A new way to socialize in real life.
Callback is a VC funded early-stage startup based in Tokyo, founded in the Spring of 2021 by Harvard and Stanford alumni.
Callback is a new way to socialize in real life. It lets you express who you are, connect with others, verify membership, and distribute special tokens (coming soon), all with just a tap. Concretely, the Callback mobile app currently allows users to create web profiles with an image and info and purchase stickers linking to their profiles for themselves or others. It supports Web3 by having profile NFT verification and has a feature for venues to verify NFT ownership for entrants. In the future, Callback will be more Web3 focused, with features such as distributing tokens from stickers and creating a Proof-of-Meetup protocol. Callback’s mission is to be the primary, secure bridge between the physical and Web3 worlds.
