Last week was BoulderBeta - the holiday edition - and it was an event not to be missed. A packed Absinthe House held a few hundred tech and startup enthusiasts, as well as 9 up-and-coming businesses. Toys (thanks to Sphero and Atoms) and treats (nearly every table had cookies, candy, cupcakes or cake balls) abounded as we wound our way around the room. 

Of particular interest to the Built In Denver crew were, of course, the digital startups. Here's a roundup of who we met - check them out! 

Roximity, a location-based advertising platform, enables retailers and brands to send targeted messaging to nearby customers. 

SlopeSquad has put together an app to help you track your ski days. Compare - and compete - with your friends. You can also unlock deals and check out local news.
