I spent 2024 building an awesome TV series recommendation platform. It worked by matching you to professional critics who shared your tastes, by basically crawling Rotten Tomatoes and getting an LLM to grade the reviews out of ten. The recommendations were awesome, and having a personalized Rotten Tomatoes where you could read about and research the show using reviews by people who felt the same way as you did about stuff was freakin' cool.
However, getting people to actually sign up and use the app without a massive marketing budget was very, very difficult. The stickiness to get people to go back to it is difficult. Asking people to input their preferences in the first place is hard. People also simply didn't believe the recommendations, and wouldn't take chances on shows; the computer can recommend The Detectorists to as many people as it wants, but there's a high number of people who would love the show but will dismiss it looking at the cover image and having a quick read of the synopsis.
The recommendation part isn't super hard, the getting people to use a B2C app is super hard.
Even if people wanted your standalone app, they're not going to sit and enter the kind of rich data a decent recommendation engine needs. It really has to be a tool that gathers data about you as a side-effect of you using it.
This has severely fallen out of fashion since the 2000s, but it used to be not uncommon that when one web app wanted to do actions on your behalf on another web app, it would just take your username and password and log in as you. According to Cory Doctorow (I wasn't there) Facebook did this to MySpace.
For Netflix in particular, logging in from your server would probably trigger anti-account-sharing, but you could avoid that by making the requests you need from the user's app on their device, not from your server.
I think the industry feels like it's illegal now, but I don't think it's actually illegal? since there's no criminal intent. I don't think it's the same, legally, as when a criminal steals your login details and logs in as you. But I'm not a lawyer and this is not legal advice. But my evidence is that there are apps (e.g. POLi) that do this with bank accounts and still don't seem to be in any trouble. Even the banks don't seem to be locking it out as that would hurt the customer's relationship with the bank.
Now, if someone made a "Recommendation-Engine-in-a-Box", where someone who wanted to make a recommendation app for themselves would supply the content and could tweak the algorithm and the design, I could see that being successful in this market :)
I guess SaaS aimed primarily at founders makes it a meta startup? The snake is eating its tail.
Would probably be worth it even if just to have a consistent UI across services.
Isn’t this what Netflix used to be
