About Tessara
About

Where the name
comes from.

tessera, tessarae
Latin - noun - plural
A small tile of stone, clay, or bone used in Roman mosaics. Also: a token of identity - broken in two and carried across cities and years, until the matching half proved the bond was real.

We chose the plural - Tessarae - because no identity stands alone. Every credential, every connection, every relationship is one tile in a larger mosaic.

We built Tessara because both professional and personal identity are broken. Titles are self-reported. Introductions go ignored. Online friends are strangers. The information to fix all of this already exists - we connected the dots.

The mark means something
One luminous diamond tile - four quadrants, one brightest. That tile is you. The others make the picture possible, but you are the one that stands out.

every tile is a relationship

2 - 2
Two verified agents - two social networks
One professional, one personal. Each with its own credential, graph, and network. Both grounded in the same verified person.
Day one
Valuable before anyone else joins
Built from your existing contacts and interests. No new behaviour required to get started.
Two Tessara - One person

You contain multiples.
Both versions are real.

The version of you at work - credentialed, accomplished, proven. The version of you everywhere else - curious, complex, alive. Tessara creates a verified agent for both. Then builds two social networks on top.
