CalcStack is a lead generation platform that replaces static contact forms with interactive tools visitors actually want to use. Instead of asking for an email upfront, CalcStack gives visitors something valuable first: a personalised calculation, a diagnostic score, an AI-generated output, or a data-driven recommendation. It then captures their details in exchange for the full report.

The platform offers a number of different interactive content: calculators that crunch real numbers against industry benchmarks, scorecards that assess readiness and health across weighted criteria, decision engines that compare two options with data-driven recommendations, benchmarks that show visitors how their metrics stack up against their industry, graders that evaluate content and provide specific improvements, quizzes that match visitors to personalised recommendations, and AI generators that create business names, cold emails, taglines, and more on demand.

Hundreds of pre-built tools span multiple industries including marketing, sales, finance, SaaS, HR, real estate, ecommerce, energy, events, automotive, insurance, education, home services, and cleaning. Every tool is config-driven, powered by a single calculation engine, so businesses can also build custom tools using drag-and-drop builders.

Embedding takes one line of code and works on WordPress, Webflow, Wix, Shopify, Squarespace, Framer, and HubSpot CMS. The embed funnel uses a blurred-results teaser gate: visitors see partial results, then enter their email to unlock the full analysis and download a branded PDF report.

Captured leads include every input the visitor entered, their results, and their contact details, giving sales teams rich context before the first conversation. Leads route to HubSpot, Salesforce, Mailchimp, Slack, Zapier, or Google Sheets
