1. ConvertFlow
Best for: Home services companies that want qualifying quiz funnels and popups to book appointments and send leads to the right team.

ConvertFlow builds lead-qualifying quiz funnels, multi-step forms, popups and landing pages in one no-code builder. Answers and scores sync to HubSpot and other CRM integrations (Salesforce, Klaviyo, Customer.io etc), conditional logic sends each lead to the right outcome, calendar or quote, and the Scheduler element books calls through Calendly, Cal.com or HubSpot. Popups and page content can be personalized by location, ad source and earlier answers, and by CRM data on the Pro plan. A funnel can screen by service area and project, route qualified homeowners to the right calendar or a score-based quote range, and alert the right team. ConvertFlow has no dedicated calculator element, so estimates are built from scoring and conditional outcomes. ConvertFlow AI drives agentic funnel experimentation across the full funnel, with automated A/B testing for landing pages, popups, quiz funnels and site content.
