Held in central London, last year's Byte Night raised £250,000 for the various homelessness projects run by NCH throughout Britain.
The event attracted over 100 executives from Microsoft, Accenture, Vistorm, Palm and other leading hi-tech companies.
Guy Tarring, the marketing director at Vistorm, said: "The opportunity to get involved in something of this nature, which is both personally rewarding and delivers some much-needed support, doesn't come along very often
"I participated for the first time last year and immediately regretted the fact that I wasn't involved when the event was first started."
This year's event, to be held on Friday 21 September, has been expanded to include Manchester and Glasgow.
