Show HN: Era – Complete Simulated Companies for Your Agents

Era generates complete, live simulated companies your agents can connect to and run against: full SaaS stacks (Salesforce, HubSpot, Zendesk, Gong, Jira, Confluence, Slack, SharePoint, Google Drive, Box, Dropbox, AWS, etc.) served over vendor-native REST and an MCP layer. It creates a single coherent tenant with one identity replicated across every system, accessible via a web console or a CLI and usable in CI with published Docker images. The intent is explicit - replace brittle mocks with realistic, runnable estates for development and benchmarking of agents and integrations - while noting synthetic environments are not a substitute for staging with real sensitive data. Free for builders and sized to emulate enterprise scale.

The generator builds substance, not noise: timestamps follow employees’ work hours and timezones, personnel have life histories (hires, promos, transfers, leaves), deal sizes and customer headcounts follow published statistical shapes (e.g., median deal ~$17k, median customer headcount ~180), and multi-account incidents produce realistic ticket bursts. File stores, transcripts, chats and tabular systems all project the same graph; a top-tier tenant can include tens of thousands of contacts/files/calls/tickets (examples: ~18.8k contacts, ~15.8k files, ~13.7k calls, ~12k tickets) and thousands of hours of audio. “Mess” (duplicates, junk rows) is injected deliberately, declared in a manifest and capped (30% per column), and extensive data-fidelity checks and published detector results distinguish it from naive synthetic data.
