Hey, great site, and thanks for the listings!
Just want to provide an update: we have a Geek Pass for $100, use 25 hours whenever you want. Still free Peet’s Coffee, and we have showers too. Come in and spend a free day!

PopSignal Discussion: The Surge in Boston’s Entrepreneurial Ecosystem – Part 1 of 2 // May 4, 2010 at 4:02 pm
[...] A few years ago, it was pretty much only BetaHouse and the CIC for tech shared spaces. Now DogPatch Labs is expanding, Bocoup Lofts is opening up, new ones are popping up, and people are even thinking about models to support free office space (see a full list of coworking spaces in Boston) [...]
Hello Boston,
You’ve got a good list going for shared office space options. Here is one more to consider adding to your list. Check out http://SharedBusinessSpace.com.
Cheers!

no pun intended
You might want to include greenstreetspace in your listings. Located at 359 Green Street, Cambridge, it is a well-located shared-office co-working environment.
Thanks for putting this list together! Just an FYI: Cambridge Coworking Center at CIC is now located on the even more-light-filled (and newly built out) space on the 3rd floor. Come check it out!
Hey there,
We have a new shared workspace you might be interested in.

I’m writing from Boston World Partnerships. We’ve got a great new initiative going on, aiming to hook up startups with work space. The website is called GrabADesk.com – check it out if you’re looking to make that connection!
Great list! There’s a new coworking space opening soon right on Newbury Street called Oficio.
I’ve worked with a few coworking spaces in Boston but Oficio has lower and more flexible prices that are especially aimed towards freelancers and self-employed professionals.
Their website is live at: http://myoficio.com.

[...] Seven different places to choose from in the Boston & Cambridge areas. [...]
Hey Popsignal! Geek Offices has two offices: 1) 14,000 square feet in Inman Square, Cambridge with over 20 companies and 65 members and 2) 11,000 square feet in North Newton with over 10 companies and 25 members. Both spaces have the most affordable and flexible monthly arrangements for offices, cubicles and worktables around. Both with free coffee and free internet. Our Geek Company plan allows a company of 5 to pay only $800 all in! Newton has free parking for monthly members. See more at our website.
Beta House has apparently been closed since 2010. Probably about time to remove them from the list.
Green Street Places has been closed since 2011 as well.
And for those folks who live west of Rt.128, especially involved in technology products/services, see TechSandBox. Coworking space, advising, programs, and more.
