The alarm

Your phone lights up before the coffee.

Three notifications. One Slack from your co-founder. One calendar reminder for the 9 AM partner meeting. And one email with a subject line that cuts through the noise — “Signal 001 — Series A valuations just broke a record.”

You open it before your feet hit the floor. By the time you reach the kitchen, you know what the market did last week.

The data you've been manually scraping, already compiled.

Every week, Signal processes 1,000+ funding announcements, strips the PR spin, and surfaces the actual numbers — median valuations, check sizes, and the investors who wrote them.

The chart on the left? That's from Issue 001. Median Series A pre-money crossed $34M for the first time in Q4 2025. You should know this before your investor picks up the phone.

“I used to spend 40 minutes on Crunchbase every Sunday night. Signal gave me that time back.”

— Priya Mehta, Founder, Meridian Health (Series A, $18M)
