First lines for lead-gen agencies

Client campaigns personalized in minutes, not VA-days

Agencies burn $0.15–0.50 per line on VAs and per-credit tools. ColdOpen writes the whole client list with your own AI key — the marginal cost is whatever your provider charges, about $0.0002 a line.

Per-line pricing eats your margin

At 5,000 leads a month, per-credit personalization tools cost more than the SDR seat. One-time $19 plus your own API key ends that line item.

VA quality drifts

Human personalizers get tired by row 200. The prompt doesn't — every line references something real about the company, capped at 25 words.

Client voice varies

Direct for the fintech client, warm for the HR-tech client, witty for the DTC brand. One toggle per campaign.

Common questions

Can I use one license across client accounts?

Yes. The license unlocks the tool in your browser — run as many client campaigns as you like.

Do my clients' lead lists touch your servers?

No. The CSV is parsed in your browser and the AI calls go directly to your provider. Nothing is uploaded to us.

What does it cost?

First 10 lines free, then $19 once for unlimited. You bring your own OpenAI or Anthropic key, which stays in your browser and costs you fractions of a cent per line.
