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 Optimizely?
Optimizely's public release feed is mostly roadmap scaffolding, with Opal AI as the visible bet.
The available updates are largely roadmap-page navigation and legal disclaimers rather than concrete release notes. The one substantive signal is the existence of a dedicated Opal AI roadmap surface, indicating the company is publicly anchoring its AI work under the Opal brand. Actual feature shipping cadence isn't visible through this channel.

Knock
6.3INFRA · APIS
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.
Optimizely
0.0INFRA · APIS
Optimizely's public release feed is mostly roadmap scaffolding, with Opal AI as the visible bet.
◆ Current state
The available updates are largely roadmap-page navigation and legal disclaimers rather than concrete release notes. The one substantive signal is the existence of a dedicated Opal AI roadmap surface, indicating the company is publicly anchoring its AI work under the Opal brand. Actual feature shipping cadence isn't visible through this channel.
◆ Where it's heading
Optimizely appears to be repositioning publicly around Opal AI as the unifying narrative across content marketing, experimentation, personalization, and commerce. The dominant safe-harbor disclaimer language suggests the AI roadmap is still being marketed ahead of broad availability. Without concrete shipped features in the feed, it's hard to gauge real velocity.
◆ Prediction
Expect the Opal AI roadmap page to start filling in with shipped, branded capabilities (likely first in Personalization and Content Marketing where Optimizely has the most data leverage) rather than a single big launch.
