The Crew

    • Brett
    • Brett Martin CEO / Water Boy
    • Brett is the Co-Founder and CEO of Sonar. Prior to founding sonar, Brett conceived of and built game-changing mobile technology companies as the Director of K2 Media in NYC. Prior to K2, he and a college friend moved to Austin, taught themselves how to code, and built the Data Owl, the world’s first automated social media monitoring service for small businesses. Before that, he researched start-ups as a Fulbright Fellow in Milano, Italia.

      In his previous lives, Brett has worked at VBS.tv as an Internet marketing associate and on Wall Street as an equity research associate. Other things he is proud of include getting published by Harvard Business, founding a rock band, starting a non-profit, earning a B.A. in economics from Dartmouth College, and sailing thousands of miles from Maine to Dominica in a 30ft ketch. Hit him up if he can be of assistance.

    • Brent
    • Brent Hargrave Co-Founder
    • Brent co-founded and leads tech development at Sonar. He digs live music and pens pithy bios.

    • Wynne
    • Wynne Chan Creative Director / Design Monster
    • Wynne is one happy soul designing your Sonar experience. She started experimenting with web design on her first Gateway computer in 1994. Wynne would like Brett to teach her how to surf; she is lobbying to move Sonar Intergalactic HQ to Hawaii.

    • Katie
    • Katie Smith-Adair VP of Voice / VP of Fun
    • Katie is a Portland, OR-transplant, taking over New York, with an affinity for owls, puns and portmanteaus. Coming from a background in technology PR, Katie has a few startup flings and affairs under her belt, but is happy to be settled down with her true love now. She is in charge of making Sonar famous.

    • Paul
    • Paul Tepper Fisher CTO
    • Fueled almost exclusively by cereal and Hummus Kitchen, Paul runs Sonar’s engineering—a real tight ship. Prior to Sonar, Paul was CTO at both K2 Media Labs and MarketSharing, served as Director of Engineering at Lime Wire, helped win Webby awards for Wired.com while leading the technology teams there, founded two companies, co-wrote two technology books and received his B.A and Masters degree from Johns Hopkins University. He’s a real underachiever.

    • Ben
    • Ben Kempe VP of Engineering / German Pastries Advocate
    • Prior to Sonar, Ben was Senior Architect/Team Lead at K2 Media Labs and worked as Software Architect at Lime Wire, creating a world-class music service. Previously, he built high-performance trading systems at Accenture and worked in AI research for DFKI. He received his MS in Computer Science from Saarland University and is Sonar’s resident piano-playing manatee fan.

    • Roger
    • Roger Chang Code Monkey
    • Roger recently jumped aboard the social bandwagon and discovered the vast world of knowledge to be had. He is not to be bothered when he is "in the zone", coding away. People often confuse him for his twin brother who also codes for a living, but when asked, he is the better-looking one of course!

    • Ximena
    • Ximena Vengoechea Product Marketing / Community Lovebug
    • Ximena (say hee-men-ah) is a natural social butterfly with a penchant for adventure & a love of people. She works building Sonar's glorious community & spreading Sonar magic. Pre-Sonar, Ximena studied at a small Massachusetts school named Harvard before moving to Paris to work in the art world. She remains an avid gallery hopper & a supernerd about all things #artstech.
