Respond.io

Respond.io builds a single inbox where teams manage chats, calls, and emails across WhatsApp, Messenger, TikTok, Facebook, and your CRM — no more bouncing between platforms. When customers switch channels mid-conversation, the context stays intact.

Their AI Agents qualify leads and answer basic questions so your team focuses on deals that matter. The core problem they solve: businesses drowning in customer messages across fragmented channels. When you're scaling via ads, every missed message or dropped conversation is lost revenue.

They've built this for mid-market B2C companies that have outgrown lightweight tools but don't need enterprise bloat. Over 10,000 brands trust them — Toyota, McDonald's, British Airways. Founded in 2017 in Hong Kong as Rocketbots (raised seed funding in 2018), then relocated to Kuala Lumpur in 2019. Series A in 2022 ($7M from Headline Asia).

They've added AI capabilities, native customer lifecycle management, and recently got selected for Meta's WhatsApp Business Calling.

If you're in Southeast Asia (they're based in KL), this is a company building real infrastructure for high-volume customer conversations — the kind that drive actual revenue.
