We just held our fourth week of the Hacking for Defense class. This week the teams turned the corner on understanding beneficiaries and finding product/market fit. The 8 teams spoke to 115 beneficiaries (users, program managers, etc.); we sent each team a critique of their mission model canvas; we started streaming the class live to DOD/IC sponsors and other educators; our advanced lecture explained how to go from concept to deployment in the DOD/IC; and we watched as the students got closer to understanding the actual problems their customers have.
