Growth7 vs HubSpot Marketing Studio and Breeze Agents: A Side-by-Side Comparison

October 24, 2026 · 5 min read · By Justin Pennington

HubSpot's Marketing Studio and its Breeze marketing agents (Campaign, Content and Nurture) are now in public beta. Growth7 also lets you describe a marketing goal and have the software do the work. They get there in different ways, at different prices, with different assumptions about where your customer data lives.

This is a side-by-side comparison, using each company's published pages as of October 24, 2026. Where we couldn't confirm something on HubSpot's public pages, we say so instead of guessing.

Price: a tier plus credits, or a plan with AI included

HubSpot's Marketing Studio FAQ is direct: you need Marketing Hub Pro or Enterprise, and Campaign Agent, Content Agent and Nurture Agent consume credits. Professional is listed at $890/month with 3,000 HubSpot Credits. HubSpot's catalog prices Content Agent at 1,000 credits per piece of content, so the included credits go further on nurture personalization (10 credits per email) than on content generation. You can set limits per feature, buy capacity packs, or pay as you go at $0.010 per credit.

Growth7 bundles a dollar amount of AI usage into each plan and bills anything beyond it as it's used, with a record of what it went on. Neither model is free AI. The difference is how you budget for it: HubSpot counts in credits on top of a tier, Growth7 counts in dollars inside your plan.

The CRM question

This is the biggest structural difference.

Marketing Studio is part of Marketing Hub. Its agents work from what HubSpot knows about your brand, contacts and past campaigns. That's an advantage if HubSpot is already your CRM and full of good data.

Growth7 starts from the other side. If your team runs on Salesforce, Pipedrive or Zoho CRM, or on HubSpot Starter, you connect it with the CRM's own sign-in and keep working there. Growth7 reads contacts, companies and pipeline stages, runs the outreach, and writes opens, clicks, replies, texts, calls and lead score back onto the contact. No export, no second database, and no change of CRM.

Channels

Studio is strongest at planning and producing campaigns inside HubSpot: plans, content, nurture emails and the automation on one canvas, with links to work you run on outside channels.

Growth7 runs the outreach itself across email, SMS, AI voice and social from one campaign, as toggles on the same audience, and reports spend and performance from your ad accounts alongside it. One login covers all of them.

Which to choose

Choose HubSpot Marketing Studio if you're already on Marketing Hub Professional or Enterprise, your data lives in HubSpot, and you want planning and content agents inside the tool you already pay for.

Choose Growth7 if your CRM is Salesforce, Pipedrive, Zoho or HubSpot Starter and you don't want to migrate or move up a tier, or if you want email, SMS, AI voice calls, social and ads run from one place with your CRM kept in sync.

Start on Growth7: self-service sign-up with plans from $500/month. Or book a demo and we'll run it against your own market.

Checked against public pages on October 24, 2026. Marketing Studio and HubSpot's marketing agents are in public beta, and both companies' pricing can change, so confirm on the source pages before you buy.
