FAQ

Questions, answered honestly

You haven't launched. What exactly am I paying for?

Early, discounted placement in a capped number of sponsored slots, plus a lifetime "Founding sponsor" badge. We have no traffic numbers yet, so we don't sell on traffic: you get the slot and the price before both go up.

When does my 6 months start?

On launch day, October 30, 2026, or the day you buy if that's later. If your category opens later (web-data/crawl APIs, proxies, computer use), it starts when that category goes live.

What if you don't launch, or I change my mind?

Not live by November 19, 2026: every founding payment is refunded in full automatically; before launch, a full refund on request at any time. If we ever shut down during your term, we refund the unused months pro rata.

Who visits the site, and how will traffic grow?

Developers and teams choosing tools for web-agent projects. Traffic comes from search pages built on our data, AI-answer citations of our tables and trends, and launch distribution (directories, awesome lists, a free public benchmark, a weekly digest); SEO takes months, and we'll be transparent about it.

I run an agency. Is this for me?

Yes: "Build partners" lists vetted teams that build browser and web agents, tagged by stack. We can't promise leads before launch, but you get an early profile next to the tool pages buyers already read.
