In short_
Leadpages helps marketers create and optimise landing pages, collect leads and connect them to a CRM. Its current platform includes AI building, visual editing and conversion-testing tools.
ConvertSite builds interactive sites and pages that work for your business. Calculators, configurators and quote flows connect customer inputs to an answer or offer. The whole interactive flow uses native building blocks. Your team edits pages, formulas and conditions in a visual DIY builder, with analytics, funnels and A/B testing built in.
The difference is what you need the site to do: capture interest, or help each visitor work out what to buy.
In short_
Outgrow is a content marketing platform built for lead generation campaigns: quizzes, assessments, ROI calculators that attract and capture contacts.
ConvertSite is built for businesses that need to qualify buyers, show real-time pricing, and close sales without a sales call.
If you sell something with variable pricing or complex configuration, ConvertSite is purpose-built for that. If you're running content campaigns and need branded quiz funnels at scale, Outgrow has the depth.

What's missing_
The feature Leadpages does not have
A campaign page can collect an enquiry. An interactive site can help the visitor work out the offer first.
In ConvertSite, measurements, options and answers feed into editable formulas and conditions. Change a minimum charge, add a service option or show a follow-up question from the same visual builder that manages the page. Built-in analytics, funnels and A/B testing help you improve the same journey.
Leadpages already provides visual page and form editing. The distinction is direct visual control over calculation and quote-flow logic, rather than maintaining that interaction in custom code or a separate tool.
What a customer actually experiences
A visitor completes your pricing calculator, sees their quote on screen, then immediately receives a branded PDF proposal in their inbox: itemised, on-brand, and ready to share with their team. No manual follow-up. No "we'll send a quote within 24 hours." The sale moves faster because the buyer has everything they need the moment they finish the tool.
