Leadsie

Leadsie solves the agency-client handoff problem: you build a lead capture form, your client's website needs it, but they won't give you FTP or CMS access. Leadsie's snippet works on any site—WordPress, Shopify, Webflow, or static HTML—and captures leads directly into your CRM.

What it does

Leadsie provides a JavaScript snippet that agencies embed on client websites. The snippet renders a customizable lead capture widget that sends submissions to the agency's CRM (HubSpot, Salesforce, Mailchimp, etc.). The widget is white-labeled, so clients see the agency's branding, not Leadsie's. No client-side code changes needed beyond pasting the snippet.
