Interest signals for rounds still taking shape.
Specter detects which investors are engaging which companies and founders: who is interested, how strong the interest is, and what they're looking at. Signals often land weeks before a round or acquisition goes public, so you're in the conversation first.
Trusted by 400+ elite firms
Investor demand, visible weeks before the announcement.
Signal types
Company and Talent: demand aimed at a company, or at a person before the company exists. Every signal names its target, so one feed covers the round forming and the founder it forms around.
Investors and sources
Every signal names the investors engaging and the source it was observed through: insider, venture capital, angel, journalist, influencer, investment bank, private equity, or investor.
Scores, dates and funding context
Each signal is dated and scored 1-10 for strength, and carries the target's funding at signal time: total raised, last round size, and last round date.
Summary and entity links
A plain-English line on what was observed, with the entity ID to pull the full company or person record in one call.
Demand, detected as it builds.
Interest Signals show which investors are engaging with companies or founders, often weeks before a funding round or acquisition becomes public. Every engagement lands as one scored signal, ready to act on the day it's detected.
Investor activity
Which investors are showing interest, named on every signal: funds, angels, banks, and the people around them.
Signal strength
A 1-10 confidence score built from engagement patterns, so you can size the interest before you act.
Companies and founders
Interest aimed at a company, or at a person before the company exists. One feed covers both.
Eight source types
Insider, venture capital, angel, journalist, influencer, investment bank, private equity, and investor engagement.
Watch a round form before it's announced.
One partner follows a founder. A principal reaches out the next week, then a third firm starts tracking the team. Specter catches each engagement and scores it, so the pattern is visible while the round is still forming.
