01 / WHAT IT BUILT
What the company did
Blyss was a privacy-infrastructure startup founded in 2023 by Samir and Neil and backed by Y Combinator's Winter 2023 batch. It offered homomorphic encryption as a service through blyss.dev: an open-source SDK and fully managed developer API for private retrieval from key-value stores. The technology let servers compute on encrypted data - for example checking passwords against breach databases or resolving domain names - without ever learning what users were doing, giving even small developers privacy guarantees previously only available to big tech companies.
