Sam Zou and James Bayly head the team at SubQuery, a decentralized data aggregation, indexing, and querying layer between Layer-1 blockchains and decentralized applications. SubQuery is focused on the fast-growing Polkadot ecosystem. 

Why you should listen:

The team had experienced first-hand the difficulties of testing, deploying, and managing blockchain infrastructure. The team founded OnFinality to solve key pain points around decentralized infrastructure management and automate the deployment of Polkadot/Substrate based networks to the cloud.

In 2020, while helping key Polkadot parachain teams, the team listened to requests for a data indexing service to help the teams better understand their chain data. Additionally, these teams wanted this in place to ease the barriers to entry for their future development communities. 

After a period of research, the team formally established the SubQuery project at the end of 2020 through a Web3 Grant, delivered the first open source version in January, and announced the platform to the world in February 2021. It now has backing from Arrington Capital and Digital Currency Group.
