Three technology companies from the Charleston region got the call with several dozen other businesses to spend some time at the White House and with the president last week.

Dynepic, Teamphoria and Ohana Syndicate were all represented at Tuesday’s event, which the White House said it organized to “highlight the importance of investing in women and young entrepreneurs.” Among those in attendnace was President Barack Obama and investors from ABC’s “Shark Tank,” including Daymond John, Mark Cuban and Barbara Corcoran.

About 70 companies from around the country were at the ceremony.

James Island-based Dynepic was founded by Air Force Academy graduate Krissa Watry. It ties together technology and toys “moving play beyond two dimensions,” according to its website.

Teamphoria develops apps geared toward making employees engaged.

Ohana Syndicate has an app called Voyzik that lets someone stream music and listen to it with one person or multiple people, said founder Griffin Peddicord.

“It’s a great experience to meet entrepreneurs worldwide, rub shoulders and meet with (venture capitalists), the president, his staff, Mark Cuban and the Sharks,” Andrew Strickland, managing partner with Teamphoria, said via email.

Both Dynepic and Teamphoria went through the Harbor Entrepreneur Center’s accelerator program.

“Best part of the day is networking on a global level,” Watry said in an email.

The White House invitations show that what Charleston is doing for entrepreneurs “is working,” said John Osborne, co-founder of the center’s accelerator.

It’s not the first time a local tech representative has been invited to 1600 Pennsylvania Ave. Carolyn Finch, the woman behind Charleston Women in Tech, was there a few weeks ago for a “White House Tech Meetup,” according to a statement.

Another local company, Tarian Orthotics, also of the Harbor Entrepreneur Center’s accelerator program, was invited to last week’s ceremony. It was unable to attend because of a scheduling conflict, Osborne said.
