Kieon, a London-headquartered web and mobile app development business with an offshore facility in Bangalore, India, was acquired for a total cash consideration of £700,000, of which £200,000 is deferred and payable over the next two years.

Meanwhile, Glasgow-based Yomego, which offers social media strategy, measurement and insight services, was acquired for a cash consideration of £380,000. Yomego has a turnover of around £700,000, while Kieon generates revenues of around £900,000 a year.

Communisis chief executive Andy Blundell said: "We're expanding our reach upstream and into new channels. There's a lot of interest in online and mobile now and while we have some online capability, we're growing that with the Kieon acquisition.

"The Yomego deal is in response to a lot of interest in social media from most of the companies we talk to - there's a lot of hesitancy about how to engage with social media affectively and having made initiatives how to then measure and improve them.

"It's particularly in that area that Yomego are very strong."

Kieon employs a small London-based front end and leadership team headed up by co-founder Gwilym Lewis and also has around 50 development staff working at its offshore facility under co-founder Smita Malipatil; Yomego employs around 15 staff in Glasgow under managing director Steve Richards.

Kieon will report into Communisis' creative business and Yomego will report into the firm's data business.

Commenting on the increasing importance of social media as part of an integrated marketing communications strategy, Blundell said: "A lot of companies are feeling like they ought to be involved but are rather unsure about how to do it and equally how to measure it.

"We can now take our customers through that process: we can design campaigns; advise what to do and what not to do; and moreover as that investment ramps up we can measure the effectiveness of that and supply results back, in terms of ROI, that are as factual as they already are in other media."

Central to the latter element will be Yomego's proprietary Social Media Reputation (SMR) service, which provides comprehensive tracking from 29,000 social spaces using Alterian's Social Media Monitoring tool (SM2). This gives customers a benchmark score out of 100 that equates to customer satisfaction, as well as daily alerts and monthly insight reports, amongst other services.

Blundell added that the company was keen on making the right acquisitions to complement its organic growth and said that Communisis would continue to focus on organic growth allied with selective M&A activity in creative content, data, digital marketing and social media.

On the technology front, the £10m installation in Liverpool of the firm's two T400 high-speed colour digital presses was said to be progressing on schedule, with the first running live jobs since February and the second due to be fully operational in June.

Blundell, who will fly to Dusseldorf tonight (2 May) to take part in an HP presentation at Drupa, said that the company was "interested in development on the front end and the high-speed colour side".

"We've got a number of people going to the show," he added.
