About

Reliable memory of market moves, built with people running agents.

Market Changelog is a founder-led, MCP-first product and Ohio-registered trade name currently evaluated through a small private pilot.

Founder-led and deliberately small

Jaylen Johnson, Founder, is building and operating Market Changelog as a focused competitive-intelligence layer for AI agents. MARKET CHANGELOG is an Ohio-registered trade name, Entity No. 5668239, effective August 20, 2026.

The product began with a practical problem: agents can find current pages, but recurring workflows need a durable record of what changed and evidence they can retrieve again. That led to an MCP-first service built around approved targets, leased monitoring work, stable change identifiers, and tenant-scoped access.

Current product stage

Market Changelog is in a private design-partner pilot for people and teams running agents. The current service supports manual workspace onboarding, revocable workspace credentials, up to five approved public pages by default, durable queued scans, and evidence retrieval through MCP.

There is no public self-service account flow, OAuth connection, billing system, marketplace listing, human analytics dashboard, or service-level agreement today. Pilot access is reviewed and provisioned manually.

Operating principles

Evidence before inferenceAgents should inspect a stored source transition before presenting a conclusion.

Authority stays server-sideWorkspace access comes from the verified connection, not prompt text.

Public targets onlyPilot targets are operator-reviewed public pages, not authenticated application screens.

Limits are visibleQuotas, failed work, and operational state should not become silent footguns.
