Sterling, your AI cofounder for the raise

Bring your mess.
Raise with clarity.

Your raise lives in a deck, a dozen docs, a hundred emails, old ChatGPT threads and your head. Bring it all to Sterling — it turns it into one raise strategy, keeps it current, and does the work: who to talk to, what to say, what's missing, what's next.

One raise strategy from everything you have
Investors researched; a pipeline that updates itself
Drafts in your voice; follow-ups that never slip

Start with what you have

A deck, a website, or a few sentences — connect the rest once you're in. No account needed yet.

Your raise strategy

The round: Target, instrument and closes, with dates
Who first: Which investors to approach, in what order, and who could lead
What's missing: The gaps investors will probe, before they do
The next move: One thing to do now — and the draft to do it

Kept current from every conversation, document and reply.

What Sterling does

A cofounder for the whole raise — not just the first email.

Raise strategy

Target, timing, closes and sequencing — who to approach first and who could lead — kept current as the round moves.

Investor research

Finds investors that fit your stage and sector, researches each one before it joins your pipeline, and spots warm paths in your network.

Readiness

Story, team, market, traction, the ask, diligence: what's on record, what's thin, and what to fix before the next meeting.

A pipeline that updates itself

Every investor's stage from your conversations and your Gmail. Who's waiting on you, who's gone quiet, what's due this week.

Drafts in your voice

Every email and follow-up, written the way you write, from what you've sent before — facts checked against your record. You send it.

Momentum, every day

The day's follow-ups drafted each morning, round updates to everyone in process, and monthly signals to the investors who follow you.

The raise plan

Your whole raise, always current.

Target, timing, committed so far, every investor's stage and the one next move — kept up to date from your conversations and your inbox, not a spreadsheet.

Readiness

Honest about what's missing.

Story, team, market, traction, the ask, diligence materials. Sterling tells you what's on record, what's thin and what investors will ask for next — before they do.

Proven in real raises

We raised our own round on Capsignal.

Capsignal is built by founders and capital raisers who have run fundraises from pre-seed to Series A. We ran our own raise on it first: the first angel checks came from investors who had followed us for only a few weeks.

Investors

Follow founders without the noise.

Founders on Capsignal send short monthly signals — real numbers, 500 characters, no decks to wade through. Following takes one email address. No account, unsubscribe anytime. When a founder raises, you've already watched them execute.

Connectors & family offices

Your investor relationships, private.

A private book of every fund and person you know, with Sterling to keep it current. Ask everyone where they stand on allocations in one round — each gets a 30-second form, no login — and the answers land in your book.

Questions

Before you start

What does Sterling actually do?

It reads what you bring — your deck and documents, files from Google Drive, your Gmail (who you emailed, who replied), meeting notes, pasted ChatGPT threads, a LinkedIn export — and turns it into one raise strategy: the round and its closes, which investors to approach first, what's missing and the next move. Then it does the work with you: researches investors, keeps the pipeline current, and drafts every email and follow-up in your voice.

Does anything get sent in my name automatically?

Never. Sterling drafts; you send. Every email opens in your own Gmail or Outlook, and nothing goes to an investor that you haven't read yourself.

What does Sterling see in my Gmail?

Only if you connect it, and only the headers — who, when, subject — of email to or from the investors on your cards. Never the text of an email, and everything else is ignored. Disconnect any time.

Do investors need an account?

No. Investors follow a founder with a single email field — no login, no app — and every email carries a one-click unsubscribe.

Is my data private?

Yes. Your deck, investor list and notes are yours alone — never shared with other users or sold. You can export your investor list as a CSV at any time.

What does it cost to start?

Nothing. Start with what you have, no card and no setup call.
