Please allow me to pick on a VC-backed product that I think won't work, and that you shouldn't try to emulate.
If you're thinking of building an app like Sunshine Contacts, don't. It won't work.
It's an app that aims to fix a problem that doesn't really exist. As a creator, you'd think it's a nifty problem to solve there, something new and innovative. A pain point that you've probably felt yourself! But if you build an app like this, it won't make you money. And hint hint, despite the fact that it's funded by investors with clout (Marissa Mayer, no less), they won't make money either.
Sunshine Contacts uses AI to fill up your contacts app (iOS) with up-to-date information.
Their landing page seems to be doing all the right things:
Despite all that, this app won't work. These VCs are deluding themselves.
When you're trying to put yourself in the mind of a buyer, to see if there's going to be a sale, there are three levels you can get to, to qualify how well you understand, how well you can predict success or failure.
Sunshine Contacts seems to be an idea created from a Level 2 understanding:
That's not a real struggle to warrant a hunt for a better solution, and that aspiration isn't strong enough.
So let's look further. Let's try to get to Level 3.
To find the situations that are ripe for the "switch", let's use "when" statements. This is also known as Job Stories for all the Jobs-to-be-done folks out there.
Here, we set up the struggle. It's not a hard struggle, and you see that the user will go for an alternative that's good enough: search online for information on that person.
But sometimes a switch-worthy struggle swells up with repetition. The "enough is enough" condition is built up by recurring annoyances and a bigger context:
Nobody uses their own contacts app to contact 5 people in a row (let alone 15 more). That is, unless you’re a venture capital douchebag. All the sales creeps use a proper CRM tool. Does Sunshine Contacts populate CRM tools using AI? Maybe that’s what they should concentrate on.
That's my rant. I wrote a more detailed piece, going further into a showing why this idea won't do the job, including if you consider an even broader job-to-be-done: the person wants movement in their career and wants to get ready for the big move. Even still, the app won't get bought.
Don't build apps like Sunshine Contacts.
