Tofu

It is a Tuesday morning at a B2B marketing team somewhere, and a campaign that once took three weeks is going out before lunch. Not because someone worked through the weekend, but because Tofu wrote the first ninety percent of it overnight - then waited for a human to say yes. That is the company in one sentence: software that does the marketing busywork and leaves the judgment to you.

Tofu is an AI-powered, omnichannel marketing platform for go-to-market teams. It plugs into the tools companies already run - HubSpot, Salesforce - and turns a single brief into hundreds of on-brand, on-channel messages. Today it has about 35 employees, $17 million in the bank, and a customer roster that includes RingCentral, Check Point and Wunderkind. Not bad for a company that, as of late 2023, did not exist.

A stack that ate the marketer

Somewhere along the way, marketing software multiplied. A team that wanted to run one campaign ended up paying for a content tool, a personalization tool, an email tool, an analytics tool, and a tool to make the other tools talk to each other. Each one promised leverage. Together they produced tabs - dozens of them - and a marketer whose actual job had quietly become tool administration.

Tofu's founders had lived this. CEO EJ Cho first felt the pain in 2018, juggling marketing tools while launching his first company. Before building anything, the founding team interviewed more than 40 CMOs. The complaint was remarkably consistent: the stack was too big, the personalization was too shallow, and nobody had time to do both well.

Engineers who learned to love marketers

Tofu was founded in 2023 by three people who had seen scale up close. Eunjoon "EJ" Cho (CEO) and Honglei Liu brought years of product and engineering work from Google, Meta, Affirm, Twitter and Fast. Elaine Zelby brought the other half of the equation: nearly a decade building and leading marketing teams at Slack, Consensys and Capriza. One side knew how to ship AI. The other knew exactly what marketers hated about their Mondays.

Their bet was counterintuitive for the generative-AI gold rush of 2023. Instead of selling yet another point solution, they would build a platform that quietly did the job of many - and, crucially, one that lived inside the customer's existing stack rather than demanding a rip-and-replace. Index Ventures backed the idea with $5 million in seed funding that October.

Three founders, two disciplines, one shared grudge against the 14-tab campaign workflow.

One brief, every channel

Here is what Tofu actually does. You give it a campaign goal, your brand voice, and the segments you care about. It generates content and then repurposes it - automatically adapting the copy for email, ads, landing pages, outbound sequences and more. It handles demand generation, content marketing, lifecycle marketing, event follow-up and SDR outreach. The phrase the company uses now is "agentic GTM": campaigns that run on their own inside your stack, always on.

The deliberately unglamorous part is the integration. Tofu reads from and writes to HubSpot and Salesforce, so the personalization is grounded in real account data rather than generic prompts. As Cho puts it, the platform can "replace and support the multiple use cases you're purchasing individual tools for." The marketer stays in the loop - approving, editing, steering - but stops doing the copy-paste.

From idea to $17M

Numbers, logos, money

Skepticism is fair - generative AI for marketers is a crowded, hype-prone room. So here is the evidence Tofu offers. In its first full year, revenue grew 12x and the volume of content generated on the platform rose 36x. Customers report cutting campaign creation time by up to 75% and lifting engagement rates by 230%. The logos backing those claims - RingCentral, Check Point, Wunderkind, Bluecore, DeepScribe - are the kind of buyers who do not sign up for novelty.

Then there is the money, which is its own kind of proof. Across a seed and a Series A, Tofu has raised $17 million. The Series A in February 2025 was notable for who showed up: HubSpot Ventures, the investment arm of one of the very platforms Tofu integrates with. When the incumbent invests in the thing built on top of it, the thesis has a witness.

Consolidation, not addition

Tofu's stated mission is plain: build a unified AI platform for B2B go-to-market teams that consolidates martech and runs personalized, omnichannel campaigns at scale. Read it twice and the ambition shows - the goal is not to win a category, it is to collapse one. Where the last decade of martech sold marketers more, Tofu's vision is a team freed from tool-juggling, with agentic AI handling the always-on grind and humans handling the judgment.

It is a contrarian position dressed in modest language. The competitors - Jasper, valued north of $1.5 billion; Cordial, with $70M-plus raised - are formidable. Tofu's answer is not to out-feature them but to out-simplify them.

Back to that Tuesday

Return to the marketing team and its Tuesday morning. The campaign that used to take three weeks went out before lunch - personalized across channels, grounded in real CRM data, signed off by a human who actually had time to think about strategy instead of formatting. Multiply that across a year and you get the 12x and the 36x. Multiply it across an industry and you get a different shape of marketing job altogether.

That is the wager Tofu is making for tomorrow: that the winning marketing tool of the AI era will not be the one with the most features, but the one that quietly removes the most work. The stack got fat. A small team in San Mateo is betting it can put it on a diet - and so far, the numbers are eating.
