Knock is hardening for enterprise buyers while its agent takes over the analysis work.
Knock ships weekly, in small, legible increments across three lanes: account governance (custom roles, passkeys), workflow primitives (wait-for-event, branch rebasing), and data ingress (Amplitude, Clay). The newest entry adds granular custom roles, which closes the last obvious gap in account-level access control. Alongside that, the in-product agent gained analytics, letting teams interrogate delivery performance without building reports.
Sentry is pushing past collection into interpretation, with Seer and AI-generated dashboards.
Two AI surfaces now anchor the changelog: the Seer agent in open beta and an AI dashboard-generation beta. Underneath, the platform keeps broadening ingestion and alerting — metrics reach .NET and Unity, logs reach Kotlin Multiplatform, uptime monitors gain alert configuration, metrics beta gains alerting, and Alerts is splitting into Monitors and Alerts. Size Analysis and org-level Data Forwarding reached GA.

Two arcs run in parallel. The infrastructure lane is buying enterprise credibility — roles, passkeys, audit-grade permissions — the checklist items that decide procurement rather than daily use. The data lane keeps widening what can trigger a workflow: product analytics from Amplitude, enriched rows from Clay, internal Slack channels as a destination. Together they push Knock from a notification API toward the messaging control plane, with the agent as the layer that explains what the plane did.
Expect the roles work to continue into audit logs or scoped API keys, since granular permissions without an activity trail is an incomplete enterprise story. More data sources are likely on the same cadence, with the CRM and warehouse categories the obvious remaining gaps.

The consistent direction is reducing the setup and expertise required before a signal becomes visible. Generating dashboards and answering questions about the app are both attacks on the same cost: the engineer who has to know what to build before they can see anything. Meanwhile SDK and alerting coverage keeps filling in as table stakes.
Look for the AI surfaces to converge — Seer and generated dashboards becoming one investigation path rather than two features — and for the Monitors/Alerts split to settle into clearer routing.
