To celebrate Social Enterprise Day and raise awareness of the 70,000 social enterprises across the UK, last year we launched the #WhoKnew campaign.

The digital campaign was an opportunity for social enterprises across the UK to shout about the good work they're doing and the difference they're making in their communities and beyond. We invited social enterprises to tell their story with the #Whoknew hashtag and to post pictures on their social media feeds (including Twitter, Facebook and Instagram).

We also encourged people who love and buy from social enterprises to post pictures of their favourite social enterprise products or services on their social media feeds.

You can see lots of the pictures on Flickr.
