"Which channel produces the most revenue per dollar, not just leads?"
Revenue by source from ad platforms and HubSpot.
Connect every channel and your CRM once. Ask Claude or ChatGPT which channel actually drives pipeline, and where money is leaking.

I joined ad data from every channel with closed deals in HubSpot.
$284K closed revenue, and LinkedIn is underfunded
| Source | Leads | Revenue | Per lead |
|---|---|---|---|
| LinkedIn Ads | 11 | $112K | $10.2K |
| Organic search | 18 | $96K | $5.3K |
| Google Ads | 28 | $76K | $2.7K |
Key insight: LinkedIn brings 19% of these leads but 39% of revenue. Each LinkedIn lead is worth $7.5K more than a Google Ads lead.
I checked keywords, devices and placements in Google Ads.
$4,218 wasted, $3,680 of it fixable today
| Issue | Waste | Fix |
|---|---|---|
| Broad match "free CRM" | $1,840 | Add as negative |
| Mobile, 0% conversion rate | $1,120 | Bid adjustment -70% |
| Display Network leak | $720 | Exclude placements |
Why it matters: fixing these three frees enough budget for two more lead-gen campaigns.
I compared cost per lead and frequency for each campaign.
Pause one, refresh one, scale one
| Campaign | CPL | Freq. | Action |
|---|---|---|---|
| Retargeting, pricing page | $148 | 3.2 | Scale +$1.5K |
| Lookalike, top customers | $312 | 4.1 | Refresh creative |
| Broad interest, SaaS | $890 | 7.8 | Pause now |
Frequency alert: the broad interest campaign has been shown 7.8 times per person without converting. Pausing it saves $1,200 a month.

An AI marketing MCP is a connector that lets an AI assistant like Claude or ChatGPT read your marketing platforms and CRM together. It uses the Model Context Protocol (MCP), the open standard Anthropic introduced in 2024, so instead of stitching exports from six dashboards you ask one question in plain English and get an answer across every channel.
GrowthSpree's AI marketing MCP is a free, hosted server built for B2B and B2B SaaS teams. It connects Google Ads, LinkedIn Ads, Meta Ads, Microsoft Advertising, GA4, Search Console and HubSpot on one account, works in Claude, ChatGPT, Cursor or our web chat, and ships with 20 cross-channel prompts plus a prompt library for each platform.
Last updated September 21, 2026
Most AI marketing connectors are built for online stores chasing ROAS. B2B buys differently, whether you sell software, services or industrial products: long cycles, buying committees, demo and quote requests, and pipeline.
HubSpot sits next to every ad platform, so each answer can be judged on SQLs and revenue.
LinkedIn Ads and Microsoft Advertising sit next to Google Ads, Meta, GA4 and Search Console on one account.
Prompts look at 90-day windows, assisted conversions and demo or quote requests.
Prompts written from $60M+ of managed B2B ad spend and our LinkedIn Ads and Google Ads waste reports.
Every B2B channel on one account and one API key. Start with the channels you spend the most on, then add the rest.
Shopify is also available when your admin enables it.
Anyone can connect your data to an AI tool. Only GrowthSpree can tell you how your channels compare with other B2B companies. These numbers come from our Google Ads and LinkedIn Ads waste reports.
Benchmarks from GrowthSpree's published waste reports. Find the benchmark prompts in the prompt library below.
A connector gives an AI tool access to your data. That part is quickly becoming a commodity. What decides the quality of the answer is what the AI knows about B2B, and that is what GrowthSpree adds.
Your account is compared with 99 audited B2B SaaS accounts from our Google Ads and LinkedIn Ads waste reports, not with generic industry averages.
Prompts and playbooks encode how our operators run B2B accounts, from $60M+ of managed ad spend across 300+ companies.
LinkedIn Ads, Google Ads, Microsoft Ads, GA4, Search Console and HubSpot on one account, so answers are judged on SQLs and revenue.
Company context, saved prompts, scheduled audits and a Slack bot turn one good answer into a weekly habit.
Results from GrowthSpree agency engagements, the work these prompts and playbooks come from.
Every B2B marketer describes the same Monday morning. Here is what it looks like when you can just ask.
| The job | Today | With GrowthSpree MCP |
|---|---|---|
| Six tabs, no answer | Each platform shows its own numbers and none of them talk to each other. | Ask one question and Claude answers across every connected channel at once. |
| Budget bleeding silently | A campaign has been wasting $1,000 a month for three months. Nobody has had time to find it. | Ask "where am I wasting money?" and get exact amounts by channel, campaign and keyword, with fixes. |
| Wrong channel gets the credit | That "direct" conversion saw your LinkedIn ad, searched, got retargeted, then typed the URL. | Claude traces HubSpot deals back through every touchpoint so each channel gets fair credit. |
| HubSpot knows the truth | Your CRM knows which leads closed and for how much. Your ad platforms do not. | Claude joins ad data with HubSpot deals so you optimise for revenue, not MQL volume. |
| Reports eat your Fridays | Export, pivot, write the narrative, then redo it when the CEO changes the ask. | A board-ready marketing report across all channels, written in seconds. |
| Always a month behind | By the time you find the problem, the quarter is over. | Scheduled audits and a Slack bot surface problems while there is still time to act. |

Twenty minutes that replace a morning of dashboards.
