• Flint automatically analyzes your site and extracts key elements of your design system, including colors, typography, spacing, visual patterns, and component styles
• Existing HubSpot pages migrate through full-page screenshots pasted into Flint chat, then refined section by section
• HubSpot forms can be embedded on Flint pages, or Flint can build a native HTML form that submits to a HubSpot endpoint or API
• According to Flint's case study, LangChain built 17 keyword-targeted pages in roughly two hours and generated six figures in pipeline within about six weeks
• Flint reports that Graphite saw a 50%+ conversion rate increase in Google Ads and influenced more than seven figures of ARR over ten months

Why Your Paid Campaigns Need a Faster Layer

HubSpot CMS excels at content management, marketing automation, and customer lifecycle tracking. But when marketing teams need rapid landing page deployment for paid campaigns, template customization work can compound with scale.

Before You Start: Pre-Migration Checklist

This isn't a full CMS migration. You're identifying which pages benefit from Flint's speed advantage.

Step 1: Sign Up and Import Your Brand

Sign up for Flint's 14-day free Basic trial, which requires no credit card. Basic starts at $500 per month after the trial and is aimed at brands spending under $10K per month on ads, with Enterprise available at custom pricing.

When you provide your website URL, Flint automatically analyzes your site and extracts design tokens and visual patterns to establish a design system for new pages. Flint crawls the homepage and key pages, capturing:

• Colors and palette relationships
• Typography, font weights, and size hierarchies
• Spacing, border radius, and shadows
• Button and link styles
• Header and footer patterns, plus component templates matching your site's visual language

Review the imported pages and refine the design where necessary using Flint's design system and editing workflows. Extraction quality determines output quality for every subsequent page, so it is worth checking carefully before generating at volume. If important patterns live on interior pages rather than the homepage, supply those as additional references.

Step 2: Recreate Your Existing HubSpot Landing Pages

Screenshot-based migration is the documented path for moving pages you already have.

1. Take a full-page screenshot of the HubSpot landing page you want to move
2. Paste it into Flint's chat interface with context about the page's purpose
3. Flint generates a brand-consistent version using your imported design system
4. Refine it section by section in chat until it matches what you need

Work through your priority list from the checklist rather than migrating everything at once. Starting with conversion-driving pages gives you a real performance comparison early.

Step 3: Generate New Campaign Pages

Flint supports several page generation workflows, including conversational prompts, screenshot-based recreation, spreadsheet and CSV-driven bulk generation, and MCP or API-connected data sources.

For a new page, describe what you need in natural language, review the generated layout, then refine. Pages can be refined through Flint's editor or conversationally through supported AI workflows, so non-technical team members can adjust copy, CTAs, images, and sections without pulling in developers.

Built-in CRO capabilities mean Flint's agents are trained on the latest best practices of conversion rate optimization. Flint is designed to help teams create and optimize campaign pages for conversion, including testing messaging, layouts, and CTAs. Actual conversion performance should be validated through testing rather than assumed.

Flint supports creating landing page variants for A/B testing, including testing messaging, visual treatments, and CTA placement, with documented integrations for VWO, Optimizely, and Statsig. Flint's Graphite case study documents testing hero treatments and CTA placement this way.

Step 4: Connect Analytics and Route Forms to HubSpot

Set this up before you publish, so you have clean data from the first campaign.

Flint supports carrying over existing analytics setups. Depending on the setup, scripts may be detected during site import or re-added through Site Settings. Flint's migration documentation instructs users to reconnect integrations after migrating, so treat this as a real step rather than something that happens automatically:

1. Google Analytics: Enter your GA4 Measurement ID in Site Settings, after which Flint injects the script into published pages
2. Google Tag Manager: Enter your GTM Container ID
3. Segment and custom scripts: Flint supports Segment and arbitrary custom scripts alongside the documented GA4 and GTM setup

For forms, Flint does not have native forms yet. Your options are:

• Embed your existing HubSpot form on the Flint page
• Have Flint build a native HTML form that submits to a HubSpot endpoint or API, which gives you full brand control over styling
• Submit to a custom HTTP or webhook endpoint for custom workflows, including Zapier endpoints as part of a larger automation

Test form routing with dummy submissions before launching live pages, and confirm records land in HubSpot with the right properties mapped.

