Respond.io

Respond.io is a customer conversation platform that brings business messaging channels, calls and email into one AI-powered inbox, built for mid-market B2C businesses that earn revenue from customer chats and calls. It was founded in 2017 and is headquartered in Kuala Lumpur, Malaysia, and the vendor reports more than 10,000 businesses across 180+ countries. Its homepage shows Toyota, British Airways, Radisson Hotel, Hertz and Decathlon under the heading "10k+ brands trust respond.io". Respond.io raised a $62.5 million Series B led by Camber Partners in 2026, and it names official partnerships with Meta, TikTok, OpenAI and AWS.

AI Agents are autonomous, role-based agents that handle conversations from the first message to resolution. They detect intent, work with text, images, PDFs and voice notes, update CRM fields and lifecycle stages, book appointments, recommend products and escalate to a person or another agent. Pre-built sales, support and receptionist templates speed up setup, an AI-guided builder drafts a tested agent from a plain-language description, and on Advanced and Enterprise, AI Agents answer WhatsApp and VoIP voice calls in more than 30 languages with recording, summary and transcript. Respond.io publishes its AI subprocessors: OpenAI and Mistral AI for language model inference, Mistral AI for OCR of PDFs and images in knowledge sources, Google Cloud Vertex AI for embeddings and translation, ElevenLabs for voice, and LangSmith for observability.

Respond.io runs a hosted, first-party MCP server. AI assistants such as Claude and ChatGPT connect to it with OAuth from their connector directories to look up and update contacts, send messages and templates and review conversation history, and the vendor says agents can be managed directly from Claude or ChatGPT. Through the MCP server, assistants can also build, test and publish Workflows, which are on Growth and above. An earlier local MCP server that runs over STDIO or HTTP is now documented as legacy. Channels include WhatsApp and the WhatsApp Business Calling API, Instagram, TikTok (in beta), Facebook Messenger, Telegram, LINE, WeChat, Viber, SMS, RCS through Twilio, VoIP calls, email and web chat. Integrations include HubSpot, Salesforce, Pipedrive, Zendesk, Shopify, WooCommerce and Magento, Zapier, Make.com and n8n for automation, Cal.com, Calendly and Google Calendar for booking, and Meta and TikTok ads for lead capture.

Respond.io's pricing page states that prices are in USD. Growth and Advanced are priced by Monthly Active Contacts, the contacts a business talks to in a month, starting at 1,000, with extra contacts billed at $12 per 100 on Growth and $15 per 100 on Advanced. Starter has no contact limit. Starter is $79 per month billed yearly ($948 a year) or $99 month to month, with 5 users and extra users at $12 a month on yearly billing or $15 month to month. Growth is $159 per month billed yearly or $199 month to month, with 10 users and extra users at $20 a month on yearly billing or $25 month to month. Advanced is $279 per month billed yearly or $349 month to month, with 10 users, extra users at $24 a month on yearly billing or $30 month to month, Salesforce, SSO and multiple workspaces, and it is bought through sales. Enterprise is custom, with unlimited users and higher API rate limits. AI usage is included on Growth, Advanced and Enterprise, with AI credits that start at 10,000, 20,000 and 40,000 a month and grow with the contact tier, and credits beyond the allowance cost $15 per 1,000 up to a cap of 200% of the allowance. Starter includes 5,000 AI credits for AI Assist and chat summaries but not AI Agents or Workflows. WhatsApp fees from Meta are charged on top of every plan. A 7-day free trial of the Growth plan needs no credit card, and there is no permanently free plan.

Respond.io's trust center lists ISO/IEC 27001 and GDPR, and its security page describes the company as ISO 27001 certified and GDPR compliant. Its privacy policy states that customer content, including message content and conversation history, is not used to train, develop or improve generalized or foundational AI models, and that third-party AI providers are not permitted to use it for those purposes.

Respond.io is built around chat-first revenue conversations. Teams that want a full help desk with ticketing, SLAs and a published knowledge base can look at Zendesk AI or Intercom Fin, and teams that only need WhatsApp broadcasts and chatbots in a simpler inbox can look at Wati.
