Attribution is broken. So we rebuilt it. One pixel across your GTM stack. Clicks, pages, meetings, deals. Including the ones that came from ChatGPT and Claude. If you've sat in a meeting arguing about what actually drove the pipeline, this is what we built. Source v2 is live. Demo video is below. Sign up for free: source.app

Source is now in Anthropic's Connectors Directory. If you use Claude, search for Source under Customize > Connectors, sign in, and ask your attribution data anything. Cost per conversion by channel, which pages book meetings, which campaigns close deals. Read-only, scoped to your sites. source.app/articles/source-i…

Your ads, CRM, Stripe, and website all report different revenue numbers. Parris wrote up how Source fixes that: one warehouse built around the contact, so true CAC by channel becomes a simple query instead of a quarter of CSV exports. source.app/articles/stop-sti…

Source MCP is live. Marketers can feed Claude, Cursor, Grok, and other agents multi-touch attribution from Source: the same Visit → Meeting → Deal path as the dashboard. Agents use that data to automate marketing workflows and drive more growth. Use it to: • Ship landing pages from paths that close deals • Reshape ad campaigns from cost per conversion • Build CRM follow-ups from Meetings and Deals that already convert • Triage channels against your CAC target • Queue blog topics and page rewrites from pages that book meetings source.app/articles/source-m…

View-through attribution credits an ad that was seen, not clicked, when a later meeting or deal happens. source.app/articles/view-thr…

B2B attribution and marketing attribution are not the same job. Marketing attribution scores the click. B2B attribution has to connect the visit, the meeting, and the closed deal. source.app/articles/b2b-attr…

B2B attribution has to connect the visit, the page, the meeting, and the closed deal. Last-click only sees the last one. source.app/articles/what-b2b…

Week of April 2, 2026 Updates We’ve officially migrated Source to a new, faster, and more reliable platform designed to deliver more accurate and stable marketing metrics. This release introduces a fully customizable funnel, deeper visibility into the end-to-end user journey, and a new set of interactive dashboard components including our AI-powered Smart Board (MVP). We’ve also expanded our integrations with support for Google Ads, Google Search Console, Meta Ads, HubSpot, Salesforce, and Calendly, with more on the way. On the data side, we’ve significantly upgraded our event tracking with improved pixel support, including page load events, form submissions, custom events (like stage updates), and server-to-server tracking. The new Source CRM enables user-defined funnels, CRM stage grouping, and unified funnel tracking across both browser and server-side events. New dashboard cards provide clearer insights into website, channel, and acquisition performance, while dedicated pages like User Journey and Explorer unlock deeper analysis. We’ve also introduced key platform improvements including multi-user account access, email-based invites and verification, multi-website support per organization, and an updated paid plan UI. Under the hood, our data pipelines now support all integrations and dynamically scaffold infrastructure based on pixel events, improving both speed and reliability. On the security front, we’ve completed all SOC 2 requirements and are entering the final observation window for full compliance. Additional upgrades include a scheduled penetration test, fully remediated Vanta alerts, deny-first permissions, and a zero-trust architecture across the platform.

Week of February 5, 2026 Changelog: We’ve shipped a new set of improvements focused on giving teams better visibility into their funnel, faster ways to explore performance, and a stronger foundation behind the scenes. This release introduces a new Customer Journey View (see attached screen) that makes it easier to understand how users move from first touch to conversion, along with deeper drill-down details on the Executive Dashboard’s Acquisition Performance card so you can see what’s really driving results. We’ve also added sort and search functionality to both Acquisition Performance and Channel Performance detail views, making it quicker to find the signals that matter. On the integration side, we’ve rolled out Zoho enhancements to improve reliability and data handling, alongside new welcome and “connect your pixel” emails to help teams get set up faster and avoid missing critical data. Behind the scenes, we’ve continued refining the attribution model, made steady progress on a broader database overhaul, and of course shipped the usual round of bug fixes and polish to keep everything running smoothly.

10/12/25 Changelog Updates: We’ve rolled out several key updates to improve reliability and user experience in Source. First, we implemented a quick but critical database fix, moving everything to a safer server to ensure stability. Cal.com and Calendly integrations can now be directly tied to specific stages, giving you more control over scheduling workflows. We also validated the “No CRM” option, which is now tested and working seamlessly end to end. On the integrations side, we resolved an issue with the Facebook connection button to make setup smoother. Finally, a series of UI improvements were made, including addressing the speed bump when deleting stages, to create a cleaner and more efficient user experience.
