Marketing teams are drowning in disconnected data. With campaigns running across Google Ads, Facebook, LinkedIn, TikTok, and dozens of other platforms, piecing together attribution and performance becomes an impossible puzzle of CSV exports and manual spreadsheet assembly.
Windsor AI promises to solve this chaos by connecting 325+ data sources to business intelligence tools and providing advanced marketing attribution, but their complex pricing tiers and specialized focus on marketing workflows often leave growing businesses needing more comprehensive solutions.
Understanding Windsor AI’s true costs and feature limitations—compared to versatile platforms like Coefficient—is crucial before committing to marketing-specific data integration subscriptions.
This guide breaks down Windsor AI’s complete pricing structure, reveals hidden complexities, and shows why thousands of businesses are choosing more powerful, transparent alternatives.
What is Windsor AI?
Windsor AI is a marketing-focused data integration platform that specializes in connecting advertising and marketing platforms to business intelligence tools, data warehouses, and spreadsheets. The company targets:
- Digital marketers
- Agencies
- Marketing teams needing consolidated campaign data and advanced attribution analysis
The platform offers connections to 325+ data sources with strong emphasis on advertising platforms like Google Ads, Facebook Ads, LinkedIn Ads, TikTok, and numerous other marketing channels. Windsor AI’s core differentiator lies in their marketing attribution capabilities, offering multi-touch attribution modeling to help businesses understand which marketing touchpoints drive conversions and revenue.
Major limitations for comprehensive business intelligence
Windsor AI’s marketing-centric approach creates significant restrictions:
- Limited scope – Excels at marketing data integration but provides minimal coverage for sales, finance, HR, or operational systems
- Additional tools needed – Teams often require multiple solutions to achieve complete business visibility
- Multiplied costs – Data silos and specialized tools increase software expenses substantially
Coefficient offers a broader approach with 70+ data sources spanning all business functions—marketing, sales, finance, and operations. While Windsor AI focuses exclusively on marketing attribution workflows, Coefficient provides comprehensive business intelligence with advanced AI capabilities, transparent pricing, and powerful automation that serves entire organizations.
The fundamental difference lies in scope and business impact: Windsor AI serves marketing-specific needs with specialized attribution features, while Coefficient empowers complete business intelligence workflows with advanced automation, AI assistance, and broader data ecosystem coverage at more affordable pricing.
Windsor AI pricing plans overview
Windsor AI uses a tiered subscription model based on data source limits, account capacity, and destination restrictions. Their pricing structure reflects their marketing focus, with plans designed around the number of advertising accounts and marketing platforms teams typically manage.
Key pricing characteristics:
- Data source quantity focus – Emphasizes connection limits over feature sophistication
- Capacity-based limitations – All 325+ sources available but restricted by usage limits
- Destination restrictions – Output limitations vary by tier
- Two-tiered system – Basic data integration and advanced attribution require separate subscriptions
Windsor AI also offers specialized attribution pricing for advanced marketing attribution features, creating scenarios where teams need both subscriptions. This separation can double costs for comprehensive marketing analysis needs.
Annual billing provides significant discounts (typically 15-20% savings), but the capacity-based model creates scaling challenges as marketing programs grow. Teams often discover they need higher tiers than initially expected.
Windsor AI free plan
What’s included
The Free plan provides basic functionality for testing or managing very simple marketing scenarios:
- 1 user access – Individual user limitation
- 3 data sources – Access to any of 325+ available integrations
- 15 accounts total – Maximum accounts across all data sources
- 5 destination tasks – Limited output destinations
- Daily scheduled sync – Once-daily automated refreshes
- 30-day history limit – Limited historical data access
- 30-day trial period – Time-limited full feature access
Who it’s for
The Free plan suits individual marketers or very small businesses testing Windsor AI’s capabilities. However, the 15-account limit becomes restrictive quickly—a typical marketing setup might need Google Ads (5 accounts), Facebook Ads (3 accounts), LinkedIn Ads (2 accounts), plus analytics platforms, rapidly consuming the allocation.
Limitations
The account-based limitation model creates confusion and scaling issues. Users often underestimate account requirements, especially when managing multiple clients or business units. The 30-day history limit eliminates meaningful historical analysis or trend identification capabilities.
Coefficient’s Free plan offers 3 data sources with 50 automated refreshes monthly and full historical access, providing more practical value for teams evaluating data integration solutions without artificial account restrictions.
Windsor AI basic plan
Pricing & features
The Basic plan costs $23/month (or $19/month billed annually) and targets small teams with moderate marketing data needs:
- Unlimited users – No team size restrictions
- 3 data sources – Same source limit as Free plan
- 75 accounts – Substantial increase in account capacity
- 5 destination tasks – Same destination limitations as Free
- Daily scheduled sync – Once-daily automated refreshes
- 5M MAR included – Monthly active rows for data warehouse usage
- Additional data – $20 per 1M additional rows
Best use cases
Small marketing teams managing moderate advertising spend across a few platforms might find the Basic plan sufficient. The unlimited users feature provides value for small agencies or teams needing collaborative access to marketing data.
Value analysis
At $23/month for 3 data sources, the Basic plan appears competitive until you consider the destination task limitations. Most marketing teams need data in multiple formats—Google Sheets for analysis, Data Studio for dashboards, and perhaps BigQuery for advanced analytics—potentially consuming the entire allocation.
