Read the full description
Skein is business email on your own domain with an AI agent built in. Most email stores your conversations and leaves the remembering to you. Skein keeps them moving: it notices when an investor, customer or candidate goes quiet, drafts the follow-up in your tone, holds a meeting slot and asks you in Slack, WhatsApp or on your phone before it sends. Every morning, a short brief of what needs you. One product, not an assistant bolted onto another inbox. Hosted in the EU.

Partial The AI follow-up agent and calendar/UI layer are vibe-codeable, but a real business email product needs reliable mail servers, deliverability (SPF/DKIM/DMARC, IP reputation), spam filtering and abuse handling that are hard to get right.
What it would actually take: The agent part can be built on LLM APIs with Gmail/Outlook/calendar integrations, but hosting a domain-based mailbox service means running or integrating SMTP/IMAP infrastructure with warmed sending IPs and deliverability monitoring. That requires email-infrastructure engineering expertise and ongoing operations, often bought from an existing provider such as a transactional mail API or a hosted mail backend.
