Get feedback from one or more target audiences.
A service where you can “hire” people from your target audience for your new startup idea. You pitch your idea to them, and they give you feedback. The pitching will already make you rethink some aspects of your plan and your pitch, and the feedback will give you, even more, to think about.
Most projects start when someone has an idea he thinks will solve a problem. Then if he’s smart, he’ll try and test this assumption. What if we reverse the model?
An online service where we invite people to come and tell us what they want or need and can’t find (or can’t find anything good or close enough.) When you get many these that are centered around what seems like a unifying problem, do a deeper dive with those people, asking them for more and more insight into what they really need/want, what is their true problem and motivation (emotional as well as functional.) Based on these a more coherent idea can be formulated and then tested more widely. This might help uncover much more such problems and ideas than just starting with a thought.
Building a new product or service relies on feedback from your target audience. Especially when initially testing quickly and repeatedly your assumptions and solutions.
Either create yourself or partner with an existing public establishment (a coffee shop), and have a place where your target audience can hang and get special treatment (free or cheap food and drinks, comfortable armchairs, daily reading materials, and anything that makes them feel it’s “their private club”), in return for their participation and cooperation. A place where you can have planned meeting as well as ad-hoc ones (initiated by either side.)
If you want an audience (as an author, merchant, etc.), what are the best techniques to get it?
Publish articles only on the topic of getting an audience. All the different (and sometimes opposing) techniques, current tools and their use, theories and practice, etc.
You would like an online business but are having trouble finding the right niche for you. Something that you are comfortable with has a large irrationally passionate and, easy to reach audience, the right amount of competition, etc.
A service where you can get an expert to do a live consultation with you, where he will help you find the right niche for you.
