Brandon Leitner and Rick Lowe of Cresa Boston represented Provenir, a company that develops and markets enterprise software solutions, in a 3,180 s/f new office lease at 320 Congress St. Provenir is now occupying a portion of the second floor of the seven-story, 54,299 s/f office building. The landlord, Congress Plaza LLC, was represented by Jeff Becker of NAI Hunneman. Provenir is a pioneer in proactive customer listening and engagement software. The company's offerings enable customer-focused businesses to rise to the challenge of big data by proactively listening and engaging with individual customers, across all channels in real-time. According to Leitner, the growing company wanted to be in the city's hottest submarket-the Innovation District.
