For Startup Founders

The .com you want isn't available.
We'll tell you the moment that changes.

Your launch name is parked. The owner ghosted your email. Cold reach-outs went nowhere. Add it to your watchlist — we watch it 24/7 and email you the second WHOIS, DNS, ownership, expiry, or a marketplace listing changes. Be first, not lucky.

Expiry & renewal

The first date that matters for a drop catch

Marketplace price changes

Even a 20% drop ships an alert

Four moments founders use this

Real scenarios, not feature checkboxes.

1

Your launch name is parked

You finally picked the name. The .com goes to a parked page with no listing, no contact form, no reply to your outreach email. Add it to your watchlist — we ping you the moment the WHOIS, nameservers, or ownership flips. That's usually the first sign the owner is preparing to sell, transfer, or let it expire.

2

The owner won't reply, but the domain is for sale

Most aftermarket sales never hit Sedo or Afternic publicly until the seller decides to list. We watch every major marketplace daily — if your target shows up with a price, you'll know within hours, not weeks.

3

Brand protection before a Series A

You're raising. The last thing you need is someone snapping up the .co, .io, .ai, or a close typo right before press hits. Watch every variant. Get alerted on new registrations, ownership transfers, and DNS changes that signal a competitor or squatter is moving in.

4

The pivot is coming

You're rebranding to that domain you sketched in the founders deck. Watch it now so the moment it becomes available — by expiry, drop, or owner change — you're the first to know and can move within the day.

Common questions

How fast will I get notified?

We check every watched domain three times a day. When something changes, the email goes out within minutes of detection.

How many domains can I watch?

Up to 25 on your watchlist at once. Enough for your main launch name plus every realistic backup, variant, and TLD.

Does this help me actually buy a domain?

We don't broker or buy on your behalf — we make sure you're the first to know when it's buyable. From there you act fast at the marketplace, drop catcher, or via direct outreach. Being first is the whole game.

What if I just want to watch one domain?

Perfect use case. Add it, forget about it, get the email when something happens. $99/year covers up to 25, so you have headroom when you add backups or variants.

Stop checking. Start getting notified.
