Tofu

Overview

Tofu is a marketing automation platform designed to streamline and accelerate various marketing workflows, including 1:1 Account-Based Marketing (ABM), outbound prospecting, content marketing, events and webinars, customer marketing, and lifecycle marketing. Founded in March 2023 by Eunjoon (EJ) Cho, Elaine Zelby (former marketing leader at Slack, Consensys, and Capriza), and Honglei Liu (ML leadership background), Tofu is based in San Mateo, California. The platform leverages generative AI to create unlimited variations of on-brand content for ads, emails, social media, landing pages, blog posts, case studies, and sales enablement materials. By integrating brand guidelines and segmentation (personas, industries, accounts, keywords), Tofu automatically generates personalized content at scale, reducing content creation time from days to minutes. This enables marketing teams to run 1:1 ABM campaigns to hundreds of target accounts across all channels simultaneously. Key capabilities include automated account and contact research, scalable prospecting campaigns across email, phone, LinkedIn, and personalized landing pages, AI-generated content that maintains brand consistency, and integrated campaign orchestration that coordinates messaging across multiple touchpoints. The platform can scale 1:1 ABM campaigns to 100s of target accounts across all channels, with campaign setup reduced from weeks to under 10 minutes. Tofu serves enterprise B2B companies with high-value accounts requiring personalized engagement. Notable customers include Snowflake, Databricks, and Wunderkind. Case study results show Wunderkind personalized content for over 1,000 accounts, resulting in a 133% boost in email engagement, while Tofu's automation reduced campaign launch time from days to minutes. The company raised $5 million in seed funding in October 2023 led by Index Ventures, with participation from SignalFire, Stage 2 Capital, and Liquid 2 Ventures, followed by a $12 million Series A led by SignalFire in May 2025, bringing total funding to $17M. Despite having only 27 staff, Tofu already supports global enterprises with contracts that rival typical Series A metrics. What differentiates Tofu is its focus on rebundling and automating the fragmented B2B marketing stack. Rather than requiring multiple tools for content creation, ABM orchestration, and campaign execution, Tofu provides an integrated platform where AI handles the heavy lifting of content generation and personalization, while marketers focus on strategy and optimization. The platform's ability to maintain brand voice while generating thousands of variations solves a key challenge in scaling personalized marketing.
