Lucidworks (formerly known as Lucid Imagination) is a Redwood City, California-based enterprise search technology company offering commercial support, consulting, training and value-add software for open source Apache Lucene and Apache Solr. Lucidworks is a private company founded as Lucid Imagination in 2007 and publicly launched on January 26, 2009. The company was renamed to Lucidworks on August 8, 2012. The company received Series A funding from Granite Ventures and Walden International in Sept 2008; In-Q-Tel is a strategic investor. In August 2014, Lucidworks closed an $8 million dollar Series D round with Shasta Ventures, Granite Ventures and Walden International participating. The company follows a Professional Open Source model to target organizations evaluating or already using the Apache Lucene/Solr open source search platform for their search applications. The company also offers several free, certified distributions of Lucene and Solr, which include additional utilities, bug fixes, and performance enhancements. Apache Lucene and Solr originally established a following without commercial support; however, as the market adoption for commercially supported open source grows, enterprise search application developers have sought similar models for these applications as well.
