About
From being found on the web to being recommended by AIs
Epovest is one craft, practiced since 2002: making businesses visible, and keeping a hand on what is said about them. Here is the story, and the rules we hold ourselves to.
The story
From a first homepage to a method anyone can run.
-
2002
A first site, a first lesson
Simon Vasconcelos Lee puts his first websites online while studying mathematics in Paris. The thrill of publishing fades fast: a site simply posted on the web does not get visited. Being found takes work, and that work becomes his craft: improving his clients' visibility on the Internet, and watching over what is said about them online. Online reputation management, before the phrase was everywhere.

2015
The models enter the toolbox
Google releases TensorFlow, its open-source machine learning library. Simon starts studying and experimenting with AI models the year they become available to everyone. The fundamental work comes first; the applications follow.
-
2021
Epovest, for large accounts and VIPs
The craft takes a name and a home: Epovest, an online reputation service then reserved for large accounts and VIP clients, with methods built on artificial intelligence, TensorFlow included, on the epovest.com domain registered that year.

2022
ChatGPT moves the finish line
At the end of 2022, ChatGPT reaches the general public: a technological revolution on the scale of the printing press or electricity. The future of search now sits with the AI labs, and the question changes. It is no longer which links come up: it is what the answers say, and whom they recommend.
-
2026
The method, opened to everyone
After nearly a quarter of a century and thousands of clients served, from large accounts to VIPs, Simon and his team decide the know-how should no longer be reserved for a few: the Epovest app is born. The company is structured to serve clients worldwide: Sels de Rehy, LLC, incorporated in Delaware, United States.

Today
Proof over promises
The product is proven the only way that counts: on ourselves. To make Epovest known we use exclusively our own method and the tools we sell, and we buy no advertising. So if you have reached this page, the method did its job.
Why "Epovest"?
From the Czech pověst: one word that means both legend and reputation. Add an e for the online world: e-pověst, Epovest. The craft it names, online reputation, was there from the very start.
The company
Epovest is a brand operated by Sels de Rehy, LLC, a limited liability company incorporated in the State of Delaware, United States, serving clients worldwide. Data is processed in the United States and, depending on the processors, in the European Union, with the safeguards the GDPR requires.
The rules we hold ourselves to
Standing commitments, the same for every client, and verifiable in the product.
- No subscription: prepaid credits, and only the checks that run are debited
- Your prompts are asked verbatim, through the engines' official APIs
- Every answer is archived with its cited sources, dated and verifiable
- Everything the app shows can be read and driven by your AI assistant, through the API and MCP
- Everything leads to action: where to appear, what to fix, proof of what changed
- Our own marketing runs on Epovest alone: our method, our tools, and no paid advertising
With Epovest, businesses make AIs recommend them.
The founder
Simon Vasconcelos Lee
Founder
A French-Portuguese entrepreneur trained in pure mathematics: classes préparatoires MP* in Paris, then a magistère in mathematics at Université Paris XI in Orsay. The mathematical habit runs through the product: measure, date, verify.
He has studied and experimented with AI models since TensorFlow was released in 2015, and his companies have served clients in 42 countries. Epovest is where the two meet: artificial intelligence, put to work on a craft practiced since 2002.
