Repello AI Secures $1.2M to Automate Red Teaming and AI Guardrails

Repello AI, a GenAI-focused security startup, has raised $1.225 million in seed funding to bolster its mission of securing generative AI systems against emerging threats. 

Founded in 2024, the company is building continuous AI red teaming and guardrail solutions under its flagship platforms, ARTEMIS and Repello Guard.

The funding round includes participation from Venture Highway (now part of General Catalyst), pi Ventures, Entrepreneur First, and notable angel investors including Charles Songhurst, a Meta board member, Vivek Raghavan, CEO of Sarvam AI, and Satya Vyas, CEO of Project Hero.

The company’s core offering, ARTEMIS (Automated Red Teaming Engine for Mapping, Identification and Scanning), proactively scans GenAI models for vulnerabilities across modalities, including text, image, and audio. Complementing this is Repello Guard, a runtime security tool that filters unsafe outputs and flags risks like prompt injection, competitor mentions, and prompt leaks in real time.

"We're at an inflection point where AI adoption is accelerating faster than security solutions can keep pace," said Aryaman Behera, co-founder and CEO of Repello. "Enterprises are deploying generative AI across every function, but they're doing it with yesterday's security playbook."

In an exclusive interaction with AIM, Behera noted the rise of real-world failures, like a car dealership chatbot authorising $1 purchases, as evidence that AI safety cannot be an afterthought. He explained that it’s like having a house without a door for generative AI applications without security.

 “You need such guardrails in order to protect your AI infrastructure,” he added.

Naman Mishra, co-founder and CTO, told AIM, “With ARTEMIS, we’ve turned red teaming, which used to be a quarterly enterprise task, into an integral part of the AI deployment pipeline when it comes to AI development.” He highlighted that the goal of ARTEMIS and Repello Guard is to ensure fast and secure shipment of the products. 

Repello AI claims active deployments with firms like Groww and PhysicsWallah, and is currently running proof of concepts (POCs) across the US, Europe, and the Middle East.

While specific revenue figures remain undisclosed, the new funding will be used to expand products, enhance brand credibility, scale go-to-market efforts, and form global partnerships.
