Polaris Partners led the $6 million investment round for Boxever, TechCrunch reported.

The financing, which would help expand the business for the Irish startup, was also participated in by Frontline Ventures, a Dublin-based firm. Proceeds from the latest round bring the Boxever's funding total to about $7 million, according to a report from Skift.

Boxever serves as a personalization platform catered towards carriers and travel operators through the use of big data. It seeks to provide a solution to the problem of big data that airlines face. It allows carriers to strengthen their marketing and personalization efforts because the service provides for "a single customer view." According to information from Boxever's website, the platform "creates a 360-degree view" of an airline's customers through data from online, offline and 3^rd party sources.

Airlines can then use Boxever to tailor-make how flights and other travel services are sold to customers. In doing so, airlines are able to provide enhanced customer experience and improve conversion, TechCrunch reported.

The report quoted Boxever Chief Executive Officer Dave O'Flanagan as saying, "Airlines have access to vast amounts of untapped structured and unstructured information about their guests and very few are using this effectively."

In order to provide this kind of service, Boxever evaluates the profiles of more than 60 million guests and look at "billions of individual shopping, purchase and support interactions." While it still has to contend with other rivals in the space, specifically the complex product suites that are produced by tech giants like IBM, Oracle and others, it is unique because it's a cloud-based platform that centers on the travel industry, the report said.

Together with the funding announcement, the Irish startup also said that it had struck a deal with Tigerair, a Singapore-based airline, to be their latest customer. Tigerair Group COO Alexander Knigge said the startup's platform helps "maximize up-sell and cross-sell opportunities," TechCrunch reported.
