Braze is in steady-ops mode; the AI content-optimization bet from earlier in 2026 still sets the tone.
The top of Braze's feed reads as housekeeping. Banner channel fields are being filled into Currents and Datashare exports, a Quick User Add workflow has appeared inside Import Users, and a JP-01 data center has come online. The substantive AI move for the period was Content Optimizer in early February — a continuous, AI-variant testing step inside Canvas — and that work is no longer at the front of the changelog.
Gumloop launched automatic model routing, a proactive self-improving agent (Gumball), and voice calling in six weeks of dense shipping.
Gumloop has been shipping on multiple fronts at high velocity: the Model Router that picks models per task automatically, the Gumball launch as a proactive self-improving agent in company cloud, a rebuilt agent builder that simplifies setup, background subagent execution, voice calling for agents, and continuous model roster expansion. The product has moved from workflow automation tool to a full agentic platform with its own intelligence layer on top of third-party models.
The top of Braze's feed reads as housekeeping.

The substantive AI move for the period was Content Optimizer in early February — a continuous, AI-variant testing step inside Canvas — and that work is no longer at the front of the changelog.
The cadence is incremental enterprise plumbing rather than directional product reinvention: new channel fields where customers asked, regional residency, small UX additions to user import. The product motion that matters is downstream of Content Optimizer — the bet that AI-generated message variants become the default authoring path in Canvas — and the recent shipping doesn't yet show how that bet is being expanded.
More Currents and Datashare schema additions for newer channels are likely, alongside follow-on Content Optimizer features (more variant types, deeper Liquid integration). If JP-01 is the start of a regional rollout rather than a one-off, expect another non-US region announcement within a quarter or two.
Gumloop has been shipping on multiple fronts at high velocity: the Model Router that picks models per task automatically, the Gumball launch as a proactive self-improving agent in company cloud, a rebuilt agent builder that simplifies setup, background subagent execution, voice calling for agents, and continuous model roster expansion. The product has moved from workflow automation tool to a full agentic platform with its own intelligence layer on top of third-party models.
Gumloop is building the abstraction layer above models—automatic routing, unified connectors, artifact-first outputs, background subagent execution, and voice input. The introduction of Gumball points toward a consumer-facing AI product alongside the developer-focused automation platform, potentially broadening the addressable user base significantly. The self-improvement angle is speculative until more detail ships, but combined with the model router it represents a clear bet on abstracting model selection away from end users entirely.
Voice input and Gumball's self-improvement loop suggest the next releases will deepen voice and proactive automation surfaces—likely more Gumball integrations, scheduled agent runs, or a Gumball mobile experience.
