The search intelligence platform secured Series B backing from Smedvig Capital and Panoramic Growth Equity to scale its product suite.
"This £8 million investment is a significant milestone for Captify as it will enable us to consolidate our position as the European market leader in search data driven advertising and analytics and put us on course to claim true global leadership. It is indicative of how the European ad tech space is flourishing and providing genuinely tough competition to established US rivals."
The Cambridge-based biotechnology company secured the capital from a group of angel investors and Finance Wales.
"The early support we have received for our ideas and technologies from our angel investors and from Finance Wales has been very encouraging. We are delighted that this will allow us to maintain the very rapid momentum we have achieved in a short time."
The job search engine raised capital from over 400 backers through the equity crowdfunding platform.
"We are proud of the world-class team and platform we have built at Adzuna, but we still have a long way to go in job search innovation, mobile apps and internationalisation."
Advisers B&Y facilitated the £500k capital injection and ownership buyout following a period of stagnant turnover.
"The project transformed from a requirement for working capital to a complete turnaround solution, and there was a significant level of interest from our investors from day one. I am delighted that in the end we found the right new set of shareholders, who bring with them enormous expertise in driving growth and profitability."
