The GrowthHacker community can play a pivotal role in helping you to find ideas for your project.
Within the community, we host AMA's (Ask Me Anything) with industry professionals. There are also discussions around various aspects of growth which provide an easy way to connect with other Growth-oriented professionals who are also using Projects.
The community can also provide you with some great resources for solidifying hypotheses for your tests. If you're not a member already, we encourage you to sign up today!
