Micro
AI-native email and CRM client, backed by a16z. Seed-stage, about ten engineers. I built and owned the agent runtime.
- 250k+
- agent tool calls a month
- 6
- channels, one conversation
- 4
- model providers with failover
01Runtime
A Mastra multi-agent system serving 250,000+ tool calls a month, with model routing and failover across four providers.
02Channels
The same agent holds a conversation on Slack, iMessage, Telegram, email, LinkedIn, and X. I owned the routing and auth layer that makes that one agent instead of six.
03Memory
It remembers people, preferences, and past chats across threads instead of starting over each turn. Each user has a working store, and some facts persist across threads.
04Sandbox
A cloud coding sandbox where a coding agent writes, runs, and previews full-stack apps and publishes them as live sites. Long builds run on durable jobs that outlive the request.
05Graph
Prism is a typed object graph over Postgres. I extended it so the agent can walk CRM relationships, and built HubSpot and Attio import that avoids duplicates.
