What is HeadsUp
HeadsUp takes product usage and customer data, models it into Customer 360 profiles, and surfaces conversion predictions so sales and growth teams know which accounts to act on and when. It sits at the intersection of product-led growth and sales, making it a fit for RevOps leads and GTM operators at SMB and mid-market companies running a self-serve or PLG motion. The standout capability is its predictive conversion engine — rather than relying on manual lead scoring, it uses behavioral signals from existing customers to flag the right time to sell. Companies like Netlify, Contentful, Dialpad, and Matillion have used it in this context. That said, HeadsUp is purpose-built for PLG companies; if your go-to-market is purely outbound or field sales with no product usage data to draw from, there is little here to work with.

Our verdict
Vanderbuild take
For RevOps and GTM leads running a product-led motion, HeadsUp is one of the more focused tools we've seen in the Sales Assistant category — it doesn't try to be a CRM or a sequencer, it just tells you which users are about to convert and when to reach them. On the agentic readiness front, there's no API available and MCP status is unknown, which means you can't drive this from an agent or wire it into an orchestration layer without scraping the UI — a real ceiling if you're building toward automated GTM workflows. Pricing is undisclosed publicly, so budget conversations will happen before you see a number. The honest limitation is structural: if your company doesn't have meaningful product usage data, the predictive engine has nothing to work with, and the tool loses most of its value.
