I've followed GeoVation since it started, and have been involved in a few projects which gained funding, notably our early Mission:Explore projects.
The hub opened recently as a venue for meetings and projects to take place in London, and I've attended several events with Chris Parker and colleagues, including the initial launch at the Royal Society of Arts.
An e-mail from GeoVation  alerted me to the launch of OS Open Names, which has an API and looks like it might be of some use with a little investigation.

The latest GeoVation challenge will be launched shortly...
