The events agency reported a £22m turnover in 2010, up from £18.6m last year. Its gross profit increased from £5.9m in 2009 to £10m for the year ending 31 December 2010.
Zibrant managing director sales and marketing Fay Sharpe said: "We have seen an increase in business from our existing client relationships as we demonstrate exceptional service delivery and value added, as well as some exciting new client wins."
In August 2010 Zibrant announced plans to add at least 20 new roles to its current 75-strong pharmaceutical events team, many of whom have moved from offices in Canterbury and Derby to Godalming.
Zibrant's managing director-operations Chris Parnham said: "Over the last few years we have taken Zibrant through tough economic times, into dramatic recovery, and now onto a new stable platform of strong leadership, clear strategic direction, and true customer service. We deliver total global solutions in an industry that now requires global partners.
"In today's market, clients need robust, far reaching, and creative solutions that only stable, successful and credible agencies like Zibrant are able to deliver."
Zibrant also revealed it plans to invest in technology and venture into complementary markets in 2011.
Motivcom recently reported a 22% increase in gross profit for 2010.
Zibrant's Fay Sharpe achieved the top spot in C&IT's Power 50, announced earlier this year.
