Founded by Leonardo Lupiano and Rhet Porter, Notorio is targeting a gap in the legal tech market with a platform that helps founders organise and manage their company’s legal infrastructure. From compliance and corporate records to cap table management and AI-assisted guidance, the startup aims to become a one-stop hub for businesses, particularly international founders establishing a presence in the United States.
How would you describe your company to a friend?
Running a company creates a surprising amount of legal housekeeping. Corporate documents, ownership records, compliance deadlines, agreements and other important information often end up spread across inboxes, folders and spreadsheets.

Notorio gives founders one place to keep the legal side of their business organized and know what needs their attention.
And to a techy?
Notorio is a founder-first legal technology platform for managing a company’s legal infrastructure.

It combines structured company data, document management, compliance workflows, cap table and ownership information, automation, and AI-powered review and guidance in one environment.
The idea is that these functions work better when they share the same company data. Instead of treating a document, ownership change or compliance obligation as an isolated event, Notorio can connect that information across the company and help the founder understand what is there, what may be missing and what needs to happen next.
When were you founded?
June 2025.
By who?
Notorio was founded by Leonardo Lupiano in June 2025. Rhet S. Porter became involved shortly afterward and joined as co-founder.
The two had met while working at a startup incubator, where they were exposed to early-stage companies and the challenges founders face as they grow.
Who are your key managers/senior execs?
Leonardo Lupiano and Rhet S. Porter, co-founders.
Leonardo founded Notorio after working in the startup ecosystem and seeing how fragmented the legal and corporate side of running a company could become. He has a background in startups, business and technology and is currently attending law school, where his interest in legal technology and corporate law has continued to shape the platform.
Rhet became involved shortly after Notorio was founded. He has a background in finance and has built and operated companies across multiple industries, including construction and education.
They are supported by a board that includes attorneys, founders and business leaders with experience across law, technology and entrepreneurship.
Who are your target clients?
Founders and business owners.
A lot of legal technology is built for the lawyer. Notorio approaches the relationship from the other side, focusing on the person actually running the company and trying to keep its legal infrastructure in order.
The platform has a particular focus on international founders who want to enter the U.S. market or establish a credible U.S. presence as they take their companies global.
Creating the entity is the easy part. After that comes ownership, corporate records, compliance, agreements, filings and the ongoing work of maintaining a real U.S. business. For a founder doing that from another country, the process can become fragmented very quickly.
What is your plan (growth strategy)?
Start with the legal infrastructure every company needs, then become more valuable as the company grows.
A founder may initially come to Notorio to organize corporate records or manage compliance. As the business develops, the same platform can support ownership and cap table management, governance, documents, compliance workflows and other recurring legal and administrative needs.
A major part of that growth strategy is deeper AI integration throughout the platform. Rather than treating AI as a standalone chatbot that generates or reviews agreements, Notorio is being designed to work with a company’s actual records and workflows. That includes helping founders review documents, identify missing information, understand compliance obligations, manage corporate records and work with cap table and ownership data more intelligently.
International expansion is also an important part of the strategy. Notorio aims to become a natural starting point for foreign founders building a serious presence in the United States.
Partnerships are another important distribution channel, particularly with startup incubators, accelerators, universities, professional organizations and other institutions that already support founders. The goal is to put Notorio in front of businesses at the stage when they are beginning to formalize their legal and corporate infrastructure.
Key achievements?
Building traction in legal tech without outside capital.
Notorio has grown from an idea founded by Leonardo Lupiano into a working legal technology platform with paying customers, with Rhet Porter joining shortly after its founding as co-founder. Together, they have built and iterated on the core platform themselves, allowing Notorio to stay lean and develop the product without raising outside capital to fund engineering.
Notorio has also started gaining recognition within the legal technology industry. In September 2026, Law360 published a Legal Tech Talks feature by Leonardo discussing Notorio’s origins and the challenges of building and evaluating legal technology.
Have you received investment?
No outside investment.
Notorio has been funded by its co-founders and supported by customer revenue. Building the platform in-house has allowed the company to stay lean and continue developing the product without relying on external capital.
Have there been any key changes in direction since you were founded?
Yes, but the underlying problem has stayed the same.
The original idea was much closer to incorporation services. While exploring that market, the founders realized that incorporation is a relatively small moment in the life of a company. The harder problem is everything that comes after it.
Companies have to maintain corporate records, track ownership, manage documents, meet compliance obligations and keep their legal information organized for years. That shifted Notorio from helping create a company to helping manage the legal infrastructure behind one.
That realization became the foundation for the platform Notorio is building today.
What are the key challenges in your market?
Trust and clarity.
Legal technology has historically been built primarily around lawyers and law firms. Notorio approaches the problem from the business owner’s perspective, which means making sophisticated corporate and legal processes understandable and useful to founders who may not have legal training.
The challenge is giving founders better tools to stay organized, understand what requires attention and manage more of their company’s legal infrastructure without creating the impression that technology replaces professional legal advice.
As AI becomes more capable, that balance becomes even more important. The opportunity is to use technology to make founders better informed and better prepared while preserving the role of attorneys where legal judgment is needed.
Tell us something people don’t already know about the company?
Leonardo is originally from São Paulo, Brazil, and moved to the United States before founding Notorio. Rhet grew up in rural Utah, giving the company two very different founder perspectives.
Leonardo’s experience building a career and starting a company in a new country gave him firsthand exposure to some of the practical challenges founders face when trying to establish themselves in the U.S. That perspective helped shape Notorio’s focus on international founders and its goal of making it easier for entrepreneurs from abroad to build and manage a credible U.S. business presence.
