Cofounder & CTO, Zero Email Inc. Y Combinator X25. San Francisco.
I build agents that live where people already talk. As technical lead, I took one team through three products: Zero, an open-source AI email client; Orchid, a personal assistant in iMessage; and Keiki, the platform companies use to run customer-facing agents on iMessage, WhatsApp, SMS and more.

Work
Keiki (2026 - now)
Shopify for customer-facing agents. Companies launch agents that sell to and support their customers in the apps they already use for messaging.
- Led the platform architecture: one SDK and one API that run the same agent on iMessage, Apple Messages for Business, WhatsApp, SMS, Slack, Telegram, Teams, email and voice.
- Agents run on Keiki's cloud or on the customer's own servers from the same config, with an MCP server, OpenAPI spec, CLI, evals and tracing built in.
- Shipped Apple Pay inside Messages, Apple Messages for Business, and Agent2Agent (A2A) protocol support within two weeks.
- Customers in production include Veeza AI (2x channel revenue, 3x usage) and Vet Intel (1,000+ conference meetings briefed by text).
- $110K annual revenue, 37 paying customers, 2,588 messages per minute at peak, 10x usage lift for one customer.
Keiki Vault: Face ID approvals for AI agents
Before an agent sends an email, pays an invoice or runs any risky tool, Vault shows an approval card in the iMessage thread. Approve and Decline both require Face ID, each decision is signed with a key kept on the device, and Keiki verifies the signature before anything runs. Unlike a typed "yes", it can't be faked by a prompt injection or by someone holding the phone.
A personal assistant that lives in iMessage. It texts you your day, drafts replies, books meetings and handles the admin.
- Trained two in-house language models: one for personality and efficiency, and one for personalization.
- Built the iMessage agent infrastructure that later became Keiki, after businesses kept asking for what powered Orchid.
- The launch got 26M+ views, with signups peaking at 50 per minute.
- Named one of the top AI assistants on iMessage by Andreessen Horowitz partner Justine Moore.
- 25K users, 660K+ emails processed, 2.6M+ actions logged.
An open-source, AI-native email client that prioritizes, summarizes, drafts replies, and lets you chat with your inbox.
- Creator, engineer, and the repository's top contributor, with 1,410 commits (more than double the next contributor).
- Among the top 15 email repositories on GitHub, and in the top 0.001% of all GitHub projects.
- #1 Product of the Day and #2 Product of the Week on Product Hunt.
- The company's launch product at Y Combinator.
- 10.9K stars, 1.3K forks, 3,700+ commits.
