What StreamingFast does
StreamingFast is a Montreal-based blockchain data infrastructure company founded in 2018 (originally as dfuse) that builds the open-source Firehose and Substreams technologies for high-throughput blockchain data extraction and transformation. Firehose is a files-based, streaming-first extraction layer that ingests full blockchain history into flat files and pushes blocks in real time with a cursor that handles forks and reorganizations; Substreams is a parallelized, Rust-based transformation engine that sits atop Firehose and allows developers to compose modules permissionlessly and sink data to PostgreSQL, MongoDB, Kafka, PubSub, subgraphs, Google Sheets, and other destinations. The platform supports 15+ chains including Ethereum, Solana, Polygon, Arbitrum, Optimism, Avalanche, NEAR, Bitcoin, Base, Starknet, and Sei, and is positioned as the data backbone for The Graph Network under a $60M core developer grant awarded in June 2021.
The company operates a hybrid go-to-market combining an API-first self-serve funnel (thegraph.market, app.streamingfast.io) targeting blockchain developers, an enterprise field-sales motion through the Firehose Integration Program that sells professional integration, hosting, and maintenance services to protocol teams, and managed hosting for Firehose/Substreams clusters. Revenue streams are split across subscription/freemium API services, professional services billed via custom proposals, and managed services. Customers span blockchain analytics firms (Messari, Amberdata, TopLedger, DappLooker), enterprise protocols (The Graph, Decentraland), and developer startups (Aleno, Airstack, Propeller Heads).
In 2021 StreamingFast rebranded from dfuse, transitioned to a fully employee-owned structure, and deepened its role in the web3 ecosystem via strategic investments in Aptos Labs, Ceramic, Fluence Labs, and Lighthouse Labs, plus a joint venture with Diagram Ventures called Boolean Labs. The firm is led by co-founder and CEO Mathieu Boulianne and co-founder and CTO Alexandre Bourget, with operational infrastructure relying on Google Cloud, OVHcloud, Auth0, and Stripe.

StreamingFast product offering
Product offeringCore offering
StreamingFast builds and operates open-source blockchain data infrastructure composed of two flagship technologies: Firehose, a flat-file streaming-first extraction layer that pulls full blockchain history at high speeds, and Substreams, a parallelized Rust-based transformation engine that lets developers compose modules and sink data to PostgreSQL, MongoDB, Kafka, Google Cloud PubSub, subgraphs, flat files, or Google Sheets. The company sells API access (freemium/paid), managed hosting, and professional integration services for blockchain protocol teams, and it operates as a core developer on The Graph Network supporting 15+ chains.
Product overview
StreamingFast offers a platform-plus-modules architecture centered on two flagship open-source products: Firehose and Substreams. Firehose is the core data extraction layer that collects blockchain history into flat files and streams data in real-time using a push-first model. Substreams is the parallelized transformation engine built on top of Firehose, enabling developers to write Rust modules, compose upon community modules, and sink data to any destination. The platform also includes supporting modules like Index Modules for performance optimization, RPC Poller for faster chain integration, and various sink integrations (PostgreSQL, MongoDB, Kafka, etc.). As a core developer on The Graph, StreamingFast integrates its technology across all major blockchains including Ethereum, Solana, NEAR, and many EVM-compatible chains.

Products and services
- Substreams A blockchain-agnostic, parallelized and streaming-first engine that serves as a blockchain data transformation layer. Powered by Firehose, it enables developers to write Rust modules, build upon community modules, and sink data anywhere (PostgreSQL, MongoDB, Kafka, subgraphs, flat files, Google Sheets). For blockchain developers, data analysts, and indexers building on supported chains.
- Firehose A blockchain data extraction layer designed from scratch to process the full history of blockchains at unprecedented speeds. It uses a files-based and streaming-first approach, extracting blockchain data into flat files and pushing block data in real-time, with built-in fork/reorg handling and 99.99%+ high availability. It is the foundation layer underlying Substreams.
- Firehose Integration Program Professional service for integrating new blockchain networks with Firehose and Substreams, including implementation, managed hosting, maintenance, and optional The Graph Network integration. Delivered on a 4-8 week timeline with a 99.99%+ uptime guarantee and custom-priced proposals. Targeted at blockchain protocol teams.
- Substreams Registry Open community repository at substreams.dev for discovering, building, deploying, and sharing Substreams modules, with GRT rewards for contributors. Updated in December 2024 to support publishing and module reuse across the Substreams ecosystem.

StreamingFast competitors and assessment
Company assessmentBroad incumbents
- Alchemy: A larger, well-capitalized blockchain developer platform offering RPC, indexing, and data APIs. Alchemy competes with StreamingFast in serving Web3 developers, particularly through its broader product portfolio spanning node infrastructure and enhanced APIs.
- Infura: ConsenSys-owned blockchain infrastructure provider offering RPC endpoints and developer tools. Competes with StreamingFast's Firehose/Substreams for developer adoption, particularly for Ethereum and EVM chain data access.
- QuickNode: Blockchain infrastructure platform offering RPC, indexing, and developer APIs across multiple chains. Targets similar developer personas as StreamingFast with self-serve API access and marketplace positioning.
- Chainstack: Managed blockchain node infrastructure and API platform supporting multiple protocols. Competes with StreamingFast's managed hosting and RPC infrastructure offerings for protocol teams and developers.
Direct peers
- The Graph: The decentralized indexing protocol for which StreamingFast serves as a core developer. Both operate in blockchain data indexing, and StreamingFast's Substreams powers Substreams-powered subgraphs on The Graph Network, making them deeply intertwined ecosystem partners and direct competitors in the indexing category.
- Covalent: Provides a unified blockchain data API across multiple chains, directly competing with StreamingFast's API services. Both target developers building applications that need structured, queryable on-chain data and offer freemium/self-serve pricing models.
- Bitquery: Blockchain data API provider offering GraphQL APIs across multiple chains for both on-chain and DEX data. Directly competes with StreamingFast's Substreams API for developer data consumption use cases.
Emerging players
- Dune Analytics: Web3 analytics platform with a SQL-based query engine over blockchain data. While more focused on analyst-led queries than raw data infrastructure, Dune is referenced in StreamingFast's own positioning as a proprietary alternative whose vendor lock-in Firehose/Substreams is differentiated against.
- Pocket Network: Decentralized RPC infrastructure protocol for blockchain applications. Overlaps with StreamingFast's node-side infrastructure layer and competes for developer workloads requiring reliable RPC and data access.
- Goldsky: Real-time blockchain data pipelines and APIs, including subgraphs and custom indexers. Directly comparable to StreamingFast's Substreams-based transformation and sink model, targeting Web3 builders needing production-grade data infrastructure.
