A room of new work, every week.
What this is
People on X post threads like "Founders, drop what you're building 👇", and dozens of builders reply with a link and a line about their product. Those threads fall out of timelines within a day, and most replies are buried under the first few.
XFounders keeps them. Each week it shows every product from the best of those threads: one case per product, credited to the person who replied, in their own words. Nobody signs up. Builders are found, and they can ask to be removed.
How a room is built

Find the threads
Search X for posts from the last 7 days that ask founders what they're building, then take the busiest ones no earlier room used.
("drop what you are building" OR "drop what you're building" OR "drop your project" OR "drop your startup" OR "drop your product" OR "drop your saas" OR "what are you building" OR "show me what you're building" OR "share what you're building" OR "shill your project" OR "shill your startup" OR "plug your startup" OR "promote your saas") -is:retweet -is:reply lang:en min_replies:50 -min_replies:101 - 2
Keep replies that link somewhere real
Only replies with a link stay. Links to these sites are set aside before any AI sees them.

Ask a small model one question
Is this person promoting their own product? Claude Haiku answers with a label and a reason. It never writes anything you see here.
model claude-haiku-5-5 { "label": "promo" | "unsure" | "not_promo", "reason": "string, ≤ 200 chars" } - 4
A person approves every case
Nothing goes on the wall on a label alone. Each one is read, then approved or turned away by hand.
status: pending_review → approved

Use the founder's own words
Labels come from the product's own preview or page, in this order. When there's nothing, the label says so.
x preview → og:description → <meta name="description"> → <title> → domain only
House rules
- Builders
- The people replying. Thread hosts are credited as lenders, never as builders.
- One case each
- One case per product, however often it's posted. Repeat appearances show as back again.
- No ranking
- Every case is the same size, and the order is drawn by lot each week.
- Always linked back
- Every case links to the builder's original reply, and its options menu links to their X profile.
- Deleted means gone
- Posts deleted on X come down at the next release.
Opt out
Ask to be removed
No form, no account. A DM from the listed account is enough.
- DM @MrAdityaParab from the listed account.
- Every case with that handle is hidden, in every room, co-built ones included.
- It's gone at the next release, and the handle stays on a private list so it's never added again.
Deleted your post on X? Its case comes down on its own.
Credits
XFounders is built by @MrAdityaParab.
Every product, name, description and image belongs to its maker, and every reply to the person who posted it. Threads and profiles come from X; each room credits the hosts whose threads it drew from. Replies are sorted with Claude Haiku, and search runs on Pagefind.
