See every touch that led to the deal.

One path per buyer, from the first ad view to the closed deal.

View-through conversions

Source credits the ad a buyer saw but never clicked when that buyer later books a meeting or closes a deal. View-through sits next to click-through on the same path, so you can compare the two.

Outbound campaign tracking

Source records the UTMs and referrer on every visit, so tagged links in your outbound sequences land on the same path as ads and content. Add calls and meetings as offline touches, then ask which sequences sourced pipeline.

Organic keyword searches

Source pulls organic queries from Google Search Console and estimates which query brought in each contact, with a confidence score. See which searches turn into meetings and deals.

Multi-touch attribution

Every touch carries a weight for six models: first touch, last touch, linear, position based, and linear and exponential time decay. Switch models to see how credit moves between channels.

Ask where pipeline came from. Get the SQL with the answer.

Your agent finds the tables, runs the query and shows its work. Every answer includes the SQL behind it, so you can check how each number was calculated.

Teams who finally stopped arguing about attribution.

"Source caught a conversion I missed in Meta, on an ad I likely wouldn't have kept running. At our stage, those little insights matter a ton."

Ryan DoneyCEO, Pagedeck

"Source has the most intuitive, simple UI of any attribution product I've seen. The setup was fast."

Youssef KholeifFounder, Deviant Digital

"We’ve tried every enterprise attribution tool and never got the insights we were looking for. Source is able to get at the insights we can action on to drive growth."

Ethan BechtelCo-Founder & CEO, OhMD
