CEO Spotlight Interview
Personalized Omni-Channel Marketing Campaigns for B2B Go-to-Market Teams
Eunjoon Cho, CEO & Co-Founder, TofuHQ
Co-Founder Background
EJ Cho is Co-Founder & CEO of Tofu, with over a decade of experience building products at companies such as Google, Meta, and other startups. At her first startup, she saw firsthand the inefficiencies of extreme fragmentation across the martech stack and GTM channels. That experience planted the seed for Tofu — a single place where marketers could create, personalize, and launch campaigns without the inefficiencies of a bloated stack. With deep roots in product development and a clear-eyed view of where go-to-market teams were breaking down, EJ set out to build the platform she wished she had.
“We built Tofu to address this problem directly by giving marketers a single place to create, personalize, and launch campaigns without the inefficiencies of a bloated stack.”
The Founding of TofuHQ
Tofu was founded to solve a problem EJ Cho experienced directly: the painful fragmentation of the modern martech stack. Across a decade of building products at Google, Meta, and early-stage startups, she watched go-to-market teams lose time, consistency, and results to disconnected tools. At her first startup, that friction became impossible to ignore. The answer wasn't another point solution — it was a unified platform that brought campaign creation, personalization, and activation together in one place. Tofu was built to give marketers back the speed and clarity that a bloated stack had taken away.
“We saw firsthand the inefficiencies of extreme fragmentation across the martech stack — and built Tofu to address this problem directly.”
The Problems Being Solved with AI-First Campaign Automation
Tofu helps mid-market and enterprise marketing teams cut through martech bloat by unifying campaign creation, personalization, and activation into a single platform. Intent signals from tools like 6sense and Demandbase show who's ready — Tofu is what comes next. Marketers use Tofu to run personalized ABM and lifecycle programs across email, landing pages, and ads in one place, while staying connected to Salesforce, HubSpot, Webflow, and other GTM tools.
“This unified workflow helps teams move faster, stay on-brand, and drive stronger pipeline results.”
As an AI-first campaign platform, Tofu turns intent signals into integrated omni-channel campaigns — bridging the gap between who's ready to buy and the personalized experience that converts them. By consolidating what once required a fragmented stack of specialized tools, Tofu lets marketing teams focus on strategy and outcomes rather than stitching systems together.
A Future-Forward Partnership: TofuHQ and Tau Ventures
EJ has really valued Tau Ventures' founder-first approach — a combination of conviction and practical guidance that has shown up through in-person events and key introductions. The support over the past year has been meaningful, and she is excited to continue building with the Tau team.
