In the tech/AI race, many companies keep adding layers — features, tools, products — often on top of a weak core. Over time, complexity grows and control fades. We take a different approach. We focus on getting the foundation right continuously. Because a product is only as

Your best customer might buy you. Or copy you. If they copy you, they’re rebuilding yesterday while you’re already building tomorrow.

This is me all the time when trying to explain (with the best intentions) how we can help X/xAI teams with their products😅

https://t.co/ctvziYrTgA Topic specific timelines are a much needed feature! And X literally has people talking about EVERY single topic possible, so it's totally doable to make this. In fact, this was basically the project we made at the xAI Grokathon in London last week! X
The @xAI team is working on providing For You tabs that are specific to topics. For example, a “For You AI” that is focused only on artificial intelligence with no political rage bait. This would be like automatically generated follow lists with content ranked by quality.

Yes! We also think that this is the way to solve onboarding. X truly has people for EVERY SINGLE niche. It's crazy when you look at the actual data. But doing this manually just can't be a good use of time, and especially not when a partner already has this, scaled to every

This post and the replies perfectly illustrate what goes wrong with X advertising, largely because X/Grok’s system optimizes for the wrong things. It prioritizes click behavior instead of connecting a real, relevant audience to the advertiser/product. The fix is simple. Very
I don't have a ton of experience with online ads, but I have some. And unfortunately X is just terrible. Recently I had $8K in X ad credits and used them up targeting my followers. 600K impressions, 6.5K clicks, and only 3 conversions. Despite exclusively targeting my own

@nikitabier @joshelman Hey Nikita, have you seen this? We've build this website for the Grokathon in London that showcases our ability to instantly create a relevant timeline from 1 simple topic. Could it be helpful? https://t.co/ljaLzAmSG4
This is exactly what we built today at the xAI Grokathon! From just one prompt and our own Authority Index, we can create a fully custom timeline. Importantly, this is NOT a filter on the X timeline. These are posts from users on our Authority Index.

Have you ever wondered how highly you're ranked on this platform? It's just a small feature we added to our Grokathon project, but I think it's really cool to see your interests and a little AI summary of the account.

The X algorithm should be promptable. Prompt: No politics today - just the best AI innovations. @nikitabier @elonmusk

Working with X data every single day is the best thing. But over the past 1.5 years, I’ve discovered another passion: running. Training for races makes progress undeniable. Over time, it shows you exactly why you trained, and whether you did the work right. Every race is a clear

My regretted minutes on X are at a peak, even though my total usage and engagement probably is too (which has to do with the fact that I truly believe I should be able to spend 24 hours a day on this platform). I like the idea of the For You page IF it shows me what I actually
