Deployment readiness
Interested isn't the same as able.
Plenty of investors will happily take a meeting from a fund that's two years from its next raise. Readiness tells you whether a firm can actually write the cheque now.
We look at
Fund age. Firms in years one to three of a fund are usually deploying. Late in a fund's life, new cheques slow down.
Pace. How many new investments they've made in the last six months, compared with their own normal rate.
Follow-on load. How much of their recent activity is backing existing companies rather than new ones.
Signs of a new raise. Registry filings and announcements that suggest the next fund is on the way.
Output: each fund gets a readiness label: Deploying, Slowing or Between funds, with the evidence listed underneath.
Readiness is an estimate built from public evidence. We show our working so you can disagree with it.
- Nine new investments in six months, ahead of its own three-year average
- Two of the last nine cheques were follow-ons
- Fund III closed on the registry in 2024; no filing for a fourth

Every investor on your list gets a fit score from 0 to 100. Click it and you'll see the parts, each with the signal and source behind it.

- Partner fit (the individual, not just the firm)
Weighting behaviour over positioning is deliberate. What a firm says it invests in tells you less than what it wrote a cheque for in the last six months.

Old news, ranked lower. Automatically.
Signals lose weight as they age, and different kinds decay at different speeds. A post asking founders to DM fades in weeks. A fund close stays relevant for a year or more. Your list re-ranks itself as the world moves, so this week's top ten reflects this week.
Hear about it the day it happens.

Send a signal into a Workflow to update your pipeline or start a follow-up.
Every signal has a date and a source you can open.
If one doesn't, that's a bug, and we want to hear about it. A tool that tells you something confident and unattributable is worse than no tool, because you'll act on it.

How fresh are signals?
Sources are read continuously, and most categories are checked at least daily. {{TODO: confirm cadence per category and link to /data-sources}}
What's the difference between a signal and investor data?
Investor data is who a firm is: team, thesis, fund size. A signal is something that changed. Yellowtail has both, and ranks on the second.
Do you cover angels as well as funds?
{{CONFIRM}}
Can I add my own investors to watch?
Yes. Import a list or connect your CRM and we'll monitor those investors too. {{CONFIRM: import formats + CRMs}}
How is deployment readiness calculated?
From fund age, investment pace, follow-on activity and signs of a new raise. Every readiness label lists the evidence behind it.
