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,[6][7] enterprise search application developers have sought similar models for these applications as well. Lucidworks is the primary commercial steward for the Solr project employing one-third of the project's committers and contributing 70% of the code in addition to producing the annual Lucene/Solr Revolution conference, most recently named Activate.[8]

The Lucidworks founding technical team consisted of Marc Krellenstein, a veteran in the enterprise search industry and several key contributors and committers to the Lucene project, Grant Ingersoll, Erik Hatcher, and Yonik Seeley, in addition to advisor Doug Cutting.
