The hardest part of cold outreach is timing. A company that shipped something three weeks ago is hiring users, watching its numbers and willing to take a meeting; the same company eight months later is heads-down and ignores you. Nothing in the company search told you which one you were writing to.
Product launch is a new Activity Signal, next to Hiring, Advertising, Funding and the rest. Tick it and you get companies we have seen launch a product, with the usual window control: last 7, 30, 90 or 365 days.
The date is the launch's own, not the day we noticed it. That is the part that makes the filter worth using — a company that launched in March reads as March, however long ago we indexed it, so "launched in the last 30 days" means exactly that. Combine it with a country or an industry and you have a list of companies that are, right now, in the one month of the year when they most want to hear about something that gets them users.
It works over the API and in the MCP tools too: has_signal=product_launch,
with signal_within_days to set the window.
