StreamingFast
StreamingFast, founded in 2018 as dfuse and rebranded in Montreal by founders Alexandre Bourget, Mathieu Boulianne, Marc-Antoine Ross and Richard Reiner, provides high-performance blockchain indexing and streaming infrastructure. Its core technologies, Firehose and Substreams, let developers stream, transform and query chain data at low latency for real-time apps, explorers and analytics without running archival nodes. The platform supports Ethereum, Solana, Polygon and Antelope chains with gRPC streaming and parallel processing. Headquartered in Montreal with a distributed team across North America and Europe, StreamingFast powers indexing for major explorers, wallets and data providers handling significant event volume. The team emphasizes open-source stewardship and close collaboration with The Graph ecosystem. Expect an infrastructure-focused culture that values streaming reliability, data correctness and enabling developers to access accurate on-chain data quickly.
