Tofu is positioning itself as an agentic campaign system for B2B marketers, moving from personalized content production into CRM data quality and paid-media execution. Its footprint is early, with current practitioner conversation touching broader AI deployment across revenue teams rather than detailed product workflows. Recent company work centers on Ads Agent, which turns a brief and CRM data into matched audiences, creative variations, and launch-ready campaigns for LinkedIn Ads and Google Ads. That extends Tofu’s role from generating campaign assets to assembling more of the operating workflow around them.

Business Profile
Tofu was founded in 2023 in San Mateo by CEO Eunjoon Cho, engineering lead Honglei Liu, and CRO Elaine Zelby, who also holds a Venture Partner seat at SignalFire. The company has raised $17M across two rounds, a $5M seed led by Index Ventures and a $12M Series A led by SignalFire with HubSpot Ventures participating, closing in February 2025, and funding has stayed flat since. At 37 employees, the company has used that base to widen its product line rather than raise again, adding CRM data-quality agents and an ads-buying agent onto its campaign-content platform, alongside a growing sales hiring push and sponsorship appearances like Forrester's B2B Summit.
Agent Readiness
Measures how easily your agents can build on it — API, MCP, CLI, SDK, docs depth. Methodology →
Tofu has no public API, MCP, or SDK documentation on file yet. What is public is the product's own build-out of agent features: named CRM agents (Audit, Dedupe, a decay-aware Fields monitor, a chat-based Data-Quality Agent) launched in June 2026, followed by an Ads Agent in July that assembles CRM-matched audiences and builds full ad campaigns from a brief, live on LinkedIn and Google Ads with Meta support stated as coming soon.
