Respond.io raises $62.5M Series B to expand its customer conversation management platform globally

Today, respond.io raised $62.5 million in a Series B, led by Camber Partners with participation from Endeavor Catalyst and existing investors. This round accelerates respond.io's global expansion as the customer conversation management platform for mid-market B2C businesses that generate revenue from customer chats and calls.

While Series B raises tend to fund operations for SaaS companies, we stand at $35M ARR with 169% year-over-year growth as adoption increases steadily. After building a strong portfolio of customers in APAC, LATAM and EMEA, we’re using this funding to accelerate local acquisitions and build a stronger regional presence for businesses in North America and Europe.

How respond.io's infrastructure makes AI Agents commercially reliable

Since our $7 million Series A in 2022, we have expanded into voice calling, deeper channel integrations and AI Agents. As a Meta Business Partner and TikTok Marketing Partner, respond.io was selected for early rollouts of WhatsApp Business Calling API, TikTok Business Messaging and TikTok Messaging Ads, making us one of the first platforms offering end-to-end integrations across both messaging and calling.

AI is central to our appeal as a partner and how we enable businesses to scale. Most people think AI is what makes a conversation platform powerful. We think the conversation infrastructure is what makes AI powerful. AI without routing logic, conversation history, channel coverage, CRM context and human handoff is just a chatbot, while lightweight AI-first platforms aren't able to support the conversation volumes AI handles.

Our advantage is structural and compounds over time. Processing over 2 billion messages per quarter — more than any comparable platform — over the years allows us to aggregate intelligence about how businesses actually need AI to assist them.

As a result, our AI Agents handle real revenue conversations — grounded in verified business knowledge, tested before going live and designed to hand off to a human when necessary. They don't sit on the platform as an add-on product; they operate inside your routing logic, conversation history, CRM context and workflow automation. That is what gives our AI Agents commercial reliability, not just conversational fluency.

To make this happen, we work with technology partners like Amazon Web Services and OpenAI to create the infrastructure capable of scale, accuracy and speed. Respond.io is architecturally designed for 99.999% uptime even while processing over 2 billion messages per quarter, with AI integrated into platform and CRM context as a persistent intelligence layer.

Built in the markets that moved first

Respond.io grew in the markets where customer conversations were directly tied to sales, marketing and retention before anywhere else. APAC, LATAM and EMEA were messaging-first as early as the mid 2010s, inspiring our founding in 2017.

When a customer in Singapore, Mexico or Kuwait buys a car or a spa treatment, the whole transaction often happens inside a conversation — no forms, portals, or waiting for a callback. These businesses navigate WhatsApp, Instagram, TikTok, Messenger, Telegram, voice calls, live chat, email and more with distributed teams, fast response expectations and a direct link between conversation quality and commercial outcomes.

The results are measurable with respond.io customers seeing ROI in months, not quarters. Turkish online marketplace noonmar saw 40% more customers within 4 weeks of handling ad enquiries on respond.io. Malaysian specialty coffee retailer Lamarsa Coffee grew sales by 50% quarter-on-quarter across 6 countries while Spanish online holistic health service Doctor Heal has 62% faster appointment bookings for 3x more leads with respond.io's AI Agents at no additional headcount.

Now, North America and Europe are moving in the same direction. Social commerce on TikTok, Instagram and WhatsApp is growing quickly here and businesses offering high-consideration products or services will need a platform that can handle high volumes of conversations per week to help customers decide, buy or book appointments before they lose interest or find a competitor.

Stronger regional presence and improved platform for revenue generation

The investors’ profile for this round affirms respond.io’s business fundamentals and trajectory. Camber Partners is a New York City-based growth equity firm whose selective pre-fund portfolio includes Dropbox, PandaDoc, and Pipedrive — tools businesses around the world rely on daily — while Endeavor Catalyst is chaired by Reid Hoffman, co-founder of LinkedIn and Inflection AI. The return of our Series A investors indicates continued faith in respond.io, backing us to go even further in serving over 10,000 businesses in more than 180 countries.

This Series B capital injection means stronger local presence in existing regions, faster support and a more intelligent product ahead. As for B2C businesses in North America and Europe — across automotive, education, healthcare, beauty, retail, travel and beyond — this is the moment respond.io becomes more locally present in your region, not just available to it.

The direction has not changed. From the beginning, respond.io has built toward one thing: being the platform where revenue-generating customer conversations happen reliably at high volumes. This Series B funding allows us pursue this at greater speed and scale across more markets.
