The whole go-to-market motion, in one platform

Winnow runs a six-stage intelligence pipeline, from understanding your business to writing the outreach. Each stage is editable, grounded, and governed.

Stages 1 & 2 · Understand and segment

It learns your business before it does anything

Winnow reads your site and extracts what you sell, who you sell to, and how you position. That understanding grounds every segment, score, and email that follows.

  • Company profile. Positioning, value props, and buying determinants, read from your own site.
  • Persona segments. The buying titles that fit your offer, each with a live market count.
  • A reusable knowledge base. Add links and notes once, and every run gets sharper.

Stages 3 & 4 · Size and source

Honest market sizing, then the accounts that matter

Winnow counts the live market at every tier, then sources and scores the accounts inside it. You see the real addressable market, not a vanity number, and a ranked list to work.

  • TAM, SAM, in-market now. Counted against a live B2B database, not estimated.
  • Fit and intent scores. Hiring, funding, tech, and traffic signals roll up into a rank per account.
  • Editable targeting. Narrow by segment, adjust the filters, and re-score in place.

Stage 5 · Buyer intelligence

Reveal the people, then the reason to call

Reveal the buyers inside each account and generate an intelligence brief on each one. Every claim is labeled by source and scored for grounding, so you always know fact from inference.

  • Account and person briefs. Why now, the angle, and the talking points worth opening with.
  • Provenance on everything. Verified, grounded, or inferred, each clearly labeled.
  • Competitive landscape. Where you win and where a rival is stronger, editable and saved.

Stage 6 · Messaging and campaigns

What you preview is what sends

Winnow writes a tailored opener for every buyer, led by your offer and their context. Sequence the follow-ups, set the cadence, and approve the exact copy that goes out.

  • Byte-for-byte preview. The message you approve is the message that sends, no surprises at send time.
  • Multi-touch sequences. Build the cadence, schedule sends to real working hours, and track engagement.
  • Open and click tracking. See which touches and personas land, per campaign.

Sending

Connected to the mailbox you already use

Winnow sends from your own mailbox, as individual one-to-one emails through the email account you already use. There is no separate sending domain and no bulk-email infrastructure. Because each message is a normal email from a real mailbox, it has the best chance of reaching the recipient's inbox.

  • Uses your own mailbox. You connect the email account you already send from, and Winnow sends through it, one message at a time.
  • Built for inbox placement. Individual, personalized emails from a real mailbox read as normal mail, not the bulk marketing that filters are tuned to catch.
  • You stay in control. You approve every message before it sends, and messages go out at a measured pace, not in a burst.

Why we send from your mailbox

Short version: your outreach goes out as ordinary one-to-one email from your own mailbox. Here are the details, in case you are wondering.

Will this affect my domain or email reputation? +

Winnow sends through your own mailbox, so your email behaves the way it already does. There is no separate sending domain and no change to your DNS. As with any outbound email, reputation depends on sending relevant, wanted messages at a sensible volume, which is exactly what one-to-one outreach is, and what the approval step and measured pacing are there to support.

Why send from my mailbox instead of a bulk email tool? +

Bulk email tools send high volumes through shared or dedicated marketing infrastructure, which mailbox providers filter more aggressively. A personalized, one-to-one email from your own mailbox reads as normal correspondence, so it is more likely to reach the inbox and earn a reply. For sales outreach, that difference matters.

Do I need to set anything up? +

You connect your mailbox once, which authorizes Winnow to send on your behalf. There are no DNS records to edit and no separate sending domain to warm up. Once connected, you are ready to send.

Is this email marketing or a newsletter blast? +

No. Winnow is for one-to-one sales outreach. Each message is addressed and personalized to a single person and approved by you before it sends. It is not a newsletter or mass-email tool.

How much control do I have over sending? +

Full control. Nothing sends without your approval, you set the pace, and you can pause or stop at any time.

Winnow, the orchestrator

One agent you talk to, a team working underneath

Winnow is the one agent you talk to. Underneath, a team of sub-agents each own a job: research, targeting, copywriting, deliverability. You direct one place, and the whole team executes. Here is what that team can do.

Build an audience

"Find Series B fintechs hiring RevOps and add the VPs." Winnow assembles and scopes it.

Refine the targeting

Narrow by segment, size, geography, or signal in a sentence, and watch it re-score live.

Draft a sequence

Describe the cadence and Winnow scaffolds the multi-touch sequence, ready to refine.

Write and rewrite copy

Generate an opener for a persona, or rework one you have, on brand and grounded.
