Why CalcStack
Turn your website into a lead machine
Interactive content converts 3–5× better than static forms. CalcStack gives you hundreds of tools to embed — calculators, scorecards, decision engines, benchmarks, graders, and quizzes — without writing a single line of code.
Launch in minutes, not months
Pick from hundreds of pre-built interactive tools — calculators, scorecards, decision engines, benchmarks, graders, and quizzes. Embed anywhere with a single line of code.
Capture qualified leads on autopilot
Gate results behind an email form that feels natural, not pushy. Every lead arrives with their inputs, scores, and recommendations — so your sales team has context before the first call.
Measure what matters
Track views, completions, and lead conversion rates per tool. A/B test different content types to find what converts best for your audience.
Build custom tools for your business
Create your own calculators, quizzes, scorecards, graders, decision engines, and benchmarks with our drag-and-drop builders. Available on Growth and Agency plans.
Integrate with your CRM
Connect to HubSpot, Salesforce, Pipedrive, and 4 more CRMs. Leads arrive with their inputs, scores, and buying signals — no manual data entry.
Branded PDF reports
Every visitor can download a research-backed PDF report with your logo and branding. The email gate captures the lead before the download.
The results speak for themselves

Your brand, your leads
Having helped 2,400+ businesses embed interactive content, we designed these plans around what actually drives lead generation results. The Growth plan is our most popular because it unlocks the features — white-labelling, CRM webhooks, and A/B testing — that convert casual visitors into qualified leads.
Businesses that upgrade from Free to Starter typically see a 10–15x increase in lead capture within the first month. The difference is not traffic — it is the gated results, branded PDF reports, and CRM integration that turn tool completions into actionable leads.
