Researched and fact-checked by Bartu Cavusoglu · Updated October 26, 2026
Windsor.ai is a no-code data integration platform that automatically collects data from more than 350 business platforms and delivers it to the tools where teams analyze it. Its focus is marketing and sales data, with sources such as Facebook Ads, Google Ads, GA4, LinkedIn Ads, Salesforce and Shopify.
The company was founded in 2017 by Niklas Kolster, a former data scientist at Accenture and eBay, who started it in Zurich. The site describes the team as global data engineers and analysts, and states that the product is made in Switzerland.
Windsor.ai positions itself as a replacement for CSV exports, copy-paste work and custom API scripts. It describes itself as an ETL/ELT platform that handles schema mapping, updates and near real-time syncs.
Setup follows four steps described on the site. A user creates an account, connects data sources through Windsor.ai connectors, chooses a destination, and optionally connects the data to an AI chat such as ChatGPT or Claude.
Destinations fall into two groups. BI destinations such as Looker Studio and Power BI sync without limits on every plan. Scheduled destination tasks write tables to Google Sheets, BigQuery, Snowflake, Amazon S3, Redshift, Azure SQL, Azure Blob Storage, PostgreSQL, MySQL and Databricks.
Refresh frequency depends on the plan: daily on Basic, daily or hourly on Standard and Plus, and down to every 15 minutes on Professional. Backfills load historical data into a table. The preview table cache refreshes every 6 hours unless cleared manually.
The core of the product is its connector library of 350+ sources, which can be blended into a single dataset. The site says every plan includes access to all data sources and destinations, so tiers differ by limits rather than by which connectors are available.
Windsor MCP is the newest addition. It connects Windsor.ai data to Claude through a native connector, to ChatGPT through a native app, and to other LLMs, including Copilot, so users can ask questions about cross-channel performance in chat. It is included in all plans.
Other capabilities include a template gallery with dashboards for Looker Studio, Power BI, Excel, Google Sheets and Tableau, external authentication through a shareable auth link, and an auto-add accounts feature on Professional designed for agencies.

It supports 350+ data sources such as Facebook Ads, GA4, Google Ads, LinkedIn Ads and Salesforce. Destinations include Looker Studio, Power BI, Google Sheets, Excel, Tableau, BigQuery, Snowflake, PostgreSQL, MySQL, Amazon S3, Redshift, Databricks and AI chats such as Claude and ChatGPT.
Yes. Windsor MCP connects Windsor.ai data to Claude through a native connector and to ChatGPT through a native app. The site says it also works with other LLMs, and Windsor MCP access is included on all plans.
The site targets analysts automating reporting, agencies managing many client accounts, and data teams that want managed pipelines instead of custom scripts. Agencies get unlimited users and data blending on every plan.
A data source is a platform such as Google Ads, and an account is one account ID inside it, such as one Google Ads account or GA4 property. Plan limits on accounts are totals across all sources. Facebook Ads, Facebook Pages and Instagram each count as one data source.
Scheduled syncs run daily on Basic, daily or hourly on Standard and Plus, and daily, hourly or every 15 minutes on Professional. The preview table cache refreshes every 6 hours unless cleared manually.
