What is Spike?

Spike grinds out incident-management ergonomics — number-comparison alerts, more integrations, broader AWS auto-resolution.

Spike is an incident management and on-call platform competing in PagerDuty's category. The recent quarter's releases are uniformly incremental — numeric comparison operators in Alert Rules, broader AWS auto-resolution coverage (now including SNS), Jenkins and NinjaOne integrations, an inbound Jira trigger, day-of-week alert routing, admin-managed Out of Office. Each release shaves friction from a specific operator workflow without changing what Spike fundamentally is.

What is Superhuman?

Superhuman bets on agent-operable email: a Codex plugin now drives the inbox.

Superhuman is pushing two threads: making the inbox drivable by AI agents, and refining its Split Inbox system. The newest move is a Codex plugin, built on its MCP, that lets Codex, Claude, and ChatGPT search, draft, triage, and act on mail using Superhuman-native primitives like Split Inbox and read statuses. Around it sit steady Split Inbox and mobile UX improvements.

Spike grinds out incident-management ergonomics — number-comparison alerts, more integrations, broader AWS auto-resolution.

◆ Current state

Spike is an incident management and on-call platform competing in PagerDuty's category. The recent quarter's releases are uniformly incremental — numeric comparison operators in Alert Rules, broader AWS auto-resolution coverage (now including SNS), Jenkins and NinjaOne integrations, an inbound Jira trigger, day-of-week alert routing, admin-managed Out of Office. Each release shaves friction from a specific operator workflow without changing what Spike fundamentally is.

◆ Where it's heading

Spike's competitive strategy reads as 'be more methodical about the long tail of operator paper-cuts.' The integration cadence is high — Jenkins, NinjaOne, Jira inbound, calendar links — the alert rule grammar keeps expanding (comparison operators, day-of-week conditions), and the on-call surface keeps gaining flexibility (gaps, scheduled layers, admin-managed OOO). No directional moves, but very consistent incremental velocity.

◆ Prediction

Expect more integration additions in the same vein (CI/CD tools, IT monitoring vendors), continued alert rule grammar expansion (time-of-day conditions and frequency-based thresholds are the obvious next axes), and more team-management features around on-call rotations.

S6.3

Superhuman bets on agent-operable email: a Codex plugin now drives the inbox.

◆ Current state

Superhuman is pushing two threads: making the inbox drivable by AI agents, and refining its Split Inbox system. The newest move is a Codex plugin, built on its MCP, that lets Codex, Claude, and ChatGPT search, draft, triage, and act on mail using Superhuman-native primitives like Split Inbox and read statuses. Around it sit steady Split Inbox and mobile UX improvements.

◆ Where it's heading

Superhuman is positioning itself as the email client AI agents operate, not just one humans use — its MCP, Draft Sync with Gmail and Outlook, and now a Codex plugin all point the same way. In parallel it keeps sharpening Split Inbox (reorder, hide-empty, a Reminders split) and mobile flow. The bet is agent-operability plus opinionated triage as the wedge against Gmail and Outlook.

◆ Prediction

Expect more agent surface — additional MCP hosts and agent-drivable actions — alongside continued Split Inbox personalization. The entries point to agentic email as the primary investment line.
