What is Knock?
Notifications infra doubles down on enterprise readiness — security, governance, and analytics
Knock, a developer-facing notifications platform, is in a steady cadence of platform-maturity releases. The recent window is heavy on account security (passkeys, TOTP MFA) and workspace governance (saved views, tags, schema management), plus a pipe to sync message delivery and engagement events into the data warehouse. These are the features enterprises audit for, layered on top of the core workflows/broadcasts/guides engine.
What is Merge?
A unified-API company is quietly rebuilding itself as AI-agent infrastructure
Merge ships dense weekly changelogs across three surfaces: the original Unified API (accounting, HRIS, ATS, CRM, file storage, ticketing), Agent Handler (governed tools and connectors for AI agents), and Merge Gateway (a model-routing and LLM-security layer). The Unified API work is steady maintenance — mapping enhancements, sync performance, and edge-case handling across dozens of integrations. The energy and net-new capability sit in Agent Handler and Gateway.

Notifications infra doubles down on enterprise readiness — security, governance, and analytics
◆ Current state
Knock, a developer-facing notifications platform, is in a steady cadence of platform-maturity releases. The recent window is heavy on account security (passkeys, TOTP MFA) and workspace governance (saved views, tags, schema management), plus a pipe to sync message delivery and engagement events into the data warehouse. These are the features enterprises audit for, layered on top of the core workflows/broadcasts/guides engine.
◆ Where it's heading
Knock is hardening for larger, security-conscious buyers: authentication and access controls are catching up to enterprise expectations, dashboard organization is scaling for bigger teams, and analytics is opening up via warehouse sync. Earlier moves — a Slack-triggered Knock agent and a Shopify data source — show the platform also broadening its inputs and interfaces, but the current emphasis is unmistakably on trust, governance, and observability rather than net-new notification capabilities.
◆ Prediction
Expect the enterprise-readiness push to continue with more access-control and audit features, and likely deeper analytics or SSO/provisioning work building on the warehouse-sync and MFA foundations.

A unified-API company is quietly rebuilding itself as AI-agent infrastructure
◆ Current state
Merge ships dense weekly changelogs across three surfaces: the original Unified API (accounting, HRIS, ATS, CRM, file storage, ticketing), Agent Handler (governed tools and connectors for AI agents), and Merge Gateway (a model-routing and LLM-security layer). The Unified API work is steady maintenance — mapping enhancements, sync performance, and edge-case handling across dozens of integrations. The energy and net-new capability sit in Agent Handler and Gateway.
◆ Where it's heading
Merge is levering its integration catalog into an agent-tooling and model-routing play. Gateway keeps adding frontier models, custom routing, and enterprise controls (RBAC, audit, prompt-injection protection, DLP), while Agent Handler expands connectors and observability. The through-line: the same normalized-integration muscle that powered unified data access is now being pointed at giving AI agents governed, routable access to tools and models. Unified API is the stable base; the growth vector is agent infrastructure.
◆ Prediction
Expect Gateway to keep absorbing new frontier models and routing controls on a weekly cadence, and Agent Handler to keep converting existing Unified API integrations into agent-callable connectors.
