Respond.io upgraded its AI Agents to GPT-5.6 and added TikTok Business Messaging for US accounts.
Respond.io is shipping across three tracks simultaneously: AI Agent improvements (GPT-5.6 model upgrade, pre-publish instruction review), channel expansion (TikTok Business Messaging for US, Microsoft 365/Outlook email), and workflow automation (missed call auto-follow-up, Google Calendar integration). The status persistence fix — keeping agents online as long as the tab is open — addresses a real reliability concern for teams that rely on online/offline presence for routing.
Service Fusion's feed stays on buyer guides, now an HVAC technician tool list.
Every recent Service Fusion entry is marketing content: a guide to must-have HVAC technician tools, a Kuhlman Electric case study, an idle-time guide, buyer guides by trade and team size, and a data migration checklist. None describes a product release.
Respond.io is shipping across three tracks simultaneously: AI Agent improvements (GPT-5.6 model upgrade, pre-publish instruction review), channel expansion (TikTok Business Messaging for US, Microsoft 365/Outlook email), and workflow automation (missed call auto-follow-up, Google Calendar integration). The status persistence fix — keeping agents online as long as the tab is open — addresses a real reliability concern for teams that rely on online/offline presence for routing.
The product is converging on a model where AI Agents handle routine conversations while human agents handle escalations, with channels increasingly auto-enrolled (missed calls become conversations, calendar events surface in the inbox). The channel expansion pace (TikTok, Microsoft 365, Google Calendar within weeks) suggests a deliberate push to cover every channel a business customer might use.
Voice channel integration — handling inbound calls with AI Agents rather than just converting missed calls into follow-ups — would complete the omnichannel picture respond.io is assembling.
Every recent Service Fusion entry is marketing content: a guide to must-have HVAC technician tools, a Kuhlman Electric case study, an idle-time guide, buyer guides by trade and team size, and a data migration checklist. None describes a product release.
The content targets growing trade businesses, HVAC, electrical and plumbing among them, and buyers comparing platforms. The case study puts phone integration and reporting forward as selling points, which suggests where the sales pitch is focused.
The feed carries no product releases, so the next shipped change is unclear. Expect more trade-specific guides and case studies.
