The company is classified as a data-privacy technology provider selling recurring SaaS to consumers, with global geographic exposure.

▸Full profile — market position, technology, go-to-market, geography, history
Market position
A pre-seed, privately held company in the consumer data-privacy software category, positioned alongside other online identity-masking and alias services such as Phantom LogIn, Mask.it, Invisit, and Cloaked.
The approach is built around issuing a distinct alias per website rather than a single shared identity, so that personal identifiers are never exposed to the sites a user interacts with and cannot be correlated across them.
Technology
Alias-generation technology that creates per-site identities, email masks, and phone aliases used in place of a user's real contact details.
Go-to-market
Individual consumers seeking greater privacy and security in their online interactions.
Geography
Headquartered in Detroit, Michigan, United States, with global geographic exposure.
