Shortwave is an AI-native email client that upgrades an existing Gmail or Google Workspace account with a reimagined inbox, built by former members of Google's Inbox team and backed by Lightspeed Venture Partners. Its AI assistant drafts and triages email, its AI-powered search answers natural-language questions across your mailbox, and it connects to external tools as a Model Context Protocol (MCP) client — Shortwave consumes MCP tool calls rather than publishing a public developer REST API. Data is hosted on Google Cloud with AES-256 encryption at rest and TLS 1.2+ in transit, and the product undergoes annual CASA Tier 2 security audits, with SOC 2 Type II and GDPR compliance available on request.
