Database firm Basho says a $25m funding injection will help it step up development efforts for its Riak distributed NoSQL key-value data store.
The series G funding round, led by existing investor Georgetown Partners, will also enable the company to expand marketing efforts.
The database, which Basho created and continues to develop as an open-source project, notched up a significant increase in enterprise adoption in 2014, according to Basho, and has now been deployed by more than 30 percent of the Fortune 50.
The company said it has recorded Riak deployments in industries including advertising, financial services, gaming, retail, and healthcare, where it replaced Oracle as the database behind a national patient database system for the UK's health service.
The National Health Service announced it had migrated to a Riak Enterprise-based Spine 2 patient record platform, which is being used by 21,000 organisations.
With the launch of Riak Enterprise 2.0 in September, the company replaced Riak search with the Apache Solr engine, a move designed to allow integration with a wider range of external software through APIs.
Riak Enterprise 2.0 also introduced authorisation and authentication for the first time, so that a user's or group of users' identities and permissions can be verified before gaining access to the database.
In a bid to widen the database's appeal and adoption in new use cases, Basho also introduced extra data types in the enterprise-supported version of the database to include sets, registers, flags, and maps, which are designed to simplify application development.
Last August, the company shipped its Riak CS 1.5 cloud storage software, which it said is being used together with Riak for critical web, mobile, and social applications, and public and private clouds.
