What is Knock?
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.
What is Stream?
Stream's logistics platform ships steady monthly digests: planning, orders, mobile, no pivots.
This feed is Stream, a delivery and transport-management platform (not the chat/video devtool of a similar name), publishing dated monthly release digests. Each month bundles dozens of scoped improvements across Planning, Orders, Vehicles, the driver mobile app, Public API, and reporting, plus a long fixes list. The cadence is reliable and the work is broad but incremental.

Knock

Knock is hardening for enterprise buyers while its agent takes over the analysis work.
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.
Stream
2.5INFRA · APIS
Stream's logistics platform ships steady monthly digests: planning, orders, mobile, no pivots.
◆ Current state
This feed is Stream, a delivery and transport-management platform (not the chat/video devtool of a similar name), publishing dated monthly release digests. Each month bundles dozens of scoped improvements across Planning, Orders, Vehicles, the driver mobile app, Public API, and reporting, plus a long fixes list. The cadence is reliable and the work is broad but incremental.
◆ Where it's heading
The arc is operational maturity, not repositioning: automatic run costing, an Operations Monitor, a rebuilt Clients screen, expanded Public API endpoints and webhooks, and continual planning/mobile refinement. It reads as a maturing vertical SaaS deepening its existing surface for logistics operators rather than opening new categories.
◆ Prediction
Expect the same monthly digest cadence with continued Public API and integration expansion and further planning/mobile polish; no directional shift is visible in these entries.
