We started as a silly lifestyle app for teenagers wanting to send simple hand signs. Everything changed with feedback from the Deaf community.

That’s why now we are building the first messenger that uses the full power of sign language, to help over 70 million people who use sign  language day to day, and reach over 360 million who are deaf or hard of hearing.
