Windsor.ai is a tool that helps businesses track their marketing and see how well different channels and campaigns are doing. It’s useful for companies that want to know which marketing strategies are most effective.

But does it really do what it says?

In this Windsor.ai review, let's take a look at its features, pros, and cons to help you decide if it’s the right tool for your business.

All About Windsor.ai

Windsor.ai is a no-code data integration platform that connects marketing, sales, CRM, e-commerce, and analytics tools to automatically gather data.

This data can be sent to places like spreadsheets, BI tools, data warehouses, or AI chats. Users can create data pipelines quickly without needing to write any code. Setup is fast and usually takes just a few minutes.

Founded in 2017 by Niklas Kolster in Zurich, Switzerland, Windsor.ai grew out of his frustration with linking different data sources and getting clear insights. Before starting the company, Niklas worked as a data scientist at Accenture and eBay for over ten years.

His goal was to simplify data handling for businesses and help them focus more on decision-making.

Windsor.ai now connects to over 325 sources, including ad platforms like Google Ads, Meta Ads, and TikTok Ads, as well as tools like Google Analytics, HubSpot, and Salesforce. Data is updated on a set schedule, only loading new information to stay efficient.

The company started as a one-person project and has grown to a team of around 30 people, serving over 5,000 customers in 120+ countries. Windsor.ai offers both free trials and paid plans to suit different business needs.

Products Offered by Windsor.ai

Windsor.ai provides simple tools to gather marketing, sales, and e-commerce data from multiple sources and send it wherever you need.

The main product is a no-code data connector and ETL/ELT platform. It automatically pulls data from over 325 sources, including ad platforms like Google Ads, Meta Ads, LinkedIn Ads, and TikTok Ads, as well as analytics tools like Google Analytics, CRMs like HubSpot and Salesforce, and e-commerce systems like Shopify.

You can send this data to different destinations without needing to write any code. Popular destinations include:

• Spreadsheets like Google Sheets.
• BI tools like Looker Studio, Power BI, and Tableau.

• AI chat platforms using Windsor MCP (Marketing Connector Platform) for tools like ChatGPT, Claude, Gemini, or Perplexity.

Another important feature is marketing attribution, which shows which channels and campaigns are driving conversions and sales. This helps teams understand the customer journey and improve ROI.

The platform includes basic data transformations, automatic normalization, schema matching, scheduled syncs, and monitoring to keep data clean and up-to-date.

All these features are available in one main service with different plans based on your needs, such as the number of sources, accounts, sync speed, and data volume. A free trial and a limited free plan allow you to test the tool before committing.
