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.

Best for

Leadsie is ideal for digital marketing agencies managing lead generation for multiple clients, web developers who need to add lead capture without modifying client infrastructure, and sales teams that want to embed forms on partner or affiliate websites. It is NOT for solo entrepreneurs who only need a simple contact form on their own site.

Use cases

Agencies use Leadsie to quickly onboard client websites without back-and-forth over access credentials. Developers embed the snippet on any platform without touching the client's codebase. Sales teams create branded forms for partner sites and capture leads directly into their CRM.
