&gt; I&#x27;m playing with the idea of creating a startup that lets parents share their un-used kids toys with other kids.<p>By &quot;share&quot; do you mean &quot;rent&quot; the way most services that use the description &quot;sharing&quot; do (as suggested by the reference to AirBNB, a rental intermediary, as well)? Because your description of the operation doesn&#x27;t sound like sharing or even the rental that often goes by the name of &quot;sharing&quot;, but like a matchmaking services that replaces donating&#x2F;selling (or buying) used&#x2F;secondhand toys with a more involved process than typical donation scenarios (for the person giving the toy), but possibly less involved that typical sales scenarios.<p>I can see how, if the payments received were right, that might be attractive as opposed to existing options. If you really do mean AirBnB style rental, I think that would be less attractive -- part of the reason to get rid of no-longer-used toys is to reclaim the space.
