Lewis has four clients in Scandinavia, working for content management provider Tridian, software development tools firm Borland, wireless tech firm TDK Systems, and product distributor GE Access (in Denmark only).
Wigen has spent the past year on maternity leave.
Before that she worked for more than three years handling pan-Nordic media relations for Swedish tech agency Time PR.
'The Scandinavian tech market has been wobbly but there's now stabilisation,' said Wigen.
'The market began to pick up in mid-March and I think things will get better around the end of the summer,' she added.
