NoSQL database software provider MongoDB has appointed Dev Ittycheria as CEO, replacing current boss Max Schireson.

Ittycheria joins from his role as managing director of capital firm OpenView Venture Partners, having previously served as CEO of BladeLogic, an automation software firm bought by BMC for $800 million (£475m) in 2008.

Schireson will remain at MongoDB after officially handing over on 3 September, when he will take up the role of vice-chairman.

The move comes as rumours mount that the software firm, which received $150 million (£89m) in a funding round last October, could be preparing for an IPO this year.

MongoDB's NoSQL software is the most widely used among a number of start-up companies offering non-relational databases, including CouchDB, Cassandra and Couchbase.

It is the fifth most popular database system in the world, and has been deployed by a range of enterprise firms, including eBay, Forbes and Microsoft, as businesses seek ways to deal with growing data volumes.

Last week, the vendor also announced that it has poached a key engineer from rival Oracle, Roger Bamford, to lead development of its open source software.
