The internet is the greatest dataset ever created. Today, we're launching the Riveter Dataset Builder to make it possible for anyone to get custom, fresh data from a prompt.

Data you can buy is frozen in time. Built for everyone = built for no one. It reflects whenever someone last crawled it - could be last quarter, could be two years ago. The web is live. Infinite. Specific to exactly what you need.

With Riveter, you describe what you want and our agents go find it. Fresh. Structured. Enriched. - Every company listing a specific vendor on their subprocessor page - Every prospect that switched to usage-based pricing - Every law firm in the US and their attorneys One prompt. Thousands of rows.

ChatGPT and Claude can reason about the web. They can't do this at scale. You can't ask an LLM to return thousands of enriched records reliably.

We tested it against Clay and Parallel, asking it to collect the @ycombinator Winter 2026 batch: both returned incomplete lists alongside companies from other batches. Clay even returned "Y Combinator" as a company. Both lists came at a MUCH higher cost. @riveterhq got it right.

Teams at OpenAI, Snap, and Fermat are already using it to build datasets they never could have justified creating manually. Try it free at Or reply "LIST" to get 2,000 free credits on us.

can confirm, the dataset builder is SO awesome. And the accuracy of the data is unparalleled

Brilliant!

@garrytan Congrats on your launch!

@garrytan Thank you!

interesting how data is becoming something you don’t prepare upfront anymore, you just get it when you need it. that changes how people start building things from day one.

For sure - we see the future as a combination of structured and unstructured data sources combined to get to exactly the dataset you need

The internet: an unstructured mess finally made queryable. Fresh data pipelines beat stale datasets any day.

You GET it

Data freshness is the real moat in AI. Smart move building the picks and shovels.

the internet as dataset is obvious in hindsight but building the tooling is hard. i could see myself using this.
