JustAI Raises $17 Million to Grow Its Agentic Martech Stack

JustAI is an AI marketing startup. A startup is a new, young company. JustAI has just raised $17 million. “Raised” means it got money from investors. Investors are people or firms who give money to a company hoping it will grow and pay them back later.

This money came in a Series A round. A round is one time a startup collects money. A Series A is the first big round, after the startup has shown its idea really works. The $17 million is about Rs 160.2 crore in Indian money.

JustAI will use the money to grow its “agentic martech stack.” Let us break that down. “Martech” is short for marketing technology, which is software that helps sell things. “Agentic” means the software uses AI agents. An AI agent is a smart computer helper that can think, plan, and act on its own. A “stack” is just the set of tools working together. So JustAI uses smart AI helpers to run marketing for big companies.

The round was led by Base10, a US firm. “Led” means Base10 put in the most money and guided the deal. Many big names joined too. This shows they strongly believe in AI-driven marketing.

What does JustAI do?

JustAI used to be called Just Words. It changed its name in late 2025. The company makes software for big businesses. The software writes and sends marketing messages to customers.

In simple words, it sends the right message to the right customer, to lots of people at once, using AI. This saves a lot of time.

The software runs on four AI agents that work together. Each agent has one job:

• The strategy agent studies the customers and sorts them into groups.
• The creative agent turns those facts into real messages.
• The decisioning agent picks the best plan to reach a goal.
• The data agent checks the results and sends feedback.

Together, these four agents do the whole marketing job with very little human help.

JustAI was started by Neha Mittal and Jeff Hara. Both used to be top bosses at X. X is the company that used to be called Twitter. JustAI’s customers include big names like Coursera, ClickUp, Better, Figma, Pinterest, and Etsy.

Who invested in JustAI?

Base10 led the round. Base10 is a US venture capital firm. A venture capital firm is a company that gives money to young startups, hoping they grow big.

Two more groups joined: Y Combinator and Peak XV Partners. Y Combinator is a famous startup accelerator. An accelerator is a program that helps new companies grow fast and gives them money early on.

Some well-known people also put in their own money. These people are called angel investors. They include Dharmesh Shah, the co-founder and CTO (chief technology officer, the top tech boss) of HubSpot. The founders of two companies, Eppo and Vapi, joined too. So did bosses from Anthropic and Chime. Having both marketing and AI experts on board is a strong sign of trust.

Where will the money go?

JustAI will use the money to hire more people. It will add to its engineering and sales teams. It will also make its AI infrastructure stronger. Infrastructure is the technical base that keeps the AI agents running.

The company also wants to grow into new areas. One is ecommerce, which means buying and selling online. The other is B2B marketing. B2B means business-to-business, where one company sells to another company.

This part is big for India. JustAI plans to hire people here and look into the Indian market. That shows it sees India as a place to grow. Before this round, the startup had raised $1.7 million in 2024. That earlier round was called a seed round, which is the very first small round of money for a young startup.

Why it matters, especially for India and founders

India’s martech market is expected to reach $186 billion by 2030. That is a huge amount. JustAI’s plan to hire and grow in India shows something important. Global AI startups now see India as a key place to build.

For Indian founders, agentic AI is clearly the hot topic. A founder is a person who starts a company. Investors are now backing startups that use AI agents to do real work. This deal sits next to other agentic AI bets. One example is Hang Ten, the new AI company from Vishal Sikka, the former chief of Infosys. It also uses AI agents for company tasks.
