Add two more to the list of Atlantic Canadian companies appearing at the Collision conference in Toronto next month.

Squiggle Park, the Halifax- and Toronto-based startup that helps to teach children to read, and Cape Breton app-maker Tapnbe will also attend what’s been called the fastest-growing tech event in North America. 

On Wednesday, we reported that Halifax companies Frogo, QRA Corp. and Side Door Access had been selected to attend the event. Squiggle Park Co-Founder Julia Rivard Dexter and the team at Tapnbe posted shortly afterward that their companies would be there as well.

Squiggle Park, which received funding last June from Indigo Books and Music CEO Heather Reisman, has launched apps with games that help children to read, which are now being used in several countries. Co-founded by Leah Skerry and Julia Rivard Dexter the company last autumn was accepted into the Rev accelerator at Communitech in Kitchener, Ont.

Cape Breton’s Tapnbe enhances smartphone engagement by placing digital interactive posters on smartphones, just as you would place paper posters on a wall. Its app for iOS and Android gives users timely information about such things as their position and what is near them. The company posted on Twitter that it will be exhibiting at Collision.  

Hosted by the Ireland-based Web Summit group, Collision brings together about 25,000 tech experts, companies and enthusiasts each year and has grown into the premiere tech event in Canada. It will be held this year at the Enercare Centre from May 20 to 23.
