform built on top of Gmail and Google Workspace.

Founded in 2011 (originally as GrexIt), Hiver now serves more than 10,000 organizations, including Harvard University, Flexport, and Upwork, and has expanded into AI-assisted support across email, live chat, voice, and WhatsApp.
Front
Front is a customer service platform that unifies email, chat, SMS, social and voice into one collaborative workspace. It looks like an inbox, behaves like a help desk, and adds AI on top so teams can answer faster without losing the human voice their customers hired them for.
