JustAI today launched its full-stack agentic marketing platform, which brings CRM, orchestration, creative, delivery infrastructure and measurement into a single AI-native system. The platform is built around two simple ideas: marketing should make money, and every customer should be treated like an individual.
Founded by former Twitter and Pinterest growth leaders, JustAI is expanding from personalization at scale to the entire marketing stack, all powered by its Marketing Harness. JustAI works with companies in education, financial services, insurance and consumer technology, including Coursera, Pinterest, Airtable and Lemonade.
For decades, marketing has struggled to prove its impact on revenue and retention. Nearly half of marketing leaders (48%) admit they are still guessing which activities drive purchases, and 90% say marketers who can’t show business impact will struggle to justify their budgets, according to a 2026 Harris Poll survey for Madison Logic. Teams run hundreds of campaigns, often with murky results, on frameworks built to work around the limits of half-baked tooling.
“After working with hundreds of marketers and tools over the last three years, we realized much of marketing’s complexity, like journeys, snippets and rules, was built around technological limitations. We have to rapidly unlearn all of it in the AI world. It’s time for a new category,” said Neha Mittal, co-founder and CEO of JustAI.
JustAI tackles these problems on three fronts: proving revenue, personalizing every customer’s journey and cutting the work it takes to run marketing. Marketers set the goals and guardrails, and JustAI’s agents handle the rest.
Built Around Revenue
JustAI measures whether marketing campaigns caused customers to engage, spend or convert by comparing customers who received a campaign with similar customers who didn’t. Teams report incremental revenue instead of opens and clicks.
At Better Mortgage, JustAI rebuilt two revenue-critical email journeys and tested them against the originals. The share of pre-approved shoppers who went on to start a full loan application rose 30%, from 9.25% to 12.08%. “Right message, right person, right time was always the goal. JustAI is how we finally get there: AI tests the combinations, and we stop guessing,” said Lilian Gordon, senior lifecycle manager at Better.
1:1 Marketing for Every Customer
JustAI’s agents build journeys and adapt to each customer’s behavior, language and market in real time, while testing which version works best for each person.
At Acorns, JustAI made more than 1,000 AI-driven decisions across 65 million messages, optimizing directly for upgrades and retention, and compressed three years of testing into one month. “No human can pre-write a rule for every customer state. JustAI’s agents don’t need them,” said Simon Shulman, VP MarTech at Acorns.
Operational Efficiency at Scale
Lifecycle teams are asked to deliver more results with the same budget: marketing budgets have held under 8% of company revenue, and 56% of CMOs say they lack the budget to deliver their 2026 strategy, according to Gartner’s 2026 CMO Spend Survey. JustAI pairs the AI agents that create each experience with QA models that take the grunt work and verification off the marketer’s plate, and nothing goes live without the marketer’s approval. Coursera launched three journeys in under two weeks with no engineering work and lifted subscriptions among at-risk learners by 27%.
