Raise from a warm list. Not a cold one.

Capsignal turns the investors you meet into a list that follows your progress. The ones from events, from intros, already on your cap table. A short signal keeps them warm, so when you open your round it's half full before you email a stranger.

We raised our own round on it.
Tested at events in NY, Atlanta + London.

Get them on your list

Meet them anywhere. Capture them once.

You meet an investor at an event, they scan your Beacon, and they're on your list, following where you're headed, with the option to book a meeting right there. The investors you already know? You just send them the link.

The conversation ends. The relationship doesn't. Months later when you raise, they're still following, and they remember exactly who you are and what you're building.

The problem

The round is won before it opens.

Every founder runs the raise. Almost nobody runs the part before it. Capsignal is that missing part: capture the investors you meet, keep them close as you grow, and open your round with a warm list that's ready to move. A half full round fills faster, because investors move when others already are.

One warm list

Cold vs warm

Two ways to run the same raise.

	Cold raise	Warm raise
Outreach	200 cold emails to strangers	40 warm intros you already have
Meetings	8, if you're lucky	Most take the meeting
The relationship	No reason to trust you yet	They've watched you grow for months
Diligence	Starts from scratch, drags for weeks	Half done, they've seen the numbers move
Day one	Round at 0%	Round half full
3 months later	Still raising	Closed, back to building

The cold raise is 200 emails to people who don't know you. The warm raise is 40 who've followed you for months, most of whom take the meeting, and a real share of whom write the cheque.

How it works

A list, a format, and almost none of your time.

Founders

We raised our own round on Capsignal.

My cofounder and I both come from capital raising. We've helped founders from pre-seed to Series A, and raised $2.5M for our own companies. We ran the warm-list method by hand every time, because it's what separates the founders who raise easily from the ones who grind.

Then we built it into a tool and used it ourselves. Our first angel checks came from investors who'd followed us for only a few weeks. Warm beats cold even on a short runway, and the longer they follow, the warmer they get. Then we took it to events in New York, Atlanta, and London, and over 20 investors followed Capsignal on the spot.

Questions

Before you start

Do the investors I add need an account?

No. They follow with a single email field — no login, no app to download. Zero friction on their side is the whole point.

How much work is this for me?

About thirty seconds a month. You send one short signal — a few lines on what moved: revenue, users, product, a hire. Capsignal reminds you and drafts the shape; you write it and send.

Is my investor list private?

Yes. Every email, source, and note is yours alone, never shared or sold. You can export the whole list as a CSV at any time and take it with you.

What does it cost?

Free for 14 days, no card to start. It stays free after the trial if you don’t upgrade — Pro just lifts the limits and adds the extras.

Can investors book a meeting or unsubscribe easily?

Both are one tap. Add your own calendar link and it rides along on every signal; every email also carries a one-click unsubscribe, so your list stays people who actually want to hear from you.

Does anything get sent in my name automatically?

Never. Capsignal drafts and reminds; you send. Nothing goes out to an investor that you haven’t read and approved yourself.
