Tofu is an AI-native marketing platform designed to help B2B teams execute personalized, multichannel campaigns without the manual grind of producing dozens of asset variants by hand. The platform ingests a company's brand guidelines, product positioning, messaging frameworks, and existing content, then uses that context to generate on-brand marketing assets, including landing pages, emails, blog posts, whitepapers, case studies, ad copy, and social content. Crucially, Tofu personalizes that content at scale across dimensions like industry, persona, account, and funnel stage, which is where most account-based marketing programs stall.
The product is positioned as a consolidation play against martech bloat. Modern GTM teams often juggle separate tools for content generation, personalization, landing pages, and campaign orchestration, with brand consistency degrading at every handoff. Tofu unifies campaign execution in a single platform, letting marketers spin up a full multichannel campaign, personalize it for many segments, and repurpose a single piece of content into many formats and channels. This dramatically compresses the time from campaign concept to live execution.
Tofu was founded by Elaine Zelby, Honglei Liu, and Eunjoon (EJ) Cho, whose backgrounds span product, engineering, and marketing leadership roles at companies including Google, Meta, Slack, Affirm, and Twitter. The founding insight came from experiencing the pain of B2B campaign personalization firsthand. The company targets mid-market and enterprise B2B marketing teams that run sophisticated, segment-heavy go-to-market motions.
Tofu raised a $5 million seed round in October 2023 led by Index Ventures, followed by a $12 million Series A in February 2025 led by SignalFire with participation from HubSpot Ventures, Tau Ventures, and others, alongside existing investors Index Ventures, Stage 2 Capital, and Liquid 2 Ventures. The company reported a 12x revenue increase and a 36x surge in content generated on its platform, and is using the funding to consolidate martech for enterprise GTM teams.
