Hansen Technologies has all the makings of a company that's cut out to be resilient to a pandemic. But despite having a stable global customer base of telcos and utility companies, its slow organic growth has meant it has been overlooked by hungry tech investors.

The business, which has a market capitalisation of $640 million, provides billing, data management, customer care and catalogue software and services to companies including Energy Australia, Red Energy, Vodafone and South East Water.
