• Repello AI raised $1.2 million led by Venture Highway (now General Catalyst), with backing from Pi Ventures, Entrepreneur First, and angels like Charles Songhurst and Sarvam AI’s CEO.
• Its core tools ARTEMIS (automated red teaming) and Repello Guard (runtime protection) secure generative AI models against adversarial attacks, prompt injections, and unsafe outputs.
• Already deployed by Groww and PhysicsWallah, Repello will use the funds to expand globally, integrate into CI/CD pipelines, and scale product and brand development.

Repello AI, a security startup with a focus on GenAI, has secured $1.225 million in seed capital to support its endeavor to protect generative AI systems from future threats. Started in 2024, the firm is developing continuous AI red teaming and guardrail solutions in its marquee platforms, ARTEMIS and Repello Guard.

The round is also joined by Venture Highway (which is now a part of General Catalyst), pi Ventures, Entrepreneur First, and respected angel investors Charles Songhurst, a board member at Meta, Vivek Raghavan, CEO of Sarvam AI, and Satya Vyas, CEO of Project Hero.

The company's flagship product, ARTEMIS (Automated Red Teaming Engine for Mapping, Identification and Scanning), actively scans GenAI models for risk across modalities of text, image, and audio. To this is added Repello Guard, a runtime security solution that filters out dangerous outputs and alerts on risks such as prompt injection, competitor references, and prompt leaks in real-time.

It's an inflection point where AI adoption is speeding up greater than security solutions can, and enterprises are deploying generative AI in every function, but they're playing yesterday's security playbook", commented Aryaman Behera, Repello co-founder and CEO.

During an exclusive conversation with AIM, Behera pointed to spikes in real-world malfunctions, such as a car dealership chatbot approving $1 transactions, as proof that AI safety cannot come later. He went on to clarify that it is similar to owning a house without a door for generative AI uses without safety. "You need such guardrails in order to safeguard your AI infrastructure", he further 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 boasts live deployments with companies such as Groww and PhysicsWallah, and is in the process of operating proof of concepts (POCs) throughout the US, Europe, and Middle East. 

Although not disclosed are specific revenue details, the new capital will serve to scale products, increase brand authority, grow go-to-market strategies, and establish global partnerships.
