JustAI Raises $17M in Series A Funding Led by Base10 Partners

The round also saw participation from Y Combinator and Peak XV Partners, and investors and operators from Anthropic, Chime, and Notion, the CTO of HubSpot, and the founders of Eppo and Vapi.

The company plans to use the funding to expand its engineering and sales teams, strengthen its AI agent infrastructure, and enhance the platform with new capabilities.

Marketing and growth teams are being asked to produce more content, deliver greater personalization, and drive better results without adding staff or using more software tools. At the same time, the marketing technology market has become increasingly crowded and complex.

The 2025 Marketing Technology Landscape identified more than 15,000 martech products. While Gartner's 2026 CMO Spend Survey found that marketing leaders are investing 15.3% of their budgets in AI, only 30% feel prepared to scale AI across their organizations.

JustAI increased its annual recurring revenue by five times this year and aims to transform how marketing is managed in large enterprises. The platform combines AI agents for strategy, content creation, decision-making, and data analysis to help marketing teams automate more of their work.

Instead of relying on manual processes, fixed rules, and disconnected tools, JustAI provides a single system that understands customer context, creates campaigns, optimizes decisions, and continuously improves based on performance results.

"JustAI is one of the few teams building a true decisioning and measurement layer for marketing teams that marketers have needed, and the traction backs it up: 5X ARR growth and over $100 million in customer revenue influenced last year. Neha and Jeff combine hard-won growth experience with deep ML depth, and we're honored they chose us as partners for this round," noted Rexhi Dollaku, General Partner at Base10 Partners.

When describing how JustAI unlocked new capabilities at Coursera, Director of Marketing Vera Hui said: "It would have required a dev team in the past, wouldn't have done it myself." JustAI enables companies to predict the next best message or action for each user, replacing manual workflows and deterministic campaign logic with adaptive, AI-powered decisioning. Its infrastructure is designed to execute hundreds of sophisticated campaigns built by agents at scale while giving marketers visibility and control over the system.

"We want marketers to spend less time managing tools and more time making the decisions that drive growth," said Neha Mittal, Founder and CEO of JustAI. "Marketing teams have spent the last decade buying more tools to manage more workflows. But the real opportunity with AI is not another dashboard or another automation layer. It is giving every great marketer the ability to operate with the leverage of an entire team. JustAI is the infrastructure for that shift."
