Parity Technologies

Parity Technologies is a blockchain infrastructure company based in the United Kingdom, founded in 2015 by Gavin Wood and Jutta Steiner. The company builds core open-source software for decentralised networks, with a focus on scalability, security, and interoperability.

Parity is the primary engineering force behind Polkadot, a multichain protocol that enables independent blockchains to communicate and share security. The company also created Substrate, a modular framework that allows developers to build custom blockchains. Earlier contributions include a widely used Rust-based Ethereum client. The team operates as a remote-first organisation with approximately 200 engineers across four European hubs.

Parity serves blockchain developers, enterprises, and open-source contributors building on the Polkadot and Kusama networks. Its tooling and SDKs are used to create parachains, smart contract platforms, and application-specific blockchains.