Step 5: Configure Your Domain and Publish

Domain configuration depends on whether you're publishing to a root domain, subdomain, or subpath. Follow Flint's domain-specific setup instructions rather than assuming one pattern covers all cases.

• Root domains can be configured automatically with Entri, or manually with the A and TXT records Flint supplies
• Subdomains such as pages.yourdomain.com follow a separate setup workflow
• Folders or subpaths such as yourdomain.com/campaigns/ are supported for compatible infrastructure configurations, and generally require reverse proxy setup
• Flint preview URLs let you test before making DNS changes

DNS propagation usually takes 15 to 30 minutes but can take up to 48 hours. Flint provisions SSL automatically once the domain is configured.

A hybrid deployment leaves the existing HubSpot site's URLs and content architecture unchanged while adding Flint-hosted campaign pages, which keeps your marketing automation workflows and blog management exactly as they are.

Step 6: Scale Into Programmatic Generation

Once individual pages work, move to bulk. This is where Flint's value compounds.

Flint MCP connects Flint with Claude Cowork and Claude Code for programmatic landing page creation and management, including reading the brand, creating pages, customizing them, and publishing. Flint supports programmatic workflows involving Claude, Airtable, Clay, Relay.app, APIs, CSVs, and CRMs.

With these workflows, you can:

• Create pages directly from Claude through natural conversation
• Build pages from Clay enrichment data, using an instruction like "Create 50 ABM pages from my Clay list"
• Orchestrate bulk creation from spreadsheets or databases that Claude can access
• Trigger page generation from CRM-connected workflows using supported automation tools such as Relay.app, which has documented workflows for follow-up pages and auto-pages for new CRM records

Flint reports that Amigo created 341 tailored account-based pages in five minutes using programmatic generation.

Step 7: Configure SEO and Measure Results

Flint says its pages include technical SEO and GEO foundations such as server-side rendering, robots.txt configuration, sitemap support, semantic HTML, image optimization, and llms.txt. Flint provides production-oriented SEO and publishing infrastructure for its pages, which means less of the technical checklist typically falls to your team after launch.

Flint includes technical foundations intended to support discoverability in AI answer engines such as ChatGPT, Google AI Overview, Perplexity, and Claude. Flint reports that Modal and Windsurf pages achieved top rankings for targeted queries in Google and AI search, though those placements were specific to the queries and time periods those teams tracked. Technical optimization supports discoverability rather than guaranteeing placement.

For measurement, compare against the HubSpot baseline you exported in the checklist. Track conversion rate changes by traffic source, form completion rates, bounce rate, and time to conversion. Run variants through your experimentation platform, since Flint generates the variants and the testing tool measures them.

Why Flint Makes Sense for Campaign-Heavy Marketing Teams

Marketing teams evaluating landing page solutions should consider Flint for campaign-specific use cases where speed directly affects revenue.

Flint's MCP and API are designed to make high-volume, AI-assisted page generation workflows easier to orchestrate. You can create pages from Claude conversations, trigger generation from CRM-connected workflows, or build in bulk from enrichment data. That shifts landing pages from a bottleneck toward a repeatable process.

Flint describes its pages as production-ready, with custom domain publishing and support for analytics and testing tools. Combined with Flint's SEO and GEO-oriented infrastructure, pages can be published with core technical foundations already in place.

Reported customer outcomes are worth reviewing, with each figure specific to that company's circumstances:

• Graphite case study: 50%+ conversion rate increase in Google Ads and more than seven figures of ARR influenced over ten months, plus four comparison pages that ranked first in AI search within 48 hours
• 11x case study: 3x conversion rate on comparison pages relative to homepage traffic
• LangChain case study: six figures in pipeline within about six weeks, from 17 pages built in roughly two hours
• Forus case study: roughly 3x paid media conversions while saving more than 70 hours of manual work
• Amigo: 341 tailored account-based pages created in five minutes

Teams may choose to retain HubSpot for blogs, email marketing, automation, and customer lifecycle workflows while using Flint for campaign landing pages. For B2B SaaS and AI companies running paid campaigns, that combination covers both robust content management and high-velocity campaign page deployment.

Flint offers a 14-day free trial requiring no credit card, and you can book a demo to scope a pilot on your own site.
