SonicJobs is an award-winning mobile app that is revolutionising the way people find and apply for jobs. Job search is broken. In 2019, only 4% of candidates that clicked on a job on mobile went on to complete the application. Employers are wasting budgets on clicks that don't convert, and candidates are wasting time. SonicJobs have built industry-changing Robotic Process Automation (RPA) and Chatbot technology that: 1. reads the employer's application process for each vacancy; 2. instead of redirecting the candidate asks the questions through a chatbot on the SonicJobs app; and 3. uses these responses to complete the application automatically. SonicJobs delivers a 23% click-to-apply conversion vs just 4% market average; a 6X increase in employer's ROI and candidate experience

A global style destination for kids, AlexandAlexa.com is the leading e-tailer that specialises in kids’ fashion, toys, school and homeware. Boasting a label stable of high fashion designers as well as fledgling boutique brands, AlexandAlexa.com offers parents a one-stop premium shop when shopping for babies all the way up to teens. Since launching in 2007, our relatively young company has fast become a pioneer in the designer childrenswear market. We have a naturally entrepreneurial workforce, which reflects in everything from our campaign photography to the way we handle our deliveries. The creation of our parenting broadsheet, The Lexem, and our pivotal role working with charity Kids Company to launch Global Kids Fashion Week has lead British Vogue to praise our ‘innovative marketing approach’. The AlexandAlexa culture is typically one that rewards hard work. Our work parties are infamous (in a good way) and we operate a flexible work time structure that helps everyone manage their work/ life balance better. We encourage departments to work closely together (our warehouse and our main office are a stone’s throw from one another) – it’s a cliché, but it’s a family business and we’re keen to maintain that mind-set, even as we’re expanding quickly. We look after our talent and strive to make this business a place where careers are shaped and friendships are formed.
