Definition
Founders and executives use sift.mx as an attention layer: whitelist the company and key relationships, require a cover from everyone else.
Reachable, not interruptible by default
Going dark loses deals. An open personal inbox loses days. A sift handle keeps a public path open while making unsolicited access costly.
Domain and contact allowlists
Whitelist your company domain, board, counsel, and recurring investors so internal and known traffic never hits a paywall.
Signal from strangers
A paid cover is a crude but useful filter: recruiters, vendors, and cold “quick chats” either value the ask enough to pay or they do not belong on your critical path.
