Companies

The company, its stack, and its org.

Who funds it, what it ships, who works there. Agents work out the tech stack behind the domain and build the org chart one person at a time.

Frequently asked questions

What is Autumn?

People research as a primitive. Autumn resolves fragmented information on the web into an index of every person in the world: relationships, work history, contact info, and digital footprint. Agents query it for whatever you need, from a prospect list to a background check.

How is Autumn different from ZoomInfo, Clay, or Apollo?

Those are databases and workflow tools. You get the rows they already have. Autumn runs live research at request time: agents read news, filings, registries, code, job posts, and social the way an analyst would, then assemble the answer.

You also get what no database has indexed yet. Agents watch incorporation filings, event pages, and launch pages, so new companies show up in Autumn first.

Who is Autumn built for?

Sales teams researching accounts, recruiters sourcing candidates, investors mapping markets, and risk teams screening people and companies. Anyone who needs deep research at scale instead of another static list.

Where does the data come from?

The open web: incorporation filings, LinkedIn, X, GitHub, event pages, news, code, and company sites. Every cell links back to its sources, so you can check any claim in one click.

Can I use Autumn programmatically?

Yes. The same agents are available over the API. Find companies, enrich rows, build profiles, or run screening from inside your own product.

Do I need a credit card to try it?

No. Sign in and run your first research task on the free tier.
