I'm a lot more hesitant to say: Build something people really need because of examples like Instagram/Snapchat etc. Were those really needs? Were people really "needing" Instagram at the start? I think businesses should target pain points/needs but I'm now of the opinion that its best to start with targeting a sizeable target segment and then work out pain points/products/needs/inspiration from there. As long as there are customers/users/market, there will be possibilities. I know it might sound similar to others but a need can always be argued into existence or a need can be hidden so deep you can't even qualify it until the company/product is out (hence why some startups pivot or end up doing some exploration before they take off). But it is much easier to have a target group in mind and then target them and figure out a distribution channel to reach them than figuring out needs from the start. I think come up with your target customer group first, study them and then figure out the marketing and messaging needed target them and then things get easier from there.
