The company also re-branded, launched its own events app and recruited new staff on its project team in 2014.
"We have had the most incredible year and considering where we were four years ago makes me realise what a fantastic team we have," said Penguins managing director Mark Buist.
"We have seen a marked increase from existing customers throughout all sectors. Many of our clients fully understand the benefits that live communications bring to their businesses and are keen to expand their events programmes," he added.
Buist revealed that he is now looking to grow the business over the next five years through a combination of new client relationships and potential acquisitions.
"We are excited by a variety of opportunities and look forward to growing our team to meet the increasing demand from both new and existing customers," he commented.
