About xbase

We're a small team of hackers building the best social media client for productivity on Earth.

Our story

My co-founder and I met in Danang, Vietnam three years ago at a coworking space. We have been hanging out and talking about web 3 and the future of money every week since then. We researched crypto full-time in 2021 and that’s when we saw the opportunity for Xbase.
Twitter is a social network where smart people hang out and comment on stuff. You can see conversations between smart people in any field on any topic for free. Twitter is a goldmine of insights. We went to Twitter to see what smart people said about crypto, but we quickly learned finding good tweets was hard.
The Twitter search results were spammed with posts generated by bots. It had no way to filter the specific topics from people. Since Twitter started as a news platform, its design prioritizes the newest info so old tweets rarely get resurfaced. We found some good tweets and used Notion to organize them, but Notion UX was slow and the search was limited.
So we decided to build a better way to use social media.

Where is Xbase located?
Xbase is a fully remote team. As a member of our team, you will be invited to work wherever you're happiest and most productive. We are incorporated in Delaware.
How big do you think the market is for this?
We plan to serve knowledge workers who use Twitter every day: startup founders, engineers, news reporters, marketers, lifetime learners, recruiters, salespeople, etc. According to the pitch by Elon Musk, there will be ~150 million users who will pay for the premium Twitter subscription, Twitter Blue by 2028. If we capture 5% of those users, we would make ~$300mil/yo.
What stage is the product at?
We have some paying users and trying to scale the features and marketing side of business.
How is Xbase different from Twitter bookmarks?
Twitter bookmarks are great for saving tweets you want to read later. But that's it. They're not searchable, and you can't sort them by date or other criteria. It's hard to keep track of what you've read and what you haven't. xbase is an all in one tweet manager so it’s more capable.
Do you support other browsers?
No, we only support Chrome. There are no near-future plans to add multiple browser support.
