Rafael
Umann

In the mid-1990s, somewhere in southern Brazil, a 13-year-old named Rafael Umann was not playing video games. He was running an internet service provider. Not a school project. Not a lemonade stand. A real ISP, with real customers, that got noticed by a real internet group, and was acquired - four years after he started it.

That exit, his first of several, is the cleanest summary of who Rafael Umann is. He doesn't learn technology and then apply it. He builds with it. From a teenager wiring up dial-up subscribers in Brazil to a CEO running a global edge cloud from Palo Alto, the throughline is the same: infrastructure is where leverage lives, and he wants to be the person who controls it.

After his ISP was acquired, Umann joined Terra Networks, one of Latin America's largest internet companies at the time. He became a systems and infrastructure engineer, and somewhere in the early 2000s, started contributing to the Linux kernel. One of those contributions - device drivers and network code he wrote - ended up powering what was then the world's largest point-to-point wireless network. That is not a line from a press release. It is listed quietly in his biography, the kind of fact that only impresses people who understand what it means.

Before Airbnb, There Was VP2U

By 2004, Umann had relocated to London to co-found VP2U, an online marketplace for renting properties and spare rooms. The model was what we now call Airbnb - except Airbnb wouldn't launch until 2008. VP2U operated across five countries: Brazil, Ecuador, Colombia, Portugal, and Poland. It built thousands of customers and hundreds of properties under management. Then it sold. His second exit, years before the terminology "sharing economy" entered the mainstream.

He returned to Brazil. Studied business. Then earned two executive MBAs at Columbia Business School - one in Sales and Marketing Strategies, one in Business Administration and Management. He had already dropped out of his Computer Science degree to run his first company. Columbia felt less like a credential and more like a deliberate step: he wanted to understand the full stack, not just the technical layers.

Building Azion: From Brazilian CDN to Global Edge Cloud

In 2011, Umann founded Azion Technologies in Brazil, initially as an IT infrastructure and content delivery network provider. For years it was a solid, respected regional player. Then something shifted. The market started moving toward the edge - not just CDN, not just cloud, but a new distributed computing model where logic, security, and processing happen at the network boundary rather than in a central data center.

Umann repositioned Azion around that shift. By 2020, the company raised a Series A led by Monashees and Qualcomm Ventures. Qualcomm Ventures investing in an edge computing platform was not accidental - Qualcomm makes the chips that power edge devices. The vote of confidence meant something. Azion moved its headquarters to Palo Alto, California and began competing internationally.

In July 2022, Azion launched its Edge Marketplace - a global application store for edge-native software, including authentication, fraud protection, AI, analytics, and developer tools. Umann described it as the App Store moment for edge computing: a place where developers could build once and deploy everywhere across Azion's global network.

What Azion Actually Does

Azion runs a distributed computing platform with 100+ points of presence around the world. Customers use it to serve web applications faster, protect against DDoS attacks and bots, run serverless functions at the network edge, stream data in real time, and manage security policies programmatically. The pitch to enterprises is straightforward: instead of waiting for traffic to travel to a centralized cloud, process it closer to where the user is. Less latency. More security surface area. Better economics at scale.

The numbers are not hypothetical. 45 of the 50 largest e-commerces in Latin America rely on Azion. 20 million students access educational content through infrastructure Azion runs. 10 billion financial services transactions move through Azion's platform every month. This is not a startup with a demo. It's infrastructure.

The Awards Year

2023 was Azion's coming-out year on the global stage. In August, GigaOm named Azion a Market Leader and Fast Mover in its Edge Platforms radar - the only edge-specific platform to meet all of GigaOm's essential criteria. In July, Frost & Sullivan awarded Azion the North American New Product Innovation Award for Edge Serverless Computing. In Q4, Forrester named Azion a Strong Performer in its Edge Development Platforms Wave, with maximum scores in Observability.

And then, at Web Summit in Lisbon, Azion won the Santander X Global Challenge in the Cyberprotect the Future category - Scaleup track - competing against 250+ startups and scaleups from 11 countries. The other winners were Calypso AI (USA) and Surf Security (UK). Umann accepted the award in person.

Umann commented afterward: "This recognition will serve as a springboard for further research and development to enhance Azion's solution." The sentence is polished, but the fact behind it is the real story: a company he built from scratch in Brazil had just beaten hundreds of global competitors on a global stage.

The Edge Argument

Umann has been making the same argument in different forms for years. The cloud was a revolution, but it created new dependencies. Latency, centralized outage risk, ballooning costs, security perimeters that are too porous at the edge - these are structural problems, not bugs to be patched. The answer is distributed infrastructure that moves intelligence closer to where data is generated and consumed.

He is not alone in making this argument, but Azion is one of the few companies that has built production-grade infrastructure around it rather than just thought leadership. The Azion Academy, a developer learning platform, and the Code-to-Edge coding contest he has promoted, reflect a calculated investment: the more developers understand the edge, the larger the market for Azion becomes. He is building the ecosystem, not just the product.

Umann is a Forbes Technology Council member, an LP in VC funds and startup incubators, and a board member at WOW Aceleradora. He writes, speaks at conferences, and takes press calls. But his day job is running a company with 310 employees, operations across the Americas and Asia, and a platform processing billions of events daily. He is mid-sprint, not mid-reflection.
