A number of people working in the OpenPGP space are involved in the Sequoia project. Some work directly on Sequoia, some work on projects using Sequoia, some are otherwise working on improving the state of the OpenPGP ecosystem. Neal H. Walfield Neal began working on GnuPG towards the end of his PhD. After two and a half years at g10code, he joined p≡p in 2017 and co-founded the Sequoia project with Justus and Kai.
