Primer is positioning itself as the bridge that lets B2B marketers run campaigns on B2C-scale channels like Meta, Reddit, YouTube, and DV360 with B2B-grade precision, while also tightening targeting on channels such as LinkedIn and Google that already serve B2B advertisers, using CRM and de-anonymized site data instead of manual list uploads, and pairing every campaign with control-group incrementality measurement rather than click-based attribution alone. Independent conversation about the platform is still early, a quieter footprint so far relative to its customer roster.

Business Profile
Primer was founded in San Francisco in 2019 by Keith Putnam-Delaney and Juan Vasquez and raised a $12 million Series A led by Craft Ventures, with Slack Fund and Salesforce Ventures also participating. Since then the company has built in two directions, audience targeting from CRM and de-anonymized site data on one side and incrementality measurement on the other, and has kept shipping steadily, adding a HubSpot integration, a historical win-rates feature, form-based retargeting, and an expanded audience database. Customers span demand-gen, ABM, and PLG-motion teams at companies including Rippling, Verkada, and Confluent.
Agent Readiness
Measures how easily your agents can build on it — API, MCP, CLI, SDK, docs depth. Methodology →
Primer's public site and documentation don't list a developer API, SDK, or MCP integration — no public agent surfaces on file yet. What is public are its sync integrations into ad platforms and CRMs (LinkedIn, Meta, Google, Reddit, DV360, HubSpot, Salesforce), which move campaign and audience data rather than serving as an entry point for outside agents.
