Tech Track 100

Customers including IHG and Betway use Thunderhead’s software to listen to customer activity. At the start of the pandemic, it says, some brands experienced a complete drop-off in activity, while others faced overwhelming demand. The company’s software allowed brands to change their marketing strategy, for example by using its “Audiences” feature to identify key workers and those who might need offline support. Chief executive Glen Manchester, 55, founded Thunderhead in 2001, and in 2016 sold the firm’s Smart Communications brand to Accel-KKR for $210m (£161m). Sales hit £7.6m in January this year, driven by its expansion into America.

Note: following publication, Fast Track recalculated Thunderhead’s CAGR as 178.16%
