SimpleHash

SimpleHash operates as a data infrastructure provider for the blockchain industry, specializing in token and non-fungible token (NFT) data. The company was established in 2022 by Olly Wilson and Alex Kilkka and is headquartered in San Francisco. Wilson, serving as CEO, and Kilkka, the technical co-founder, brought relevant experience to the venture; Kilkka was previously the CTO at NFT social network Showtime, and Wilson was an Entrepreneur in Residence at Portage Ventures.

The firm's core business revolves around providing developers with a unified Application Programming Interface (API) to query complex, multi-chain blockchain data. SimpleHash indexes data across more than 80 blockchains, abstracting away the underlying complexity for developers. Its product suite includes REST APIs, webhooks for real-time notifications, and a Kafka streaming service for high-performance data access, covering everything from token metadata and pricing to NFT market activity. This service is designed to be integrated with just a few lines of code, significantly simplifying the development process for Web3 applications. The business targets other companies in the crypto space, including notable clients like Coinbase, Uniswap, Phantom, and Ledger.

SimpleHash operates on a Software-as-a-Service (SaaS) model, generating revenue through tiered pricing based on API usage. This structure provides a predictable income stream and caters to a range of clients, from individual developers to large enterprises requiring high-volume data access and service-level agreements. The company's value proposition lies in its ability to deliver reliable, comprehensive, and real-time data, including token prices, sales history, and media, while also offering features like AI-powered spam detection and automatic metadata updates. The company participated in the Winter 2022 batch of the Y Combinator accelerator, securing initial funding. In February 2025, the crypto wallet provider Phantom acquired SimpleHash for an undisclosed amount, integrating its team and technology to enhance Phantom's own data capabilities.