Coefficient’s Starter plan at $49/month includes 3 data sources with unlimited destinations and advanced AI capabilities, providing more comprehensive value despite higher headline pricing.
Windsor AI standard plan
Pricing & features
The Standard plan costs $118/month (or $99/month annually) and represents Windsor AI’s most popular tier:
- Unlimited users – Full team collaboration
- 7 data sources – Moderate increase in source capacity
- 75 accounts – Same account limit as Basic
- Unlimited destination tasks – No output restrictions
- Daily scheduled sync – Once-daily refresh frequency
- 10M MAR included – Higher data warehouse allowance
- Additional data – $20 per 1M additional rows
Target market
Mid-size marketing teams or small agencies managing diverse advertising campaigns typically choose the Standard plan. The unlimited destination tasks eliminate output bottlenecks while 7 data sources accommodate most marketing tech stacks.
Cost comparison
At $118/month, the Standard plan costs significantly more than alternatives while still maintaining daily-only refresh limitations and account restrictions. Teams may find the pricing difficult to justify without advanced attribution features included.
Windsor AI plus plan
Pricing & enhanced features
The Plus plan costs $298/month (or $249/month annually) and targets larger marketing operations:
- Unlimited users – Full team access
- 10 data sources – Higher source capacity
- 200 accounts – Substantial account increase
- Unlimited destinations – No output restrictions
- Daily scheduled sync – Still limited to daily refreshes
- 25M MAR included – Higher data allowance
- Additional data – $20 per 1M extra rows
When to consider plus
Large marketing teams, agencies with significant client portfolios, or enterprises with complex advertising ecosystems might justify the Plus plan investment. The 200-account limit accommodates substantial marketing operations while 10 data sources handle most comprehensive setups.
Cost analysis
At nearly $300/month, the Plus plan represents significant investment while still lacking real-time or hourly refresh capabilities. Teams must evaluate whether marketing-specific features justify the premium over comprehensive business intelligence alternatives.
Windsor AI professional plan
Pricing & advanced features
The Professional plan costs $598/month (or $499/month annually) and targets enterprise marketing organizations:
- Unlimited users – No restrictions
- 14 data sources – High source capacity
- 500 accounts – Substantial account management
- Unlimited destinations – Complete output flexibility
- Hourly scheduled sync – Finally introduces more frequent refreshes
- 50M MAR included – High data warehouse allowance
- Account manager – Dedicated customer success support
- Advanced support – Priority assistance
Enterprise benefits
Large enterprises benefit from hourly refresh capabilities, dedicated support, and massive account capacity. The plan accommodates complex, multi-brand marketing operations while providing premium customer success resources.
Investment considerations
At nearly $600/month, the Professional plan requires substantial justification through significant marketing operations and attribution analysis requirements. Organizations must carefully evaluate ROI versus comprehensive business intelligence alternatives.
Windsor AI attribution pricing
Windsor AI offers separate attribution-specific pricing tiers that add substantial costs for teams needing advanced marketing attribution features:
Attribution standard plan
- $658/month (or $549/month annually)
- Unlimited visits and users
- Multi-touch attribution capabilities
- 1 analytics data source + up to 3 total sources
- Export to 2 data destinations
Attribution professional plan
- $838/month (or $699/month annually)
- Enhanced attribution features
- 2 analytics sources + up to 7 total sources
- Export to 5 destinations
- Dedicated account manager
These attribution-specific plans often double total costs for teams needing both data integration and attribution analysis, creating expensive scenarios that many businesses find difficult to justify.
Hidden costs and considerations
Windsor AI’s marketing-focused approach and capacity-based pricing model create several hidden costs and scaling challenges that surprise users during implementation and growth phases.
Account-based scaling surprises
The account limitation model creates unexpected costs as marketing operations grow:
Stop exporting data manually. Sync data from your business systems into Google Sheets or Excel with Coefficient and set it on a refresh schedule.
Get Started
- Multi-account platforms – Each Google Ads, Facebook Ads, or LinkedIn account counts separately toward limits
- Client growth – Agencies adding clients quickly exhaust account allocations
- Campaign expansion – New advertising platforms or account structures consume capacity
- Testing environments – Separate accounts for testing may push teams into higher tiers
Data warehouse overage costs
Windsor AI charges $20 per 1M additional monthly active rows (MAR) for data warehouse usage, which can create significant overage charges:
- Large advertising accounts – High-volume campaigns generate substantial data
- Historical imports – Backfilling data consumes MAR allowances quickly
- Multi-platform reporting – Combining data from many sources increases row counts
- Detailed attribution – Granular tracking multiplies data volume requirements
Specialized attribution costs
Teams needing advanced attribution features face double subscription scenarios:
- Separate attribution pricing – Attribution plans start at $549/month additional
- Limited integration – Attribution features don’t integrate seamlessly with basic data plans
- Complex setup – Attribution implementation may require professional services
- Ongoing optimization – Attribution model tuning may need continued consulting
Limited scope requirements
Windsor AI’s marketing focus often necessitates additional tools for complete business intelligence:
- Sales data integration – CRM and sales platform connections remain limited
- Financial system connections – Accounting and finance data requires separate solutions
- Operational metrics – Inventory, customer service, and project data need other platforms
- HR and employee data – People analytics require additional specialized tools
Coefficient’s comprehensive alternative: Coefficient eliminates these hidden costs through transparent, user-based pricing that includes comprehensive data source access, unlimited row processing, and advanced AI capabilities without capacity restrictions or specialized attribution surcharges.