Move money to what produces pipeline.
From six exports to one question.
The questions B2B and SaaS teams ask most once every channel is connected.
Each dashboard only sees its own data. Connected together, Claude can answer the questions that decide your budget.
Claude traces closed-won deals in HubSpot back through ad clicks, searches and site visits to show the real journey, not just the last click.
Example answer"68% of your closed-won deals had an organic search touchpoint as their first contact, but you attribute 80% of revenue to paid."
Google may bring 40 MQLs and LinkedIn 11. Claude joins ad data with HubSpot deals to show which one produced the revenue.
Example answer"LinkedIn brings 19% of leads but 39% of revenue. Each LinkedIn lead is worth $7.5K more than a Google Ads lead."
Not "consider reallocating budget". Claude compares cost per SQL, deal size and velocity by source and tells you where to move money.
Example answer"Moving $3,200 a month from Google Display to LinkedIn Sponsored Content is projected to add $34K in quarterly pipeline, based on your last 90 days of close rates by source."
Ask for this month's marketing report and Claude pulls every channel, writes the narrative and highlights wins and risks.
Example answer"Marketing generated $284K closed revenue this quarter. LinkedIn led with $112K. Watch: Facebook CPL is rising and retargeting needs a creative refresh."
"Which channel should get more budget next quarter?"
"Where is money leaking across our channels?"
"Which sources produce SQLs that close?"
"Which target accounts are engaging across channels?"
"Which client needs attention today?"
"What did marketing spend return last quarter?"
Google, Meta and HubSpot now publish official MCP servers, each for its own platform. Here is how the options compare for a B2B team that needs every channel and its CRM in one conversation.
| Best for B2B and SaaSGrowthSpree AI Marketing MCP | Official single-platform MCPs (Google, Meta, HubSpot) | Hosted multi-platform ad MCPs (e.g. Markifact, Adspirer, PaidSync) | Data platforms with MCP (e.g. Windsor, Supermetrics, Funnel) | |
|---|---|---|---|---|
| Price | Free to start | Free | Free tiers to paid plans | Usually paid plans |
| Platforms in one connection | Google Ads, LinkedIn, Meta, Microsoft Ads, GA4, Search Console, HubSpot | No, one platform each | Several ad platforms | Many sources |
| LinkedIn Ads | Yes | No official LinkedIn MCP | Varies by vendor | Varies by plan |
| HubSpot pipeline in the same chat | Yes | Separate server | Rare | Varies by plan |
| Setup time | About 5 minutes per platform | 30+ minutes each for the developer ones | Minutes | Hours, often with a data warehouse |
| Where you can use it | Claude, ChatGPT, Cursor, any MCP client, plus web chat on Premium | MCP clients | Usually Claude and ChatGPT | Varies by vendor |
| Scheduled audits to email or Slack | Yes: Google Ads and Meta | No | Some vendors | Dashboards and reports |
| Ready-made cross-channel prompts | 20 here, plus platform prompt libraries | None | Generic | Generic |
| Built for B2B and B2B SaaS | Yes | General purpose | General purpose | General purpose |
Official servers: Google Ads and Google Analytics (Google), Meta Ads (Meta) and HubSpot remote MCP (HubSpot). Competitor details come from each vendor's public pages in September 2026 and may change.
Almost anything a senior B2B marketing analyst, strategist and report writer would do with full access to every channel and your CRM. Here is what that covers, and what it deliberately will not do.
Hours saved every week, and budget leaks found that nobody knew about
"This tool has saved us hours each week. The real-time recommendations are spot-on, and we've plugged budget leaks we didn't even know existed."
Reporting went from a chore to a question
"GrowthSpree's AI platform has made reporting so easy. These custom reports are intuitive, and they've made decision-making so much faster."
Like a dedicated analyst, without the overhead
"From budget leaks to performance issues, it identified and fixed problems we didn't even know existed. It's like having a dedicated analyst, but without the overhead."
Data comes from each platform's official API through the access you approve on the platform's own consent screen. No scraping and no shared logins.
OAuth tokens are stored server-side and the AI never sees your password.
