Targeting

Find the accounts worth chasing

Describe who you want in plain English. Winnow translates it into precise targeting, sizes the live market, and returns a scored, ranked list, not a raw dump.

  • Plain-English to filters. "VPs of RevOps at Series B fintechs that are hiring" becomes a real, editable search.
  • Fit and intent scoring. Every account is ranked on how well it fits and whether it is showing buying signals now.
  • Or bring your own list. Already know the accounts? Paste them and Winnow researches each one for you.

Buyer intelligence

Know every buyer before you reach out

Reveal the people inside each account and get an intelligence brief on each one. Why now, the angle that fits, and the talking points worth leading with, every claim grounded in real data.

  • Account and person briefs. Role, work history, and a clear "why now" for the conversation.
  • Grounded, not guessed. Briefs are scored for grounding and labeled by source, so you can tell fact from inference.
  • Competitive context. See where you win and where a rival is stronger, ready to inform the pitch.

Messaging

Outreach that is written, not templated

Every email leads with the account-specific hook and your real offer, tailored to the buyer's role. What you preview is exactly what sends, byte for byte.

  • Role-aware copy. Written for the buyer in front of you, led by your offering, not a generic mail-merge.
  • What you approve is what sends. The preview is the exact message, with a grounding score shown at the approval moment.
  • Multi-touch sequences. Build the follow-ups, schedule the cadence, and let the campaign run.

Subject: Ramp time for your new RevOps team

Saw you stood up RevOps six weeks ago. Most teams lose the first quarter to tooling and data cleanup. We help SaaS teams compress that to weeks, with the pipeline already wired...

Emails are scored for factual grounding, with unsupported claims flagged before approval.
