What is Respond.io?
Respond.io builds out Voice AI agents and automated inbox hygiene
Respond.io is shipping a steady run of real product features across two tracks: AI automation (Voice AI agents that hand live calls to humans, multi-model failover under the hood, ad-aware and online-only assignment) and messaging operations (auto-closing inactive conversations with AI-generated summaries, custom Facebook Messenger templates, a 'Call on WhatsApp' button, and a refreshed mobile experience). A webhook-domain migration improves integration reliability.
What is Heymarket?
Heymarket layers AI agents and structure onto business messaging
Heymarket's feed mixes marketing content with a real product track: it has introduced Escalations for routing urgent conversations, Conversation Tags for structure, inbound webhooks for tech-stack integration, and email-alongside-SMS in Salesforce and HubSpot. A behind-the-scenes post on training its AI agents (and dogfooding them) signals where the roadmap is heading.

Respond.io builds out Voice AI agents and automated inbox hygiene
◆ Current state
Respond.io is shipping a steady run of real product features across two tracks: AI automation (Voice AI agents that hand live calls to humans, multi-model failover under the hood, ad-aware and online-only assignment) and messaging operations (auto-closing inactive conversations with AI-generated summaries, custom Facebook Messenger templates, a 'Call on WhatsApp' button, and a refreshed mobile experience). A webhook-domain migration improves integration reliability.
◆ Where it's heading
The product is converging on AI-run conversations with humans in the loop — voice and text agents that escalate, fall back across models, and use ad and presence context — wrapped in cleaner inbox operations and reporting. Expect deeper Voice AI capabilities and more automation around conversation lifecycle and routing.
◆ Prediction
Next moves likely extend the Voice AI agent (more transfer logic, broader channel coverage) and push AI-driven automation deeper into routing, summarization, and reporting.

Heymarket layers AI agents and structure onto business messaging
◆ Current state
Heymarket's feed mixes marketing content with a real product track: it has introduced Escalations for routing urgent conversations, Conversation Tags for structure, inbound webhooks for tech-stack integration, and email-alongside-SMS in Salesforce and HubSpot. A behind-the-scenes post on training its AI agents (and dogfooding them) signals where the roadmap is heading.
◆ Where it's heading
The product is evolving from team SMS toward a structured, AI-assisted omnichannel support layer that plugs into CRMs and arbitrary systems via webhooks. Escalations and Tags add operational rigor; the AI-agents work points toward more automated handling of inbound volume. Expect deeper AI-agent capabilities and broader channel/CRM coverage.
◆ Prediction
Next moves likely productize the AI agents Heymarket has been training internally, with more automation around triage, escalation, and response drafting across its messaging channels.
