When EJ Cho founded his first startup in 2018, he encountered the complexities of product marketing and was taken aback by the abundance of single-use tools available in the market.
“It was incredibly frustrating,” Cho shared with TechCrunch. “I had to navigate through a myriad of tools. It struck me as a highly inefficient approach to reach users. Making marketing more efficient and impactful has always intrigued me.”
Cho (seen above on the left) reflected on this concept for several years while he was part of engineering teams at firms like Meta, Affirm, and Fast. Following breakthroughs in generative AI during 2022, he realized he could address the marketing challenges he faced years prior with AI technology.
This insight led to the creation of Tofu, an AI-powered B2B marketing platform aimed at consolidating all potential marketing campaigns into one cohesive space. The platform seamlessly integrates with existing marketing workflows, including tools like HubSpot and Salesforce, and leverages AI to automatically adjust marketing content for various channels while personalizing messages for different customer segments.
As Tofu’s co-founder and CEO, Cho noted that while his initial challenges emerged from developing a consumer-oriented company, his focus shifted to B2B marketing due to its considerably heavier reliance on text, making it a natural fit for a generative AI solution.
To ensure Tofu met market demands, the team engaged with over 40 CMOs before starting development, Cho stated, to identify pressing issues. The two recurring challenges they highlighted were the need to personalize content across various market segments and the desire to repurpose content for multiple channels. Tofu prioritized these areas for initial development.

“When you think about it, the difference between the content for an email and that for a landing page isn’t that vast,” Cho pointed out. “Sure, there are minor distinctions, but they can easily be integrated within a single tool.”
Launched in San Francisco in late 2023, Tofu has experienced robust demand, achieving 12x revenue growth in just over a year. Its clientele includes names like DeepScribe, Check Point, and Wunderkind.
The firm has just announced a $12 million Series A funding round, led by SignalFire, with contributions from HubSpot Ventures, Tau Ventures, Correlation Ventures, and several other existing venture capitalists and angel investors.
While the integration of AI in marketing isn’t a novel idea—nor is it a trend emergent from the ChatGPT boom—there are established players in the field. For instance, Jasper, an AI-driven marketing tool for enterprises, has been operational for a decade and holds a valuation of over $1.5 billion. Similarly, Cordial, another cross-channel marketing solution, has garnered over $70 million in venture funding.
Cho conceded that the market is competitive but believes Tofu’s holistic approach positions it favorably. It caters to various teams across marketing departments, making it more appealing than tools meant for single purposes. He emphasized that Tofu’s comprehensive, integrated solution sets it apart from others that merely act as wrappers for ChatGPT.
With its Series A funding secured, Tofu plans to expand its product capabilities, aiming to establish itself as a foundational resource for marketing teams.
“It’s a crowded market,” stated Cho. “We position ourselves as a comprehensive solution that can replace and support the various individual tools you currently use, offering everything within a single platform. This unified approach presents a highly attractive proposition, particularly for enterprise clients.”
