LinkedIn Top Startups 2019: The 25 hottest UK companies to work for now

The 2019 LinkedIn Top Startups list reveals the 25 hottest companies where UK professionals want to work now.

With the 3rd annual Top Startups ranking, we uncover the young companies commanding professionals’ attention today: the ones that are growing massively, scrambling industries, shifting talent flows around the world and, often, altering how we work and live.

Our editors and data scientists parsed billions of actions generated by LinkedIn’s 645 million members – and looked at four pillars in particular: employee growth; jobseeker interest; member engagement with the company and its employees; and how well these startups pulled talent from our flagship LinkedIn Top Companies list. To be eligible, companies must be 7 years old or younger, have at least 50 employees, be privately held and headquartered in the UK. (You can learn more about our methodology at the bottom of this article.)

Methodology

LinkedIn measures startups based on four pillars: employment growth, engagement, job interest and attraction of top talent. Employment growth is measured as percentage headcount increase over one year, which must be a minimum of 15%. Engagement looks at non-employee views and follows of the company’s LinkedIn page, as well as how many non-employees are viewing employees at that startup. Job interest counts the rate at which people are viewing and applying to jobs at the company, including both paid and unpaid postings. Attraction of top talent measures how many employees the startup has recruited away from LinkedIn Top Companies, as a percentage of the startup’s total workforce. Data is normalized across all eligible startups. The methodology time frame is July 1, 2018 through June 30, 2019.

To be eligible, companies must be independent and privately held, have 50 or more employees, be 7 years old or younger and be headquartered in the country on whose list they appear. We exclude all staffing firms, think tanks, nonprofits, accelerators and government-owned entities.
