How does CalcStack capture leads?▾
CalcStack turns website visitors into qualified leads through a 6-stage value-first funnel, reducing your cost per lead while improving lead quality. Visitors use the interactive tool, see personalized results with industry benchmarks, then enter their email to download a full PDF report. The business receives the lead with every input, every output, a quality score, and benchmark positioning — sent straight to their CRM via HubSpot, Salesforce, Mailchimp, Slack, Google Sheets, Zapier, or custom webhook.

What types of interactive content can I create?▾
CalcStack offers 7 content types: calculators, scorecards and assessments, decision engines, benchmarking tools, graders, interactive quizzes, and AI generators. Each captures different data and engages visitors differently. All tools are ready to embed.
How do I know which tool to embed on my website?▾
It depends on your goal. Calculators work best for quantifiable decisions like ROI and pricing. Scorecards work best when visitors need to assess their current situation. Decision engines help visitors choose between options. Quizzes recommend your services based on visitor needs.
What data do I get from each lead?▾
Every lead includes their email, every input they entered, every result they received, and an automatic quality score. For scorecards you also get their category-by-category breakdown. For decision engines you get their situation data and which option they prefer. This gives your sales team complete context before the first conversation.
