Celebrating 30 years of AIM

AIM - The London Stock Exchange's market for small and medium size growth companies

Welcome to AIM, which for 30 years, has proudly supported the lifeblood of the global economy – innovative companies.

AIM is the most active growth market in Europe, and over the last 5 years, 54% of all capital raised on European growth markets has been on AIM.​

Through 2025 we’re delighted to celebrate the 30th anniversary of AIM by recognising the individuals, organisations and policy makers who have contributed to AIM’s success. This success is embodied by the pioneering companies who have thrived by raising vital equity capital on AIM.

Since its inception in 1995, AIM has supported more than 4,000 companies to raise nearly £135 billion. The market has a committed base of investors and advisers including nominated advisors, brokers and market makers. This ecosystem has enabled SMEs from across the globe to gain access to the long term capital they need to grow.

“The London Stock Exchange is clearly committed to supporting companies at every stage of the funding journey. They partnered with us and helped us achieve our growth objectives – we had the right advisors and were given all the support we needed.”

This unique network of expertise is a vital part of the AIM community, who understand the needs of growing companies, and guide them through the IPO process and throughout their journey as a public company.

As AIM turns 30, we celebrate the success of companies past and present who have made such an important contribution to our economy.

Charting AIM’s positive economic impact

We recently commissioned a piece of research to understand the important role that AIM companies continue to play in driving economic prosperity.

The analysis, conducted by Grant Thornton, found that in 2023, AIM companies contributed £68 billion in Gross Value Added (GVA) to the UK economy and supported over 770,000 jobs.

Over the last 4 years the direct economic contribution made by AIM companies has grown by 6.6%, supporting economic activity through their supply chains and the expenditure of employees in their local economies.
