What the problem is

It's Monday morning. You need 30 qualified leads for this week's campaign. That means an hour in Apollo tweaking filters, exporting CSVs, cross-referencing company websites to write opening lines that don't sound like a template, then uploading everything to Instantly. By the time the first email sends, half your morning is gone. With Zero, you describe your ICP in plain English and get a fully personalized, campaign-ready lead list in minutes.

Zero searches Apollo for ICP-matching prospects

Zero translates your natural-language ICP into Apollo search filters — job titles, company size, location, and verified-email-only — then paginates through results to collect enough candidates. Emails are enriched via Apollo's bulk match API in small batches to maximize hit rate.

Company websites scraped for personalization context

For each unique company domain, Zero scrapes the website to understand what the company does, its positioning, and recent activity. This context feeds into the personalization engine so every opening line references something real about the prospect's company.

AI-personalized leads uploaded to Instantly

Claude generates a unique, natural-sounding opening sentence for each lead — no templates, no product pitches in the opener. The full lead list (name, email, company, personalization line) is uploaded to your Instantly campaign, ready to send.

Tips for better results

●Be specific with your ICP. Include job titles, company size range, and target geography — vague descriptions produce noisy results.

●Start with a batch of 20 leads to validate personalization quality before scaling up to 50 per run.

●Save your run ID. Zero caches Apollo and enrichment data to Google Drive, so you can re-personalize or re-upload without burning API credits.
