Superhuman bets on agent-operable email: a Codex plugin now drives the inbox.
A side-by-side editorial comparison of Fellow and Twilio — release velocity, themes, recent moves, and the top alternatives to consider.
Fellow's public changelog has been silent since 2021 — no recent direction is observable here.
The visible signal stops in spring 2021. The last few releases were calendar-extension touch-ups: action items appearing directly in the Google Calendar extension, public view-only meeting links for external attendees, and multi-calendar sync within a single Google or Office account. Nothing in this dataset reflects the past several years of Fellow's actual work.
Twilio fills out EU data residency, RBAC, and unified messaging APIs
Twilio's changelog is a steady run of platform releases. This window centers on enterprise controls and regional expansion: Enhanced RBAC reaching GA in the new Console, EU (IE1) data residency for SMS GA and Studio/TaskRouter in private beta, a unified V3 typing-indicator API across RCS/WhatsApp/AMB, and a SIP call-forwarding beta.
The visible signal stops in spring 2021.

Nothing in this dataset reflects the past several years of Fellow's actual work.
From the entries alone, no current trajectory can be inferred — the data is years stale. Whether Fellow has shifted to AI-meeting-notes or remained focused on the original meeting-management surface is not visible here and would be guesswork to assert.
Predictions can't be grounded in this data. The most useful next step is to refresh Fellow's changelog source so that present-day moves are captured.
Twilio's changelog is a steady run of platform releases. This window centers on enterprise controls and regional expansion: Enhanced RBAC reaching GA in the new Console, EU (IE1) data residency for SMS GA and Studio/TaskRouter in private beta, a unified V3 typing-indicator API across RCS/WhatsApp/AMB, and a SIP call-forwarding beta.
Twilio is hardening the platform for regulated, multinational customers — granular access control, EU data residency across more products, and consistent cross-channel messaging APIs. The arc is enterprise-readiness and channel unification on top of the existing CPaaS surface, with its agent SDK (Agent Connect) building separately.
Expect more regional data-residency GAs and continued channel-API unification, alongside buildout of the AI agent SDK announced earlier.
