G2 user
"Extremely intuitive and easy platform for data transformation and reporting"
We needed a tool that could easily take client media data and turn it into clean, informative reports that clearly show the data. Funnel does exactly that.

Betül
"Funnel makes my daily life easier"
Easy to navigate, fast support, so many connection options, currency management, multiple data export options.
“We were relying on Supermetrics to feed Google Sheets, which we then transformed and connected to Looker Studio. The data refreshes were constantly breaking, and the process was not efficient at all.”
Director, Business Analytics

“The Supermetrics API used to go out all the time and would cause all of our reporting to crash. We would have to reconnect everything.”
VP of Media Management

When windsor.ai is the right choice, and when Funnel is better
Move data fast at low cost
Windsor.ai is a good fit when you need an affordable, self-serve way to pull data from a handful of marketing platforms into a destination like Looker Studio, Google Sheets, Excel or Power BI. Public pricing, a free trial and all destinations included make it easy to start with a small, single-source setup.
Build a marketing data foundation
Funnel is the better fit when marketing data has to be trusted across teams, clients, markets, dashboards, warehouses, measurement and AI tools. Each of them draws from one governed source, so the numbers hold up as you add channels, markets and clients.
Get your data where you need it
Collect data from more than 600 marketing data sources and get it where you need it with solid connectors that won’t let you down. Discover all our data source connectors below.
FAQ
With a connector tool like Windsor, the LLM uses the connector to pull the data, one source at a time, when you ask. There's no organized layer in between, so the model has to work out what everything means on the fly: which fields to grab, what a metric refers to, how one platform lines up with another. It does its best and answers confidently, but it's interpreting raw platform data in the moment.
With Funnel, the AI reads from data you've already collected, stored, and organized. The definitions your team agreed on, the history, the context around each number, which market and currency it belongs to, are all there before you ask a single question. So when ChatGPT or Claude queries Funnel through our MCP, it's working from the same trusted numbers your team already reports on, not a live guess at raw data.
