The 18 new trampolining sites will be in the UK and across Europe, and the firm expects to create over 1,500 new jobs in the process.
It is aiming to increase turnover from the current turnover of £5m to in excess of £40m by 2020.
Established in 2013, AirHop currently operates sites in Guildford and Bristol – the latter facility is the world’s largest indoor trampoline park.
Darren Hedges, managing director of AirHop Ltd, said: “The confidence shown by the Santander team in the brand and its international growth potential, along with the flexibility of its Growth Capital financing product, was the critical factor in our choice of funding partner and we are very pleased to have found a bank that shares our vision.”
The £6m in Growth Capital funding from Santander Corporate & Commercial will be used to support the firm’s growth plans and initiate the development of key new sites.
Santander was supported by RSM and Foot Anstey with the management team at AirHop advised by BDO LLP.
