San Francisco: Start-up Breather offers innovative rooms for meetings in places including Montreal, New York and San Francisco. A Scandinavian-style loft in the Yerba Buena neighborhood starts at $25 per hour. All properties come equipped with Wi-Fi and can be rented by the hour.
Boston: District Hall, the city’s innovative tech space, allows anyone to come hang out for a meeting without prior reservations. A local coffee bar and dry-erase boards covering some walls make it easy to have a caffeine-fueled brainstorming session.
New York: Grind, a co-working community with three New York locations, allows members to settle down away from the crowd for $40 per day or a discounted monthly fee. For a last-minute meeting, visitors can book a soundproof conference room that fits up to eight people for $75 per hour.
Chicago: Catalyst Ranch, a 15,000-square-foot meeting venue in the city’s West Loop, can feel more like a carnival than a meeting space. Rooms of all sizes mimic a Mexican hacienda style with colorful seating, vintage rugs and artwork from around the world. Prices are $92 per participant for a full-day meeting.
Los Angeles: Space Abbot Kinney, a penthouse for meetings in Venice, Calif., has flexible rooms, an outdoor deck, a private VIP entrance and a glass atrium lounge. There’s gallery lighting rather than harsh office lighting, so meetings take on a decidedly less corporate feel. Rental rates start at $500.
