Company profile
researched Aug 2026Fauna was a database company founded by former Twitter infrastructure engineers that built FaunaDB, a serverless, cloud-native operational database. The product stored data in JSON documents while retaining relational characteristics including strong consistency, joins, foreign keys and full schema enforcement, and exposed its own query language, FQL. It was offered as a managed service accessed over APIs, so that application developers did not provision, configure or operate database servers themselves.
The company positioned FaunaDB for what it termed a "client-serverless" application model — a successor to mainframe, client-server and three-tier web architectures — in which applications compose managed API services instead of running dedicated backend infrastructure. It ran on Amazon Web Services and Google Cloud, and in 2020 said it intended to add Microsoft Azure. Customers included development teams at Tyson Foods, Unilever, Lexmark and Anaplan.
In March 2025 the company announced it would shut down the Fauna service on May 30, 2025, stop accepting new customers, and transition existing customers off the platform, while committing to publish an open-source version of the core database technology and FQL.
Founding story
Fauna was started by two Twitter veterans: Evan Weaver, Twitter's former director of infrastructure and its 15th employee, and Matt Freels, the former technical lead on Twitter's database team, who became the company's chief architect. Weaver, who holds an M.S. in computer science and previously worked at CNET and SAP, drew on the experience of scaling Twitter's data infrastructure in building a cloud-first database. The company was remote from its founding while headquartered in San Francisco.
Business model
Fauna operated its database as a managed, multi-tenant cloud service rather than as software customers installed themselves, running on Amazon Web Services and Google Cloud with plans announced in 2020 to add Microsoft Azure. Customers were served through tiered plans — free, pay-as-you-go, Startup, Pro and Enterprise — with premium tiers receiving direct support and lower tiers directed to a community forum. The core database technology was proprietary, though the company shipped open-source drivers and CLI tooling and, at shutdown, committed to open-sourcing the core engine and FQL.
Subscription and usage-based pricing for the hosted database service across free, pay-as-you-go, Startup, Pro and Enterprise plans, with support levels tied to plan tier.
Traction
The company reported 25,000 developers worldwide using its serverless database, and its 2025 shutdown was described as affecting more than 195 databases and over 3,000 development teams. Named users included development teams at Tyson Foods, Unilever, Lexmark and Anaplan. Headcount was about 40 at the time of the 2020 funding round, when cumulative funding reached $57 million.
Latest developments
On March 24-25, 2025 Fauna announced it would sunset its database service, with full shutdown scheduled for May 30, 2025 at noon Pacific time, after which accounts and associated data would be permanently deleted. The company stopped accepting new customers, published migration tooling and a migration guide covering approaches such as JSON snapshot exports to AWS S3, and offered hands-on migration support to Startup, Pro and Enterprise customers while directing free and pay-as-you-go users to its community forum. Leadership attributed the decision to the capital intensity of running a global operational database service and the determination by its board and investors that the required capital could not be raised independently. The company said it would release an open-source version of its core database technology, including FQL, without giving a timeline.

Market position
Fauna competed in the operational database market against established and well-funded alternatives including MongoDB, CockroachDB, Microsoft Azure Cosmos DB, Amazon DynamoDB and Google Spanner. At its 2020 funding round it had raised $57 million in total and employed about 40 people; by its 2025 shutdown it reported 25,000 developers using the service and named enterprise development teams at Tyson Foods, Unilever, Lexmark and Anaplan as customers. Its closure was cited in industry commentary as an example of the difficulty and capital intensity of commercializing a new proprietary database as a service.
FaunaDB combined a document data model with relational capabilities — strong consistency, joins, foreign keys and full schema enforcement — delivered as a serverless, globally distributed managed service accessed via API. Madrona's S. Somasegar described the approach as distinct from MongoDB, CockroachDB, Azure Cosmos DB and Amazon DynamoDB, arguing that FaunaDB extended the serverless experience to the database layer. Commentators after the shutdown argued that the proprietary, closed-source model and limited cloud coverage constrained adoption relative to open-source distributed database alternatives.
Technology
FaunaDB is a distributed, serverless operational database that stores data as JSON documents while preserving relational features: strong consistency, joins, foreign keys and full schema enforcement. It provides low-latency global access to both relational and document data and is queried through the company's own language, FQL, with client drivers and a command-line interface. The service is cloud-native and multi-cloud, running on AWS and Google Cloud, and is consumed via API by serverless applications rather than provisioned as dedicated database servers.
Go-to-market
The company pursued a developer-led adoption strategy, appealing first to individual developers through a self-serve, free and pay-as-you-go service in order to build bottom-up adoption inside enterprises, an approach Madrona compared to MongoDB's path, in contrast to a purely top-down technical sales motion. Paid Startup, Pro and Enterprise tiers layered support and enterprise features on top.
Application developers building cloud and serverless applications, plus enterprise development teams; named customers included Tyson Foods, Unilever, Lexmark and Anaplan.
Geography
Headquartered in San Francisco and operating fully remotely since its founding; a later company description listed San Francisco and Boston. The service was delivered globally on Amazon Web Services and Google Cloud.
History
The company was founded in 2011 by Evan Weaver, former director of infrastructure at Twitter, and Matt Freels, former technical lead of Twitter's database team, who served as chief architect; a Forbes Technology Council profile gives the founding year as 2012. It operated remotely from the outset while maintaining a San Francisco base, later described as based in San Francisco and Boston. In July 2020 Madrona Venture Group led a $27 million investment, bringing total funding to $57 million; at the same time Eric Berg became CEO, Weaver moved to CTO, and Bob Muglia joined as executive chairman. Weaver left the company in 2023. In March 2025 the leadership team announced that Fauna would sunset its database service on May 30, 2025, citing the capital intensity of driving broad adoption of a globally operated database service and the board's and investors' conclusion that the necessary capital could not be raised independently.
Risks & controversies
The company shut down its service in 2025 after its board and investors concluded that the capital required to drive broad adoption of a globally run operational database could not be raised independently, requiring customers to migrate applications and data within roughly two months and resulting in permanent deletion of accounts and data thereafter. The announcement drew public criticism from users about the risks of depending on a single unprofitable vendor for critical infrastructure, and some developers reported that FaunaDB was cumbersome to develop against and cited defects such as errors when storing decimal values, prompting migrations to alternatives such as MongoDB. Observers also argued that the closed-source model limited adoption.
