What the deck did well:

Clear problem and solution. The biggest strength of this deck is the clarity of the problem and the solution. They showed it in a way that was creative and could easily grab investors’ attention. That said, it did take several slides to make a point that they could’ve made in fewer slides. But, they made their point nonetheless.
Conservative use of screenshots. They included a good amount of product screenshots and didn’t go overboard with them.

What the deck would need to improve to secure funding in 2020:

More slide categories and information in general. The strengths outlined above are pretty much a description of the entire 10-page deck, save for a single “Revenue Opportunity” page at the end. Especially since there are countless dating apps now, they would need to add more in order to get a meeting.
More explanations. The problem and solution are clear, but there is no information beyond simply identifying them. Also, a lot of decks tend to take up slides with just visuals. It’s the founder’s job to make it clear what they mean. Tinder’s deck definitely could’ve done a better job of this. Explaining how the screenshots tie back to the problem and the solution would’ve been a good way to go.
