The company behind the Web Summit has announced plans to hire an additional 40 people at its Dublin headquarters over the next six months.

The new roles are in addition to the 40 jobs announced three months ago and are across a range of areas including engineering and sales.

Web Summit said the expansion was part of its international growth plans, with the company also looking to hire staff in San Francisco and Hong Kong.

Announcing the new roles in Dublin this morning, Web Summit said it had taken far less time than expected to fill the jobs announced in April and it was impressed by the talent available.

Web Summit CEO Paddy Cosgrave has also announced that a number of political figures, including Al Gore and Francois Hollande, would be speaking at this year's main Web Summit event in Lisbon.

Separately, eCommerce Intelligence firm Clavis Insight is to more than double its presence in China, by adding 25 new jobs at its Shanghai.

Clavis already has 20 people based there.

The new jobs will be across sales, marketing, professional services and operations.

Clavis’ Shanghai office supports its customers across the Asia-Pacific region.
