Spectacular. These guys really know what they are doing. These are the kind of guys that promise 10 and deliver 20. Normally we are struggling with the teams we work with for them to achieve our expectations (product and time-wise) and with Speed Boostr team we were astonished. They would never "just stick" with what we wanted, but were constantly giving feedback based on their previous experience and recommending us actions to move forward even if this meant more work for them (this happened a lot).
