The facts

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, McDonald's, 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 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 publishes a first-party MCP server. Its developer documentation describes AI clients such as Claude, ChatGPT and Cursor connecting to a workspace and calling tools including get_contact, send_message and create_comment over HTTP and STDIO, and the vendor says agents can be managed directly from Claude or ChatGPT. Channels include WhatsApp and the WhatsApp Business Calling API, Instagram, TikTok, Facebook Messenger, Telegram, LINE, WeChat, Viber, SMS, 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. Pricing verified live on respond.io/pricing in September 2026, where the page states that prices are in USD. Plans are priced by Monthly Active Contacts, the contacts a business talks to in a month, starting at 1,000. 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. Growth is $159 per month billed yearly or $199 month to month, with 10 users and extra users at $20. Advanced is $279 per month billed yearly or $349 month to month, with 10 users, extra users at $24, 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. 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. Current state Q3 2026: the 2026 Series B is earmarked for expansion into North America and Europe, AI Agents handle voice calls over WhatsApp and VoIP, and Diskat, an e-commerce retailer in Guatemala, reports 90% of sales handled by AI Agents, an 81.4% conversion rate and a 50% reduction in marketing and operational costs.

Pros & Limitations

Editorial assessment

Pros

  • ✓Publishes a first-party MCP server that AI clients including Claude, ChatGPT and Cursor connect to over HTTP and STDIO, and AI Agents can be managed directly from Claude or ChatGPT.
  • ✓Broad channel coverage in one inbox, from WhatsApp, Instagram, TikTok, Messenger, Telegram, LINE, WeChat and Viber to SMS, VoIP calls and email, backed by official Meta and TikTok partnerships.
  • ✓AI Agents that qualify leads, book appointments, update the CRM and answer voice calls in more than 30 languages, with AI usage included on Growth and above and a privacy policy that rules out training on customer content.

Limitations

  • –The trust center lists ISO 27001 and GDPR only, so buyers who need a SOC 2 report or HIPAA coverage should confirm them with the vendor before procurement.
  • –Monthly Active Contact pricing scales with the number of contacts reached rather than with resolved conversations, and WhatsApp fees from Meta are billed on top, which makes costs harder to forecast at high volume.
  • –AI Agents are not part of the Starter plan, and the Advanced and Enterprise plans are bought through sales rather than a self-serve checkout, with Enterprise pricing not published.

Autonomous rateAI Agents handle customer conversations end to end without per-message approval, qualifying leads, updating CRM fields and lifecycle stages, recommending products, booking appointments and closing conversations, and escalate to a person when a conversation needs judgment. Diskat, an e-commerce retailer in Guatemala, reports 90% of sales handled by AI Agents, which is one customer's result rather than a platform-wide benchmark.
