Our Philosophy

Entrepreneurship can be lonely - and it can be hard. We believe that entrepreneurs working in a community of creative individuals learn more, grow faster, and build better businesses. We provide an environment that supports great entrepreneurs. We strive to build a community of diverse residents and to create a fun space that promotes innovation.


The power of Community


C3 is for startups, freelancers, small businesses, and entrepreneurs who want the "power of community" to work for them. Located in the heart of Kendall square, C3 is a place where the entrepreneurial vibe is strong, professional, and supportive. We provide an affordable place to work, to meet colleagues, and to get to know other like-minded professionals in the Boston/Cambridge area.



With plenty of natural light and an open, airy layout, the C3 space feels like home from the moment you begin working. Both a quiet space and phone area are designated to make sure you're able to find a space that supports your work, and there are plenty of flexible places to set up throughout the center.


The C3 space features fast and reliable internet, access to 50+ conference rooms, 20+ phonebooths, and several printers, copiers, and scanners. We also have a workbench with a 3D printer available for community use. All of the tools you need to get your work done are here - just bring your computer and get started!



The coworking space is equipped with highly adjustable Aeron chairs and a variety of standing and seated desks to suit your needs. You can even reserve the treadmill desk! Shelves throughout the space provide overnight storage for C3 members, and soft seating options are scattered throughout the space.


C3 is part of CIC Cambridge. our members have access to amenities across all CIC locations in Cambridge, Boston, St. Louis, Rotterdam, Miami, and beyond.

CIC creates powerful innovation communities for exceptional entrepreneurs who fix the world. Home to more startups than anywhere else in the world, we house 1,000+ companies throughout our Greater Boston area locations. The model at CIC promotes growth - as your company's needs change, your office can be adapted to follow suit.
