Rebuilding Go-To-Market Around Product Telemetry
Earl Lee, co-founder and CEO of HeadsUp, on the modern data stack value chain
This points to a shift in where go-to-market software starts, from the CRM record to the product event stream. In a product led motion, the first useful signal is not that a rep logged a lead, it is that a user signed up, invited teammates, hit a usage threshold, stalled in onboarding, or showed expansion behavior. That changes the core workflow, which becomes deciding who to help, when to step in, and what action to trigger across sales, growth, and success.

Traditional CRM stacks were built for top down selling, where reps create opportunities, move stages, and forecast deals. Product led companies need systems that can read warehouse and app telemetry, score accounts from usage, and route the right users into email, chat, or rep outreach. That is why tools like Calixa and HeadsUp sit closer to the warehouse and product data than classic CRM workflows.

The practical change is organizational as much as technical. Product led teams often split the journey between fully automated conversion for users who will buy on their own, and sales assist for accounts that need a human to unlock a bigger contract. That blurs the line between sales and customer success, because both are working from the same usage signals and trying to push users toward value.
-
The opportunity is large because incumbents carry old assumptions. Salesforce itself describes product led sales as a model where users engage with the product first and sales uses usage data to convert and expand them, but older CRM architectures still center on rep entered records. Rebuilding the stack means making product telemetry, automation, and next best action native, not bolted on through separate BI and sync layers.
Over time, the winning go-to-market systems will look less like digital pipeline trackers and more like customer operating systems. They will watch live product behavior, identify the moment a self serve user hits a ceiling, and trigger the right mix of automation and human help. That is the opening for new platforms to take workflow share from legacy CRM, even if they coexist with it for years.
