Irish firm Cleverbug has raised €4.4 million in funding, clearing the way for the company to expand its operations further.

The company will use the cash to build on its current services, which include social gifting and personalised printed cards. Customers can create the cards and send them anywhere in the world. The service uses algorithms that use Facebook connections to offer a personalised gallery of cards and designs that are based on social relationships and user behaviours.

The latest round of funding was led by Delta Partners and brings to €6 million the total amount raised by the company to date.

"We are very impressed with the outstanding work by the Cleverbug team in bringing a much-loved product to the market, and the overall red-hot social gifting category," said Maurice Roche of Delta Partners.

Chief executive Kealan Lennon said the investment was a vote of confidence in the firm.

“It’s a good opportunity,” he said. “They’re getting into a space that covers ecommerce, mobile and social. And it’s a real-world product, it’s tangible. It ticks a lot of boxes. “

The company already has plans to add to its staff numbers, with 25 jobs promised in the coming year. The majority of these jobs will be in Ireland, with some in the US Kealan Lennon said.

Cleverbug is already exploring opportunities for partnerships with companies that have a user base but want to monetise it.