Every teammate gets a personal API key. Treat it like a password and ask us to reset it if it is ever exposed.
Disconnect any integration from the Integrations page, or revoke access from the platform's own settings. How data is handled is set out in our privacy policy.
Every connector has its own page with prompts, examples and setup details.
Still have a question? The MCP help center covers setup, integrations, plans and troubleshooting.
Get free accessAn AI marketing MCP is a connector built on the Model Context Protocol (MCP), the open standard Anthropic introduced in 2024, that lets an AI assistant like Claude or ChatGPT read your ad platforms, analytics and CRM. You ask questions in plain English and get answers from live data across every connected channel.
Google Ads, LinkedIn Ads, Microsoft Advertising, Google Analytics 4, Search Console and HubSpot CRM on the Basic plan, with Meta Ads, the GrowthSpree web chat and Slack on Premium. Shopify is available when your admin enables it.
You can start free on the Basic plan, which covers Google Ads, LinkedIn Ads, Microsoft Advertising, GA4, Search Console and HubSpot. Premium adds Meta Ads, the web chat and Slack.
No. Each platform is useful on its own from day one. The biggest gains come when an ad platform and HubSpot are connected together, because Claude can then judge campaigns on revenue instead of leads. Most teams start with their two or three biggest channels.
Each official server covers one platform. GrowthSpree connects every B2B channel, including LinkedIn Ads, which has no official MCP, and HubSpot on one account and one API key, so Claude can answer cross-channel questions like which channel produces the most revenue per dollar.
Native dashboards only see their own data. Google Ads does not know what happens in HubSpot after the click, and LinkedIn does not know which leads closed. With every channel connected, a question like which paid channel produces the most closed revenue per dollar becomes one question instead of a spreadsheet project.
On Claude's free plan, use the Claude Desktop extension. On a paid Claude plan or Cowork, add GrowthSpree as a custom connector. Developers can connect Claude Code with one command. For Cursor, Windsurf, ChatGPT and other MCP clients, paste the server config with your API key. Every option uses the same token from your dashboard.
About 5 minutes for the first platform: get your login by email, connect the platform and copy your token, add GrowthSpree to your AI tool, and ask. Each additional platform is one more click on the Integrations page.
Claude analyses your data and recommends specific changes with the reasoning and numbers behind them. You review and apply the changes in each platform.
Yes. GrowthSpree's MCP server is hosted, so it works with any client that accepts a remote MCP server: add it to ChatGPT as a custom connector, or paste the config into Cursor, Windsurf and other MCP clients. Claude has the most setup options.
No. On Claude's free plan you install the GrowthSpree extension in Claude Desktop and paste your token. Paid Claude plans and Cowork can add it as a custom connector instead, with higher usage limits for large accounts and long reports.
Yes. Automated Google Ads audits, and Meta Ads audits on Premium, run daily, weekly or monthly and are delivered by email or to a Slack channel, with your own report name and instructions.
Yes. Set your company context once, including what you sell, your ICP, goals and brand voice, and it is applied to every conversation so recommendations and copy fit your business.
Yes. Each teammate gets their own login and API key, and you can share any conversation through a private link. On Premium, the Slack bot answers questions for the whole team in your channels.
GrowthSpree uses your data to answer your questions and run the reports you set up. How it is stored and processed is set out in our privacy policy and your agreement with GrowthSpree. The AI assistant you choose, such as Claude or ChatGPT, also applies its own data policy.
A generic connector only gives an AI tool access to your data, which is quickly becoming a commodity. GrowthSpree adds what decides the quality of the answer: benchmarks from 99 audited B2B SaaS accounts, prompts and playbooks from $60M+ of managed B2B ad spend, every B2B channel plus HubSpot on one account, and workflow features such as company context, saved prompts, scheduled audits and a Slack bot.
The benchmarks come from GrowthSpree's two published waste reports: the $11.3M Google Ads Waste Report (43 B2B SaaS accounts, 36.1% average waste) and the 2026 LinkedIn Ads Waste Report (56 accounts, $9.4M audited, 32% average waste). Both are free to read on the GrowthSpree website.
Because B2B companies, SaaS or not, are measured on pipeline, not online sales. GrowthSpree puts LinkedIn Ads, Microsoft Advertising and HubSpot next to Google Ads, Meta, GA4 and Search Console, and its prompts look at SQLs, demo and quote requests, assisted conversions and 90-day windows.
B2B and B2B SaaS marketing leaders, demand generation and RevOps teams, agencies reporting across many clients, and founders who run their own marketing. That includes software companies and B2B firms in IT services, professional services and manufacturing.
Connect your platforms in minutes and ask your first question in Claude, ChatGPT or our web chat. If the answer does not show you something new about your marketing, you have lost five minutes.
