Top 20 UK startups list 2023

The last year has presented numerous challenges for businesses in various sectors, including persistent inflation and a fluctuating job market.

Startups, too, have faced their share of difficulties, particularly in securing venture capital funding. In the UK, late-stage funding for startups witnessed a 75% decline in the first half of 2023 compared to the same period in 2022.

However, challenging times often spur adaptation and innovation, opening doors for new industries. For instance, artificial intelligence startups are experiencing a significant increase in capital, raising 66% more on average than in 2021. Additionally, data from LinkedIn indicates a more rapid growth in green entrepreneurship compared to entrepreneurship in general.

The seventh annual LinkedIn Top Startups list celebrates this spirit of innovation, spotlighting 20 UK companies that have demonstrated rapid growth and garnered attention. These startups have navigated recent economic and workplace challenges, distinguishing themselves to investors and top talent.

To curate this list, LinkedIn analysed data focusing on four key areas: employee growth, jobseeker interest, member engagement with the company and its employees, and the company's ability to attract talent. This year, LinkedIn has modified its criteria, reducing the age limit to five years or younger, allowing it to include more companies in the initial stages of growth.

LinkedIn's evaluation of startups hinges on four critical pillars: employment growth, engagement, job interest, and the ability to attract top talent. The process for measuring these pillars is precise and comprehensive.

Employment growth: this is assessed by the increase in employee numbers within the designated methodology time frame, requiring at least a 10% rise in headcount.

Engagement: this metric gauges the level of interaction with the company's LinkedIn page by non-employees, including views and follows, as well as the frequency of non-employees viewing profiles of the startup's employees.

Job interest: LinkedIn tracks the rate at which job positions, both paid and unpaid, at the company are viewed and applied for. This serves as an indicator of the startup's appeal in the job market.

Attraction of top talent: this measures the startup's success in recruiting employees from any global LinkedIn Top Company, expressed as a percentage of the startup's total workforce.

All data is normalised across eligible startups to ensure fair comparison. The methodology time frame spans from July 1, 2022, through June 30, 2023.

For a company to qualify, it must meet certain criteria: it should be fully independent, privately held, employ 50 or more full-time workers, be five years old or younger, and have its headquarters in the country of the respective list. Exclusions apply to staffing firms, think tanks, venture capital and law firms, management and IT consulting firms, nonprofits and philanthropy, accelerators, and government-owned entities. Furthermore, startups that have announced layoffs of 10% or more of their workforce, as corroborated by corporate announcements or reliable public sources during the specified time frame, are deemed ineligible. These decisions are made by the LinkedIn News team, drawing on company statements and credible news reports.
