Your accounts, not the whole market.

Put the companies you sell to, back or compete with on a list. When one of them raises, gets acquired, hires a new executive or opens a senior role, you hear about it.

One setting turns a list into alerts.

Set Deliver for on a webhook and it only fires for companies on that list. Event filters still apply on top, so you can ask for big rounds and C-level moves at your accounts only.

Watchlists, answered.

The short version before you build a list.

What is a watchlist for?
A watchlist is a set of companies you care about: accounts you sell to, a portfolio, competitors. Point a webhook at it and you only hear about those companies instead of the whole feed.
How do I add companies?
By domain, company name or LinkedIn URL, one at a time or as a CSV. Each entry resolves to one company, and every add tells you what was added, what was already on the list and what could not be found.
How do alerts work?
Create a webhook and set Deliver for to the list. New funding rounds, acquisitions, executive moves and hiring signals for those companies are sent to your endpoint as they are confirmed. Webhook filters still apply on top.
Do watchlists cost credits?
Creating and editing lists is free. You spend one credit per delivered webhook event, the same as one record from the API.
How big can a list be?
Up to 50,000 companies per list and 100 lists per workspace.
Which plans include watchlists?
Growth and Scale, together with webhooks.
