Making Equal Access to Justice a Reality
Aegis Legal AI turns existing and new law firms into AI-native law firms, delivering attorney-supervised legal services at a fraction of traditional cost.
"The U.S. legal market has no shortage of lawyers, but it has a delivery problem. IP legal support remains too expensive, too opaque, and too slow for the startups, e-commerce sellers, and SMEs whose businesses depend on it. Aegis is building the AI-native legal service model that can make high-quality IP protection scalable for the first time."

"'Equal Justice Under Law' is carved into the U.S. Supreme Court building. It is also one of the reasons I went to law school. But after years serving e-commerce sellers, I saw a painful gap between that principle and reality. Every day, sellers came to me with IP disputes, platform complaints, frozen accounts, TROs, and other urgent legal problems. Many had strong arguments and real business losses, but they could not afford U.S. attorneys' hourly fees. This is why I founded the Aegis Legal AI, making equal access to justice a reality!"

Mission & Vision
Why We Exist
Turn existing and new law firms into AI-native law firms, delivering attorney-supervised legal services at a fraction of traditional cost & making equal access to justice a reality for e-commerce sellers and SMEs.
What we aspire to
A world where high-quality U.S. legal support is within reach of everyone. AI-powered, attorney-supervised, and transparently priced.
The Founding Story.
The Problem We Kept Seeing...
Many of our friends are e-commerce sellers and SME owners. We have seen them face the same problem again and again: serious IP risks, but no affordable way to get U.S. legal help. Every year, millions of products are sold online without proper IP risk review. Thousands of brands are copied by infringers. Hundreds of thousands of sellers face platform complaints, product takedowns, frozen accounts, or TRO orders in U.S. IP lawsuits.
Equal Justice Under Law...
"Equal Justice Under Law" is carved into the U.S. Supreme Court building — a principle that motivates many attorneys. But after years serving e-commerce sellers, a painful gap remains between that ideal and reality. Every day, sellers face IP disputes, platform complaints, frozen accounts, TROs, and other urgent legal problems. Many have strong arguments and real business losses, yet cannot afford U.S. attorneys' hourly fees.
This Felt Fundamentally Unfair...
When these problems happen, sellers urgently need lawyers, but traditional U.S. legal fees are often too expensive. Many are forced to absorb huge losses, abandon products, or lose their stores entirely. As a former strategy and data consultant, I believed AI could make legal services faster, more affordable, and more accessible, without removing attorney supervision where it matters. That is why I founded Aegis Legal AI in 2024.
Aegis Was Founded to Change That...
For large corporations, equality before the law is real because they can afford legal representation. For millions of e-commerce sellers, SMEs, and consumers, equal access to justice often remains only a dream. Aegis Legal AI was founded to help change that. Our first vertical focuses on one of the most urgent needs for sellers and SMEs: affordable IP legal services.
What We Built...
We combine IP legal workflows, updated IP and court data, advanced AI models, and attorney supervision to build practical legal AI agents. Today, Aegis has developed more than 10 IP law AI agents, helping thousands of sellers access legal support that would otherwise be too expensive or too slow. These agents cover IP compliance, infringement detection, TRO response, platform complaints, brand protection, and related disputes.
A Better Model for Everyone...
Clients gain full visibility into their cases, with no surprise bills and clear fixed-fee pricing at a fraction of traditional law-firm costs. Attorneys, in turn, are freed from repetitive client communication, data processing, document organization, and billing records, allowing them to focus on legal strategy, professional judgment, and high-quality outcomes. Aegis creates a more transparent, efficient, and result-driven legal-service model for both clients and attorneys.
This Is Only the Beginning...
We are excited to work with more attorneys and boutique law firms to build AI-native legal services and make affordable legal support available to every business and individual who needs it. Aegis Legal AI. Making Equal Access to Justice a Reality.
