Encino-based market research software developer United Sample has changed its name to uSamp as part of rebranding campaign. The new name reflects client-centric technology and the global sample delivered through its surveys, company officials said. uSamp develops market-research software and provides online surveying and panel-recruitment tools. “The Internet has made it easier than ever to assemble a group of people to take surveys, but that ease can be misleading if measures to ensure quality aren’t in place,” said Matt Dusig, co-founder and CEO of uSamp.
