Portrait of Bo Fishback, CEO of Zaarly, at 1369 Coffee House in Central Square in Cambridge, Mass., on 13 April 2011.  ..Zaarly is a startup founded in mid-February 2011 and intended to launch May 10, 2011.  Fishback calls the company &quot;a proximity based, real-time buyer powered market,&quot; and it will allow users to advertise what they need, at what price they are willing to pay, and in what timeframe they need it.  The service will allow the exchange of goods, services, and experiences.  The company raised $1 million in the first 48 hours after pitching the idea at a technology conference.  Fishback traveled to Cambridge to meet with potential investors, marketing partners, and get introductions to influential people in the Boston-area startup and entrepreneurship communities...CREDIT: M.
